Sep 10, 2015 · Grade 17-4 stainless steel is the utmost extensively applied steel of the precipitation hardening grade steels. It has great toughness, high strength, and normal corrosion resistance. Precipitation hardening, also known as age hardening, is a heat treatment method utilized to augment the yield strength of this grade.
17-4 PH® Stainless Steel is the most widely used of all the precipitation-hardening stainless steels. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. This valuable alloy is widely used in the Understanding the Difference: 17-4 PH vs. 17-7 PH Precipitation Hardening Alloys When choosing an alloy for a particular project, it may be helpful to determine your criteria for use based on the strength, corrosion resistance, magnetic qualities and stability
17-7PH Precipitation Hardening. 17-7 PH contains 17% chromium, 7% nickel and 1% aluminum. It is a precipitation hardening steel capable of reaching very high strength and hardness without any loss of corrosion resistance. Surface scaling and distortion in heat treatment is eliminated by its ability to be treated at very low temperatures. MIL-S-25043 Steel Plate, Sheet, and Strip, 17-7 Ph, Corrosion Resistant, Precipitation Hardening (Superseded by SAE AMS-5528 or SAE AMS-5529)
17-7PH Precipitation Hardening Stainless Steel. 17-7 PH is a precipitation-hardening stainless steel which combines high strength and hardness. The alloy has excellent fatigue properties, good corrosion resistance and is easily formed. Due to the alloys good mechanical and physical properties, 17-7PH is particularly popular in the aerospace sector. 17-4 Stainless Steel – Precipitation Hardening Steels Safety Data Sheet according to the Hazard Communication Standard (CFR29 1910.1200) HazCom 2012 06/01/2015 EN (English) 4/8
