Bal

17-4 PH is a martensitic, precipitation-hardening stainless steel that provides an outstanding combination of high strength and hardness along with excellent corrosion resistance. 17-4 PH has good fabricating characteristics and can be age hardened by a single step, low temperature treatment. 17-4 PH is a versatile material widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.

Availability

17-4 PH is available in Bar, Wire, Forgings, Tube, Rings, Plate, Sheet and Strip. For all stock availability contact Sales.

Specifications

Type 17-4 PH Stainless Steel is covered by the following specifications:

AMS 5604 Sheet, Strip Cold Rolled and Plate.

AMS 5643 and 5622 Bars (Flat, Hex, Round, Square), Wire, Forgings, Tubing and Rings

ASTM A 693 Plate, Sheet and Strip

UNS: S17400

Corrosion Resistance

17-4 PH Stainless Steel withstands corrosive attack better than any of the standard hardenable stainless steels and is comparable to Type 304 in most media.

Formability

In Condition A, 17-4 PH is hard, therefore forming normally should be limited to mild operations. However, formability can be greatly improved by heat treating before cold working or by use of hot-forming methods.
