1.4542 / AISI 630 / 17-4PH® is a martensitic chromium-nickel-stainless steel, stabilized with niobium. 1.4542 17-4PH Stainless Steel-Precipitation Hardening 17-4PH is a chromium-nickel grade of stainless that may be hardened by a single low temperature precipitation-hardening heat treatment. Excellent mechanical properties at a high strength level may be obtained by such treatment. Scaling and distortion is minimized. 17-4PH should not be used in the solution treated condition.
May 13, 2008 · 17-4 stainless steel is a martensitic, precipitation-hardening stainless steel. At the solution treating temperature, 1900°F (1040°C), the metal is austenitic but undergoes transformation to a low-carbon martensitic structure on cooling to room temperature. This transformation is not complete until the temperature drops to 90°F (32°C). 17-4 PH H1150 Bar - Precipitation Hardening Stainless 17-4 PH is a martensitic precipitation hardening stainless steel with additions of copper (Cu), niobium (Nb) and tantalum (Ta). The grade combines high strength and hardness values with moderate corrosion resistance. Different heat treatment temperatures can optimize mechanical properties, e.g. yield strength at 1100 1300MPa. 17-4 PH stainless steel Desktop MetalAbout 17-4PH Stainless Steel 17-4 PH is a martensitic precipitation - hardened stainless steel.
Description. 17-4PH grade steel is a precipitation hardening stainless steel with excellent corrosion resistance, superior to martensitic grades such as 431 and 410, and comparable to austenitic grade 304. It is heat treated by age hardening and has the potential for very high strengths (between 40-47HRc in the H900 condition). 17-4PH Stainless Steel-Introduction, Applications, Data SheetOverview 17-4PH is a precipitation hardened (PH) martensitic stainless steel consisted of copper and niobium/tantalum. This grade features high strength, hardness and corrosion resistance. Its mechanical properties can be optimized by heat treatment with the compression strength achieving up to 1100-1300 mpa (160-190 ksi).

Casting Material:Precipitation-Hardening Stainless Steel 17-4PH Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance. 17-4 is a common named used by two or more producers, not a Martensitic stainless steel and precipitation hardening Precipitation hardening stainless steels provide remarkable levels of high strength and hardness in a very wide range. With the exception of the martensitic alloys (e.g. Dura 17-4PH / EN 1.4542) cold formability is satisfactory. Precipitation hardening grades have higher alloying contents than martensitic steel grades. Precipitation Hardening Stainless Steels Stainless Steel 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 annealed state, and martensitic in the hardened condition.
Apr 22, 2005 · 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 steels grade 630. Precipitation hardening:Stainless steels - Solution and Precipitation hardening:Stainless steels Specialty Stainless Steel Processes (S 3 P) There are a multitude of cast and wrought stainless steel alloys that can have various desirable characteristics enhanced by either solution treating or by solution treating and precipitation age hardening. 17-4PH and Ph13-8Mo. Precipitation age hardening. Specification Sheet:Alloy 17-4PH - Sandmeyer SteelAlloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance.
