Stainless steel plate is generally stainless steel plate and acid resistant 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 laid an important material technology foundation. There are many kinds of stainless steel plate, different performance, it has gradually formed a few categories in the development process. Austenitic stainless steel plate, martensite stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferrite two-phase stainless steel plate and other four categories. Stainless steel keeps the surface clean, so it conducts heat better than other metals with higher thermal conductivity. The surface of stainless steel plate is bright and clean, with high plasticity, toughness and mechanical strength, resistant to corrosion of acid, alkali gas, solution and other medium. It is an alloy steel that does not rust easily.
