17 4 ph stainless steel hardness chart.
17 4 ph stainless steel 2 as supplied from the mill in condition a 17 4 ph stainless steel can be heat treated at a variety of temperatures to develop a wide range of properties.
As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress.
High strength 17 4 ph stainless steel with a higher chromium content than 15 5 ph stainless steel this high strength 17 4 ph offers better corrosion resistance.
In addition it is more cost effective than many high nickel non ferrous alloys.
In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels.
