P/M 625 is a prime candidate for critical service parts used in deep sour gas wells and other highly corrosive environments where strength is a prerequisite. Consider P/M 625 for use in the chemical process, pulp and paper, and nuclear industries as well. It maintains excellent corrosion resistance in a variety of hostile environments (such as phosphoric acid, organic acids, and sea water). It is available at yield strengths from 60 ksi (414 MPa) to 120 ksi (828 MPa), with no sacrifice in corrosion resistance. P/M 625 also exhibits excellent resistance to stress corrosion cracking, pitting, and intergranular attack
Advantages:
Near net shape
Excellent corrosion resistance
Heat treatment for superior strength
Flexibility in design

P/M Duplex and Super Austenitic Stainless Steels -
view pdf |
Crucible's P/M Stainless Steels provide the superior properties needed for demanding applications in a wide variety of industries. Crucible P/M stainless steel components are made from nitrogen-atomized powder, consolidated by hot isostatic pressing (HIP) or hot extrusion, and offer many advantages over cast or forged stainless components. HIP ensures fully dense equiaxed microstructure with no porosity, flow lines or ther detrimental features commonly associated with castings or forgings.
Advantages:
Fully dense components
Fine grain, equiaxed microstructure
Uniform properties regardless of test direction or section thickness
Near net shape technology maximizes material use and minimizes machining
