17-7 PH is a precipitation-hardening stainless steel which combines high strength and hardness. Popular in Aerospace. 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.
17-7PH Stainless Steel 17-7stainless steel( 631 ) is a chromium-copper precipitation hardening stainless steel material used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius). 17-7PH Stainless Steel - peninsulaspringDue to its precipitation hardened quality 17-7 PH stainless steel is a highly formable stainless steel alloy that provides minimum distortion upon heat treatment, improved strength and hardness over other steel alloys, excellent fatigue properties, good corrosion resistance, and good formability. In high-heat treated conditions, 17-7 stainless steel sheet possesses excellent
Introduction. Overview. 17-7PH Austenitic-martensitic precipitation hardening (PH) stainless steel was developed based on 18-8CrNi stainless by adding Aluminum (Al) content. Al is added for deoxidizing and grain refining in steels. 17-7PH stainless steel (SUS 631) features better corrosion resistance than general martensitic stainless steel and higher strength than 17-7PH( grade 631 Stainless steel ) plates and sheets for sale17-7Ph is a type of Austenitic-Martensite precipitation hardened stainless steel developed base on 18-8CrNthats 631 stainless steel. After solid solution treatment, stainless steel 17-7ph will become unstable Austenite tissue, then cooling to precipitate carbide, and then Martensite transformation will be conducted.
SUS631 ( 17-7PH ) 632J1( 15-7PH ) and TOKKIN 350 (AM350 ) are cold rolled and then precipitation hardened. This process forms an intermetallic compound containing minute amounts of aluminum in the martensite, which enables these Precipitation Hardening Stainless Steels (SUS631,632J1 SUS631 ( 17-7PH ) 632J1( 15-7PH ) and TOKKIN 350 (AM350 ) are cold rolled and then precipitation hardened.

PH Stainless Steel Grades. Precipitation Hardening (PH) stainless steels are classified as martensitic or semi-austenitic. They develop their high strength and hardness through a variety of heat treatments resulting in a very high strength-to-weight ratio. Semi-austenitic grades are 17-7 PH ® and PH 15-7 Mo ®. They are austenitic in the Stainless Steel - Precipitation Hardening - 1.4542 (17/4 Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, ium, Niobium, and Molybdenum. The most well known precipitation hardening steel is 17-4 PH. The name comes from the additions 17% Chromium and 4% Nickel. It also contains 4% Copper and 0.3% Niobium. 17-4 PH is also known as stainless steel grade 630.
AMS 5529 is a solution heat-treated and cold rolled sub-type specification of Stainless Steel 17-7PH which is a semi-austenitic precipitation hardening steel with high levels of Chromium and Nickel. Main qualities of AMS 5529 are high strength and hardness, excellent fatigue properties, minimal distortion upon heat treatment, good formability in the annealed condition, and good Stainless Steel 17-7PH Strip Precipitation Hardening Type 17-7PH® Precipitation Hardening Alloy is a semi-austenitic stainless steel which is austenitic in the annealed condition, but martensitic in the hardened condition. Type 17-7PH® provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment.
17-7PH Stainless Steel is a semi-austenitic precipitation hardening steel with high levels of Chromium and Nickel. It is characterized by high strength and hardness, excellent fatigue properties, minimal distortion upon heat treatment, good formability in the annealed condition, and good corrosion resistance. Stainless Steel Spring Wire Explained Why Use Stainless 17-7PH has the addition of aluminum which precipitates out of the steel during the heat treat process, giving the steel:o additional strength o potential gain in tensile strength of 30,000+ PSI; Grades 304, 321, 347. Austenitic (Cr-Ni) grades of stainless:Cannot be hardened by heat treat. Instead, they are hardened by cold working or drawing
17-7 PH® is a chromium-nickel-aluminum precipitation hardening stainless steel that provides high strength and hardness and a moderate level of corrosion resistance up to 600F. What Is Precipitation Hardening Stainless Steel? - Clinton Jul 27, 2020 · What applications commonly rely on precipitation hardening stainless steel?
