The invention and use of stainless steel can be traced back to the first World War. British scientist Henry Breerley was commissioned by the ordnance factory of the British government to study the improvement of weapons. At that time, the rifles used by soldiers were very easy to wear, and Brierley wanted to invent a kind of alloy steel that was not easy to wear. A lot of our life is stainless steel, such as kettle, thermos cup, chopsticks, plates, etc. Because of the improvement of safety awareness, more and more people will pay special attention to whether 304 stainless steel is the most important part of stainless steel when choosing stainless steel tableware. Many businesses will indicate that their products are 304. But really, can 304 stainless steel make dinner plates safely?

Is stainless steel plate ideal
Specific test
It can be used, but it is not an ideal tableware, because stainless steel contains a variety of metal elements, some of which are decomposed under the corrosion of vinegar or salt, and damage organs after eating into the human body. Therefore, if you want to achieve absolute food safety, you should still use plates made of ceramic or glass. Ceramic glass is made of oxide sintered at high temperature, and its corrosion resistance is very high, even if there are trace elements Jiena is just soil, which will not damage health after entering the human body. Heavy metal poisoning is accumulated over time, if the long-term intake of excessive heavy metals, it will lead to metal poisoning, life-threatening. Therefore, we all attach great importance to the safety of stainless steel plates.
Everyone's worry is very reasonable - stainless steel tableware is in direct contact with food. If the stainless steel material is not up to standard, the heavy metals in it will be dangerous to migrate into food.
In fact, 304 is an American Standard, which is a brand of stainless steel produced according to American ASTM standards. 304 stainless steel contains 18% chromium and 8% nickel, which has good corrosion resistance. However, our national standard gb4806.9-2016 "metal materials and products in contact with food" does not specify the brand of food grade stainless steel, but stipulates that the stainless steel used in contact with food must meet five heavy metal migration indicators:
In other words, stainless steel tableware is allowed to add some heavy metals in the production process, but the amount of these metals migrating into the food can not exceed the provisions of the above standard. It is very likely to consume excessive heavy metals in the process of long-term use if it exceeds the requirements, which will cause irreparable losses to our lives. Therefore, we must pay attention to the content of various heavy metals in the plate when selecting, so as to avoid excessive intake.
From the standard point of view, to choose food grade 304 stainless steel as the material.
High quality stainless steel is needed to make dinner plate with stainless steel, but this kind of stainless steel generally has less output, complex process and high cost, and few products meet the relevant conditions.

Stainless steel plate since the beginning of the 20th century, has a history of more than 1 century. The stainless steel plate surface is smooth, has higher plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an alloy steel that does not rust easily, but is not absolutely rust free. Stainless steel plate refers to the atmosphere, steam and water and other weak medium corrosion of steel plate, and acid steel plate is acid, alkali, salt and other chemical corrosion medium corrosion of steel plate. However, we should also understand that stainless steel plates will rust and be corroded.

l Rusting
l corrosion
Stainless steel has the ability to resist atmospheric oxidation, that is, the performance of stainless steel, but also has the ability to resist corrosion in the medium containing acid, alkali and salt, that is, corrosion resistance. However, its corrosion resistance depends on the chemical composition of the steel itself, the state of each other, the use conditions and the type of environmental media. But for some reason, this film is constantly destroyed, air or liquid neutralizing oxygen atoms will continue to infiltrate or metal iron atoms continue to precipitate out, forming a relatively loose iron oxide is stainless steel rust. General stainless steel is very easy to rust in the environment of high air humidity, high pH in the air or high pH solution. Of course, the steel smelting process will also affect the corrosion resistance of stainless steel, smelting technology is good, advanced equipment, advanced process, alloy element proportion control is good, the high proportion of impurities removal, billet cooling temperature control is good and not easy to rust, if the surface damage is easy to rust.
The corrosion resistance of stainless-steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal organizational structure, the main role is chromium element. Chromium has very high chemical stability, can form a passivation film on the surface of the steel, so that the metal is isolated from the outside world, protect the steel plate from oxidation, increase the corrosion resistance of steel plate. After the destruction of the passivating film, the corrosion resistance decreases. Following are the corrosion conditions:
l Stainless steel surface deposited with dust containing other metal elements or similar metal particles of the attachment, in the humid air, the attachment and stainless-steel condensate between the two together into a micro battery, triggered an electrochemical reaction, the protective film is damaged, called electrochemical corrosion.
l Stainless steel surface adhesion of organic juice (such as vegetables, noodle soup, sputum, etc.), in the case of water and oxygen, constitute organic acids, long time is the corrosion of organic acids on the metal surface.
l Stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration walls of alkali, limestone splashing), causing local corrosion.
l In the polluted air (such as containing a large amount of sulfide, carbon oxide, nitrogen oxide atmosphere), in case of condensate, the formation of sulfuric acid, nitric acid, acetic acid liquid point, cause chemical corrosion above circumstances can cause the destruction of stainless steel surface protective film caused by corrosion.
Stainless steel plate is generally stainless steel plate and acid-proof steel plate. At the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technical foundation. There are many kinds of stainless steel plates with different performances. Although stainless steel plate has certain safety problems, it is still the first choice of many steels.
Stainless steel sheet surface is smooth, has higher plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. A stainless steel sheet is an alloy steel that does not rust easily, but is not absolutely rust free. Stainless steel is a group of iron-based alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting and also provides heat-resistant properties. Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminum, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum. Specific types of stainless steel are often designated by a three-digit number.

