Can 17-4 be hardened?

Properties. 17-4 can be heat treated to high levels of strength and hardness, and features corrosion resistance and machinability comparable to austenitic 304 stainless. Being martensitic, 17-4 is magnetic. 17-4 is capable of being hardened up to approximately 44 Rc when heat treated to condition H900.

What is the condition for 17-4 PH?

17-4 PH Condition A. 17-4 PH 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. 17-4 PH should not be used in the solution treated condition.

Is 17 4 PH stainless steel corrosion resistant?

Corrosion Resistance: 17-4PH Stainless Steel has excellent corrosion resistance. Corrosion tests and service experience have shown that in all aged conditions it is superior to standard hardenable stainless grades such as 420, 431 and 410 stainless.

What is the ASTM standard for 17 4 pH?

Comparable standards: UNS17400 Type 630 ASTM A564 Type 630. 17-4PH is a precipitation-hardening martensitic stainless steel, which combines high strength and hardness (after heat treatment) with excellent corrosion resistance, and is suitable for easy fabrication.

What is 17-4PH steel?

17-4PH is a precipitation-hardening martensitic stainless steel, which combines high strength and hardness (after heat treatment) with excellent corrosion resistance, and is suitable for easy fabrication. Solution Treatments: As supplied 17-4PH, is usually in the solution treated condition, (Condition A).
