What is 17 7PH stainless steel?
A stable, chromium-nickel-aluminum steel, 17-7 is a precipitation hardening steel with a high strength and moderately resistant to corrosion. In terms of corrosion resistance, 17-7 PH is comparable to 304 stainless steel and a better choice when compared to the 400 series of stainless steel.
What are the physical properties of 17 7PH stainless steel?
Stainless steel grade 17-7 PH is a precipitation hardened stainless steel that possesses high strength and hardness, excellent fatigue properties, good formability, good corrosion resistance, and minimal distortion upon heat treatment. The properties of this alloy are well suited for aerospace applications.
Is 17 4PH a stainless steel?
Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. The corrosion resistance of Alloy 17-4PH is comparable to 304 stainless steel in most environments, and is generally superior to the 400 series stainless steels.
What is the source of high strength in 17 7PH steel?
heat treatment
17-7PH is known for its ability to gain higher strength through heat treatment, similar to martensitic grades.
