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.

Type 316 is an austenitic chromium nickel stainless steel. It also contains molybdenum which increases its general corrosion resistance as well as the mechanical properties at elevated temperatures. The properties of type 316 are similar to type 304; however 316 is stronger at elevated temperatures amd also corrosion resistance is improved particularly against sulphates, phosphates and other salts as well as reducing acids such as sulphuric, sulphurous and phosphoric. Type 316L is an extra low carbon version of type 316.
Grade 316 is the standard molybdenum-bearing grade. It is excellent in a range of atmospheric environments and is generally more resistant that grade 304. 316 tends to be regarded as the standard “marine grade stainless steel”. It also has excellent weldability. Grade 316 is an incredibly versatile material, so as a result it has a wide range of uses.
