Steel containing more than 12.5% chromium in steel, with a high resistance to external media (acid, alkali salt) corrosion of steel, called stainless steel. According to the structure of the steel, stainless steel can be divided into martensitic, ferritic, austenitic, ferritic-austenitic, precipitation-hardened stainless steel, according to the national standard GB3280-92, a total of 55 provisions.

Plasma cutting is the most common method for cutting all grades of austenitic stainless steel with a thickness of more than 25mm. The design of the plasma gun significantly improves accuracy and incision quality, making it an ideal process for cutting straight lines or special shapes.

U.S. industrial recovery attracts foreign investment. For example, Sasol, a South African company, has begun production of the world's first ethylene tetramerization plant in LakeCharles, Louisiana. The shale revolution in the US has reduced the power of the petrochemical and refining industries in Latin America to set prices.

At present, the market competition pattern of the global stainless steel industry is very complex, mainly including Europe, Asia, the Americas and Oceania and other regions.

Stainless steel, on the other hand, is a reliable guarantee of strong material choice for heavy offshore installations. The metal's inherent corrosion resistance provides a high strength-to-weight ratio for infrastructure, even in Marine and coastal environmental conditions.

In addition, like a batch of stainless steel wire, made into a straight branch, no obvious magnetic sensation, but when it is bent into a rectangle or circle, some magnetism is generated due to the large cold bending deformation, especially the magnetism of the corner part is more obvious.

However, with the improvement of the production process and technology of many large calender plants, the gap between positive and calender materials is slowly narrowing, and some imitation positive plates can even be fake and real, requiring professionals with rich experience to distinguish.

The continuous growth of electricity demand has injected strong impetus into the "steel demand". According to industry analysts, with the continuous growth of domestic "electricity demand", the demand for power steel is also increasing.
