420 A / 1.4197 / X 20 Cr 13 martensitic hardenable stainless steel |
| |
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, this quality is more corrosion resistant than 1.4034 or 1.4035. This material is suitable for medical and dental technologies in the low quality range. |
