Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an alloy steel that does not easily rust, but it is not absolutely rustless.
The stainless steel sheet is divided into two types according to the method of hot rolling and cold rolling, including a thin cold plate with a thickness of 0.02-4 mm and a medium plate with a thickness of 4.5-100 mm.
In order to ensure that the mechanical properties of various types of stainless steel plates such as yield strength, tensile strength, elongation and hardness meet the requirements, the steel plates must be subjected to annealing, solution treatment, aging treatment, etc. before delivery.
Chemical composition:
C< = 0.030%, Mn< = 2%, Ni: 11 ~ 15%, Si: <= 1%, P: <= 0.045%, S< = 0.030%, Cr :18 ~20%, Mo: 3- 4%
The common size :
Cold rolled 317L ss plate: thickness: 0.3-3.5mm, Size: 1220*2440mm
Hot rolled 317L ss plate: thickness: 4-60mm, Size: 1500*6000mm
The corrosion resistance of stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and its internal structure. The main role of chromium is chromium.
