AISI 420A EN 1.4021 Stainless Steel Sheets And Coils
Martensitic stainless steel, It is a hardenable stainless steel used for its basic corrosion resistance,
high strength and wear resistance.
Martensitic stainless steels are high carbon-chromium steels.
They have been developed for ready processing and a range of applications after cold rolling.
Our product range includes steels with improved corrosion resistance.
This grade combines the following characteristics:
- Basic corrosion resistance
- High hardness and strength
- Controlled balance of mechanical properties by hardening and tempering
- High wear resistance
- Cost effectiveness due to low chromium content and absence of nickel
- Magnetic
- Thermal expansion comparable to carbon steel
- Not easy to weld
Typical applications of our martensitic stainless steels include:
- razor blades
- surgical knives
- scissors
- cutlery
- pressure diaphragms
- valve components
- bacon slicers
- circlips
