ABSTRACT:
A cavitation resistant, low carbon 12% chromium steel alloy utilizing a nominal 1.5% copper addition which imparts strength by a precipitation reaction. The alloy exhibits a higher strength and hardness for a given carbon content and conversely is less susceptible to casting and welding cracks and stress corrosion cracking.
