Material 1.4016

Stainless steel

The corrosion resistance of 1.4016 is lower than that of stainless austenitic grades.  But due to its ferritic microstructure, 1.4016 is resistant to the effects of stress corrosion cracking. However, the use of 1.4016 is limited by its poor weldability.

Heat Treatment

The heat treatment that makes this steel particularly soft consists of holding at temperatures between 750 °C - 850 °C followed by air cooling. 850 °C must not be exceeded, as this grade is sensitive to embrittlement due to grain growth.

Weldability

  • 1.4016 is difficult to weld
