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
