EN 1.4005 vs. EN 1.4006 stainless steel: Heat Treatment and Hardness
1.4005 (416) stainless steel :
Annealed Hardness: ~170 HB
Hardened by: Quenching and tempering
Max Hardness: ~240 HB (~HRC 22–25)
Note: Often supplied in the annealed condition due to focus on machinability
1.4006 (410) stainless steel:
Annealed Hardness: ~170 HB
Hardened by: Quenching from 925–1010°C, then tempered
Max Hardness: Up to ~500 HB (~HRC 50)
Note: Capable of high hardness and wear resistance in tempered conditio
In the automatic lathe industry: EN 1.4005 Vs. EN 1.4006 Stainless Steel: Which One To Choose?
If you focus on processing efficiency, especially high-speed lathes or automatic lathes, choose 1.4005 stainless steel. If you need strength, heat treatment performance or moderate corrosion resistance, choose 1.4006 stainless steel. Since 1.4005 is prone to sulfur embrittlement, it should be avoided in welding or highly corrosive environments.
