SS410 is a martensitic stainless steel that provides good corrosion resistance plus high strength and hardness.It is magnetic in both the annealed and hardened conditions.A wide range of properties can be developed with different heat treatments. Applications requirring moderate corrosion resistance and high mechanical properties are ideal for this alloy.Typical uses include flat springs,knives,kitchen utensils and hand tools.

MOQ 5 Tons Realted Products: Stainless steel wire rod,stainless steel pipe/tube,stainless steel flat bar,stainless steel angel bar... Corrosion Resistance: SS410 provides good corrosion resistance to air,water and some chemicals.It shows satisfactory resistance to nitric acid,concentrated sulfuric acid,concentrated sulfuric acid,dilute acetic acid and naptha.Resistance to food acids is good. Annealing: Annealing is achieved by heating to above 816℃ and 899℃for 90 minutes per 25mm thickness followed by air quenching.Controlled atmospheres are recommended in order to avoid excessive oxidation of the surface. Welding: The martensitic class of stainless steeks has limited weldability due to its hardnability.Special consideration is  required to avoid cold cracking by preheating to 260℃.Post-weld heat treatment should be considered to achieve required properties.This particular alloy is generally considered to have the best weldability of this stainless class.
