Characteristics of stainless steel plate

Stainless steel plate is widely used, with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; It has good hot workability such as stamping and bending, no heat treatment hardening phenomenon and fatigue performance. Without surface treatment, this index of maraging steel is close to that of other ultra-high strength steels, but maraging steel can obtain very high surface hardness and fatigue limit through simple shot peening or nitriding treatment. Compared with other ultra-high strength steels, maraging steel has excellent comprehensive welding properties, and generally will not produce welding cracks even without welding preheating and post heating.

There are dust containing other metal elements or attachments of dissimilar metal particles on the surface of stainless steel. In humid air, the condensate between the attachments and stainless steel connects them into a micro battery, which leads to electrochemical reaction and damage to the protective film, which is called electrochemical corrosion. Organic juice adheres to the surface of stainless steel and forms organic acid in the presence of water and oxygen. For a long time, the corrosion of organic acid on the metal surface will be. The surface of stainless steel contains acid, alkali and salt substances, causing local corrosion. In polluted air, sulfuric acid, nitric acid and acetic acid liquid points are formed in the presence of condensate, causing chemical corrosion. The above conditions can cause the damage of the protective film on the surface of stainless steel and lead to corrosion.
