17-4 PH or UNS S17400 chromium-nickel-copper hardening stainless steel is extensively used for applications that require corrosion resistance and high strength.
17-4 PH stainless steel can develop its excellent hardness and strength with heat treatment. This stainless steel grade can provide toughness in both welds and base metals.
17-4 PH stainless steels exhibit excellent physical and mechanical properties of high strength, corrosion resistance, and hardness. Their high strength is often maintained to 600°F or 316°C. Mechanical properties in 17-4 grade are optimized through heat treatment.
This stainless steel grade should not be used at the very high temperature which is above 572°F (300°C) or even at very low temperatures. It can also have adequate resistance to stringent environments like diluted acids or salts and atmospheric corrosion where corrosion resistance is highly required. 17-4 can withstand corrosive attacks better than other standard hardenable steels.
This grade is known to provide a very outstanding combination of good corrosion resistance, mechanical properties, and high strength at high temperatures. Distortion and scaling of 17-4 bars are also minimized by low-temperature heat treatments.
A lot of standard heat treatments have been developed making 17-4 PH fit a wide variety of industrial applications:
