The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is not easy to rust, but it is not absolutely rust free. In order to ensure that the mechanical properties of all kinds of stainless steel plates such as yield strength, tensile strength, elongation and hardness meet the requirements, the steel plate must be annealing, solution treatment, aging treatment and other heat treatment before delivery.