Because of their relatively attractive appearance, stainless steel sheets are used for both decorative and structural purposes. They can be laid over a wood base to create a countertop or table, and are also a popular finish for kitchen backsplashes. Many appliances and machines are made using a stainless steel sheet casing, as are many cars and airplane bodies. Metalworkers use these sheets to create artwork and architectural elements, while electronics manufacturers rely on stainless steel sheets when building equipment casing and some operating components.
1. Before choosing stainless steel sheets, the use and environment of stainless steel sheets should be considered. For example, welded pipes are usually used for decoration, seamless pipes are usually used for fluid transportation, sanitary stainless steel sheets are used for medical treatment or kitchens, and thick-walled pipes are used for pressure. Generally, 200 series materials are sufficient indoors, 304 stainless steel sheets are sufficient outdoors, and 316 materials or above are usually used in acid-base places or coastal areas.
2. When purchasing stainless steel sheets, high-quality products assessed by the Bureau of Quality and Technical Supervision shall be selected. Long-term use of witnesses and good customer reputation are the most direct and effective purchase methods.
Many daily necessities and facilities made of 3004 stainless steel are used in our daily life, such as 304 stainless steel water tanks, stainless steel sinks, etc. These 304 stainless steel products greatly facilitate people’s lives, but people will also encounter them in their lives. To some merchants who use fake 304 stainless steel plates or non-304 stainless steel plates to mislead consumers with fake 304 stainless steel plates or non-304 stainless steel plates, which has brought immeasurable losses to consumers.

Today we are going to introduce a common stainless steel product, it is stainless steel coil , however, many people have doubts about the quality of stainless steel coil , this article will answer your doubts.
Why stainless steel coil is good quality?
What’s the 201 stainless steel coil ?
Why use the stainless steel coil ?
There is no doubt that the quality of stainless steel coil s is very good. The primary reason for this is the stable chemical composition of stainless steel coil s, the purity of the steel and the low content of inclusions. Secondly, the strict surface treatment of stainless steel coil s gives them good resistance to corrosion and heat. As an example, 304stainless steel coil is one of the most widely used stainless and heat resistant steels. It is widely used in food production equipment, general chemical equipment, nuclear energy, etc. In terms of raw materials, our steel metal ensures optimum packaging quality because it plays an important role.
201 stainless steel coil is a common type of stainless steel coil which has some resistance to acids and alkalis and has a high density. Commonly used stainless steel sheets are divided into two steel grades, 201 and 304, which are actually different in composition and the quality of 201 stainless steel coil may not be as outstanding compared to 304 stainless steel. It is worth noting that in some specific applications 201 stainless steel coil has the potential to replace 304 stainless steel.
·A wide range
The large variety of stainless steel coil s means that there is a wide range of applications for stainless steel coil s. Whether in the industrial, chemical, construction or medical sectors, stainless steel coil s are used.
·Good quality
Good corrosion/heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping/bending and no heat treatment hardening. the high quality of mainless stell coils also means that they have a high dimensional accuracy of ±0.1 mm.
stainless steel coil stainless steel coils are not only corrosion resistant, but also relatively light in weight, so there are many applications for stainless steel coil s. However, in the use of stainless steel coil needs to be noted that stainless steel exposed to a corrosive environment in the metal surface electrochemical or chemical reactions occur, uniformly subject to corrosion.
