Mechanical Properties: 420S45 has excellent strength, hardness, and wear resistance, making it suitable for applications where high cutting performance and durability are required. It also offers good corrosion resistance, but not as superior as the 300 series stainless steels.
Technical Properties: 420S45 has a higher carbon content compared to the 300 series stainless steels, which contributes to its superior hardness and edge retention. It is also magnetic and can be hardened through heat treatment, unlike austenitic stainless steels.
Chemical Composition: The chemical composition of 420S45 includes about 0.36-0.42% carbon, 1% manganese, 1% silicon, and 13-14% chromium. This composition gives it a good combination of corrosion resistance, hardness, and strength.
In conclusion, the 420S45 steel grade is distinguished by its high carbon content, which provides superior hardness and wear resistance compared to other stainless steel alloys. However, it may not offer the same level of corrosion resistance as the 300 series stainless steels.
