N360 / 1.4108
N360 / 1.4108: High-Hardness, Corrosion-Resistant Martensitic Stainless Steel
Properties of N360 / 1.4108
N360 / 1.4108 is a martensitic stainless steel produced via a pressure electroslag remelting (P-ESR) process. This advanced metallurgy results in significantly improved corrosion resistance and compressive strength compared to conventional Cr or CrMo steels:
- Excellent corrosion resistance
- High hardness and compressive strength (up to 60HRC)
- Outstanding wear resistance
- Excellent polishability
Applications of N360 / 1.4108
Typical applications:
- Aerospace industry (e.g. high-load bearing components)
- Medical technology (e.g. surgical instruments)
- Pharmaceutical and food processing (e.g. hygienic components)
- Plastics industry (e.g. wear-resistant tooling)
- Precision mechanics (e.g. ball screws, rolling bearings)
