AISI 420A EN 1.4021 DIN X20Cr13 stainless steel sheet
AISI 420A, EN 1.4021, DIN X20Cr13, JIS SUS420J1 stainless, a rustproof, hardenable stainless chromium steel
alloy whose corrosion resistance can only be achieved by tempering its parts.
For an optimum corrosion resistance parts must be well polished.
Due to its low sulphur and carbon content, 1.4021 stainless quality is more corrosion resistant than high carbon stainless 1.4034 or 1.4035.

Other than AISI 420A stainless, we also provide the whole group of Type 420 martensitic stainless steel family.
Martensitic stainless steels are high carbon high chromium alloy steels.
They have been developed for ready processing and a range of applications after cold rolling.
Typical applications of our martensitic stainless steels include:
- razor blades
- surgical knives
- scissors
- cutlery
- pressure diaphragms
- valve components
- bacon slicers
- circlips
