Material
Stainless steel strip for springs
EN101511.4310
EN10151 1.4310 is a stainless austenitic spring steel characterized by its high strength, good elasticity, and excellent corrosion resistance. It is commonly used in springs, clips, and thin sheet components where a combination of mechanical properties and environmental resistance is critical. The material contains chromium and nickel as primary alloying elements, providing its stainless properties.. It is widely applied in industries requiring long-lasting and reliable performance, such as automotive, medical devices, and consumer products. The closest AISI equivalent is AISI301.
