High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius).General PropertiesStainless steel Alloy 17-4 PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F / 300°C), and corrosion resistance.Mechanical properties can be optimized with heat treatment. Very high yield strength up to 1100-1300 MPa (160-190 ksi) can be achieved.The grade should not be used at temperatures above 572°F (300°C) or at very low temperatures. It has adequate resistance to atmospheric corrosion or in diluted acids or salts where its corrosion resistance is equivalent to Alloy 304 or 430.Chemistry Data :  Carbon0.07 maxChromium15 - 17.5Copper3 - 5IronBalanceManganese1 maxNickel3 - 5Niobium0.15 - 0.45Niobium+Tantalum0.15 - 0.45Phosphorus0.04 maxSilicon1 maxSulphur0.03 max
