Precipitation Hardening Stainless Steel

These grades offer reasonable corrosion resistance with extremely high strengths and hardness values obtained through heat treatments. The overall corrosion resistance of these materials is superior to most martensitic stainless steels but not as good as standard austenitic stainless steels.

Alloy Properties
Representative Alloys	CB7Cu-1 and CB7Cu-2.
Applications	For high-strength requirements (to 175 KSI); a superior combination of strength, toughness and weldability with moderately good corrosion resistance
Limitations	Should be used in an aged condition
Typical Uses	Structural parts requiring at least moderate corrosion resistance
Machinability	Good when in condition A (solutioned)
Weldability	Should be welded in soft condition, then re-solutioned and re-aged
Corrosion Resistance	Moderate to good
