Stainless Steel is one of the most versatile materials in the market that offers some of the highly good mechanical properties and specifications. The steel alloy has slight content of chromium present in it that provides excellent resistance to corrosion and excellent strength in high temperature applications. Presence of other chemical components in the steel offers other good properties. Elements such as carbon, niobium, phosphorous, manganese, and molybdenum are present in Steel that offers good mechanical properties and characteristics. There are several grades available in the market that is used in manufacturing good quality SS products. But one of the highly used materials in the market for manufacturing SS plates is grade 420.

SS 420 grade is widely used in industrial applications due to its good characteristics. The grade contains good quality of vanadium, sulfur, and molybdenum in their composition. Martensitic stainless steels contain high carbon content and manifest right hardness characteristic. Certain steels are frequently fabricated using methods that require hardening and tempering treatments. The operating circumstances of martensitic steels are affected by the loss of material’s strength at high temperatures and a decrease in extensibility at negative temperatures. The SS 420 PLATES exhibits excellent corrosion resistance, oxidation resistance, pitting resistance, good ductility, malleability, and excellent weldability.
