Mechanical properties:
– 420S45 steel has a higher hardness and wear resistance compared to 304 and 316 stainless steel, making it ideal for applications such as cutting tools, surgical instruments, and mechanical components.
– It also has better toughness and impact resistance compared to 440C stainless steel, making it suitable for applications that require both high hardness and toughness.
Technical properties:
– 420S45 steel has good corrosion resistance in the hardened and tempered condition, making it suitable for applications in mildly corrosive environments.
– It can be heat treated to achieve even higher hardness and strength, providing versatility in various applications.
Chemical composition:
– 420S45 steel contains higher carbon content (0.45%) compared to 304 (0.08%) and 316 (0.08%) stainless steel, contributing to its high strength and hardness.
– It also contains a moderate amount of chromium and other alloying elements, providing good corrosion resistance and hardenability.
Overall, the unique combination of mechanical properties, technical properties, and chemical composition sets 420S45 steel apart from other stainless steel grades, making it a suitable choice for applications that require high strength, hardness, and wear resistance.
