What is 17 7PH stainless steel?

What is 17 7PH stainless steel?

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.

What is the chemical composition of 17 7PH stainless steel?

The chemical composition of 17-7 breaks down as follows: Chromium: between 16.0 and 18.0 percent. Nickel: between 6.50 and 7.75 percent. Aluminum: between 0.75 and 1.50 percent.

Is 17-4 PH 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. 17-4PH combines high strength and hardness with good corrosion resistance.

Does 17 4PH work harden?

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. Heat treatment in the 900°F (482°C) range produces the highest strength.

What kind of stainless steel is 17-7 pH?

17-7 Phis a precipitation-hardening stainless steel. 17-7 Ph offers good corrosion resistance, good formability, and high strength therefore has been used for aerospace applications. 17-7 PH is a registered trademark of AK Steel.

When to use ch900 on 17-7 pH wire?

CH900 applies to 17-7 PH (Type 631) wire that has been previously solution annealed and then cold drawn, which is then aged for 1 hour at 900 °F (482 °C). If your article has not been cold drawn, then CH900 cannot be performed.

What kind of corrosion resistance does 17-7 pH have?

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 600˚F.

When to apply ch900 to stainless steel wire?

CH900 applies to 17-7 PH (Type 631) wire that has been previously solution annealed and then cold drawn, which is then aged for 1 hour at 900 °F (482 °C).
