Unlike iron, which has been in use for more than a thousand years, stainless steel is a relative newcomer to materials science, first produced only 100 years ago. This may seem hard to believe at first, given the near-ubiquity of metals in modern life, but it's just a testament to how important a breakthrough stainless steel is. The metal has revolutionized the modern world, with applications in almost every area of manufacturing, from healthcare and catering equipment to the automotive and construction industries. In addition, it outperforms more traditional competing materials such as copper, aluminum, and carbon steel. Now, let's take a look at the history of stainless steel.
Here is the content list:
l The invention of stainless steel
l A milestone in the history of stainless steel
In 1913, Harry Brearley of Sheffield, England, discovered "non-rusting" steel. Despite many previous attempts, Brearley is credited with inventing the first true stainless steel with a chromium content of 12.8%. He added chromium to molten iron to produce a metal that would not rust. Chromium is a key ingredient because it is resistant to corrosion. After this discovery, Sheffield itself became synonymous with steel and metallurgy.
Brearley made the discovery by accident while solving the corrosion problem on the inside surface of gun barrels for the British Army at the start of World War I.
After the initial discovery, further improvements in stainless steel occurred at a fairly rapid rate. In 1919, Elwood Haynes received a patent for martensitic stainless steel; Premature-hardened stainless steel was first discovered by William J. Kroll of Luxembourg in 1929; Duplex stainless steel was produced for the first time in 1930 at Avesta Steel Works in Sweden.
Over the years, people have come to recognize the remarkable properties of stainless steel. Below is a short timeline outlining some key moments in the history of stainless steel.
l Between 1919 and 1923, the use of stainless steel was adapted to the manufacture of Sheffield surgical scalpels, tools and cutlery.
l In the early 1920s, various combinations of chromium and nickel were tested. For stainless steel, "18/8" indicates the percentage of chromium and nickel in the steel.
l In 1925, stainless steel tanks were used to store nitric acid, thus demonstrating the corrosion resistance of this unique metal.
l In 1926, the first surgical implants made of stainless steel were performed.
l In 1928, the first stainless steel fermenter was used to brew beer, proving the hygienic properties of stainless steel. Since then, the metal has been widely used in the food and beverage industry.
l In the 1930s, the first stainless steel trains were built in the United States.
l In 1931, the first stainless steel airplane was born.
l By 1935, stainless steel kitchen sinks were in widespread use.
l The Type 430 stainless steel (ferritic chrome) is used to manufacture tape recorders with a diameter of 0.1mm.
l The first stainless steel underwater television camera was introduced in 1954.
l The first tidal power station with stainless steel turbine blades was built in France in 1966.
l In the 1980s, stainless steel was used to build the world's longest movable flood barrier on the River Thames.
l In 2010, global production of stainless steel reached 31 million tons.
l In 2010, China produced about 11 million stainless steel drum washing machines.
In the last 100 years, about 100 grades of stainless steel have been discovered and put on the market. These grades are divided into four major groups, namely martensite, ferrite, austenite, and diphase. Ferritic and martensitic stainless steels are magnetic, whereas austenitic stainless steels are non-magnetic. They also add different amounts of other alloying metals, such as nickel, titanium and copper. Carbon and nitrogen are also added to enhance the overall characteristics of stainless steel.
Today, China is the world's largest producer of stainless steel. The growth of stainless steel is likely to increase as the sustainability benefits of stainless steel become more widely known. Researchers have even found that coating stainless steel with a kind of bio adhesive can make it antibacterial, adding to its many benefits. Therefore, this innovative material has the potential to extend its applications into the next century and beyond.
The material model of the water cup liner refers to 304 stainless steel, which is fully known as austenitic stainless steel. 304 stainless steel is food grade stainless steel approved by the state, and is commonly used in stainless steel tableware. 304 stainless steel is a stainless-steel brand manufactured according to ASTM standard of the United States. 304 stainless steel has good corrosion resistance and heat resistance, and is widely used in tableware, water cup and other daily necessities.
In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. As a result, most cups are marked with 304, but illegal vendors cheat consumers.
316 stainless steel is better! 304 and 316 are austenitic stainless steel, with content of 16-18%. The difference is that the molybdenum content of 316 stainless steel is 2% higher, so the corrosion resistance of 316 stainless steel is better than 304 stainless steel, especially chlorine corrosion resistance.
In addition, the average nickel content of 304 stainless steel is 9%, while that of 316 stainless steel is 12%. Nickel in metal materials can improve the high temperature durability, mechanical properties and oxidation resistance of materials. Therefore, the content of materials directly affects the comprehensive properties of materials.
Cold rolled 304 stainless steel is a very common stainless steel with a density of 7.93g/cm3, also known as 18 / 8 stainless steel. Its metal products have the characteristics of high temperature resistance and good processing performance, and are widely used in industry, food, medical and other industries.
The most important elements in 304 are nickel and chromium, but they are not limited to these two elements. Specific requirements are determined by product standards. According to the general judgment in industry, as long as the nickel content is more than 8%, the chromium content is more than 18%, it can be regarded as 304 stainless steel.
304 stainless steel is the most widely used Cr Ni stainless steel. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping, bending and other hot working properties, without heat treatment hardening phenomenon (service temperature - 196 ℃ - 800 ℃). It is resistant to atmospheric corrosion. If it is industrial atmosphere or seriously polluted area, it needs to be cleaned in time to avoid corrosion.
People's reliance on stainless steel is far beyond imagination. Stainless steel is a very common product material in our daily life. For example, most of the pots and pans used in our daily life are made of stainless steel. Stainless steel has a wide range of applications, and there are many types of stainless steel products. Many people don't know what the ideal stainless steel sheets, coil and plate are. This article will use the basic information of these stainless steel products to answer your doubts.

The characteristics of an ideal stainless steel product.
Stainless steel plate is generally the general name of stainless steel plate and acid-resistant steel plate. It has high plasticity, toughness and mechanical strength. Stainless steel plate has high temperature oxidation resistance and is resistant to corrosion by acid, alkaline gas, solution and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free.
Stainless steel sheet is also a common stainless steel product. The ideal stainless steel sheet needs a smooth surface, high plasticity, toughness and mechanical strength, and resistance to corrosion by acids, alkaline gases, solutions and other media. In addition, according to the manufacturing method, stainless steel sheet is divided into two types: hot rolled and cold rolled.
Generally speaking, the dimensional accuracy of cold rolling stainless steel sheets is higher. At present, the thinnest steel strip of hot rolling can be about 0.78 mm, while cold rolling can roll metal aluminum foil of 0.007 mm.
The durability of stainless steel products is mainly reflected in the high corrosion resistance, which makes it suitable for use in harsh environments. It needs to have fire and heat resistance, can resist fouling and maintain strength at high temperatures.
Various defects such as scratches, pits, sand holes, dark lines, creases, pollution, etc., will inevitably appear in the production process of stainless steel sheets, so that their surface quality, but these defects such as scratches and creases are high-grade materials. It is not allowed, so no scratches on the outside is also the basic requirement of stainless steel products.
The flexibility of stainless steel products is mainly reflected in its complete specifications and diverse materials. Every stainless steel product needs to go through a strict process to ensure its high dimensional accuracy.
