420 Stainless Steel Strip
420 stainless steel strip is a high-carbon martensitic stainless steel known for its excellent hardness, wear resistance, and polishability. It provides good corrosion resistance in mild environments and is commonly used in cutlery, surgical instruments, and industrial tools. This grade is magnetic and suitable for heat treatment, making it ideal for applications requiring edge retention and strength.
Product Overview
420 stainless steel strip is a martensitic stainless steel known for its high strength, hardness, and wear resistance. It offers good corrosion resistance in mild environments and is magnetic in both annealed and hardened conditions. This grade is widely used in applications requiring moderate corrosion resistance and high mechanical properties.
