Technological properties

Application areas

This austenitic grade is used for applications requiring complete non-magnetisability, a high wear resistance and maximum corrosion resistance.

Corrosion properties

Besides having a high wear resistance, this alloy is extremely resistant to corrosion and scaling, as well as highly tempering-resistant. This corrosion resistance is at its best with finely ground or polished surfaces.

General machinability

In as-delivered condition, this material can be machined by conventional methods.

Heat Treatment

Solution Anealing: 1200°C, 2 hr in vacuum (Cooling 4 bar N2) Hardness: 52 HRC - Age-Hardening 800°C, 6 hr in Vacuum, Hardness: 54 HRC
