How can you tell real stainless steel coil

With the development of industrial technology, there are more and more types of stainless steel. Due to the many types of stainless steel, included in the standard grades, while there are still a large number of widely used non-standard grades, the performance of these grades vary, while there are still a large number of widely used non-standard grades, the performance of these grades vary, so just the right choice of applicable stainless steel grades is very difficult. At the same time, many people do not know how to identify the real stainless steel products, this article will give the audience a simple knowledge by introducing the selection of stainless steel coils.

• How can you tell real stainless steel coil?

• The characteristics of real stainless steel coil.

• The market demand for stainless steel coils.

How can you tell real stainless steel coil?

Observe the surface of the stainless steel

Look at the surface to see if it is bright and clean, with or without rust spots. Raw material surface defects. Such as scratches, pockmarks, over pickling, etc. The hardness is too low, the surface is prone to orange peel phenomenon when deep drawing, after deep drawing of the product, the deformation is extremely large area of the surface out of small black dots. This stainless steel material must have quality problems.

Specific steps

The easiest way to identify stainless steel is to dissolve 8g CuSO4 in 100ml distilled water, then add 3 drops of concentrated sulphuric acid, drop this solution on the stainless steel products to keep 6min, the real rusty steel system will not change, otherwise a layer of copper will be deposited on the surface of the steel. At the same time, the way to identify the real stainless steel or judge whether it is magnetic, this is because the stainless steel range is large, many types, some can suck, some can not, mainly to see whether the steel contains iron, nickel, cobalt, if there is then can suck, otherwise can not.

The above is the main basis for identifying real and fake stainless steel rolls. The market to buy stainless steel products whose material composition is mostly not in line with national standards of stainless steel. The real stainless steel coil has a good performance in terms of both quality and appearance. The next part of this article will explore the characteristics of the real stainless steel coil.

The characteristics of real stainless steel coil.

Stainless steel coil has high plasticity, toughness and mechanical strength and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, provided that the stainless steel coils are regularly maintained and cleaned. In addition, stainless steel coil is a qualitatively strong product with a wide range of applications in medical appliances, building materials, chemicals, food industry, agriculture and other fields.

The market demand for stainless steel coils.

In recent years, China's stainless steel industry has been developing rapidly and continuously, becoming one of the fastest growing and most consuming countries in the world, thus attracting more widespread attention from the industry. With the continuous development of industrial technology, there are more and more types of stainless steel, which is also the number of stainless steel coils is increasing. Stainless steel coil with its unique corrosion resistance, high temperature resistance, high strength, fine surface, can be recycled rate and other unparalleled good performance by the majority of enterprises. It is expected that in the future, the market demand for stainless steel coil will be further enhanced.
