AISI 420 stainless steel - 1.4028 - Available from stock
Z30C13 stainless steel is a martensitic steel grade as per the EN 10088-3 standard, which isequivalent to the AISI 420 American standard. It is characterised by its relatively high carbon content, giving it a certain hardness and resistance following heat treatment.
Technical summary of this steel:
- Europe: Z30C13 - X30Cr13 - 1.4028
- USA: AISI 420 - S42000
- Europe: EN 10088-3 | NF S 94-090
- USA: ASTM F899
- Corrosion resistance: in fresh water, it is highly resistant to natural oxidising agents and certain dilute acids thanks to its chromium content.
- Oxidation resistance at high temperatures: capable of withstanding oxidation at high temperatures, making it an appropriate choice for certain high-temperature applications.
- In order to reach full hardness and improve corrosion resistance, the Z30C13 needs to be quenched and then tempered.
- Quenching means heating the steel to a high temperature and then quickly letting it cool, whereas tempering modifies the steel’s final mechanical properties.

- Quenching means heating the steel to a high temperature and then quickly letting it cool, whereas tempering modifies the steel’s final mechanical properties.
Special advantages
Conclusion
Application
- The Z30C13 is a cost-effective option for applications that need both corrosion resistance and hardness, especially in less hostile environments, or for tools and components that need to keep a sharp cutting edge.
- Used in applications that require good corrosion resistance and a high level of hardness, such as knives, surgical instruments and some mechanical parts.
- Suitable for environments where temperatures can get high, but not extreme enough so as to require the use of superalloys.
