– 420S45 steel has excellent corrosion resistance and hardness, making it ideal for high-performance blades and cutting tools.
– It has good strength and toughness, allowing it to retain its sharp edge and withstand heavy use without chipping or deforming.
– 420S45 steel also has good wear resistance, ensuring a long service life for blades and cutting tools.
Technical Properties:
– 420S45 steel has a high carbon content, typically around 0.15% to 0.60%, which contributes to its hardness and wear resistance.
– It also contains chromium (12-14%) which provides excellent corrosion resistance, important for tools that may be exposed to moisture and harsh conditions.
– Additionally, 420S45 steel can be heat treated to further enhance its mechanical properties, such as increasing hardness and strength.
Chemical Composition:
– The chemical composition of 420S45 steel typically includes carbon, chromium, manganese, silicon, phosphorus, sulfur, and iron.
– The high carbon and chromium content are particularly important for its performance as a blade and cutting tool material, providing the hardness and corrosion resistance needed for these applications.
