1.4542 is a martensitic precipitation/age-hardening stainless steel offering high strength and hardness along with excellent corrosion resistance. It has good fabricating characteristics and can be age hardened by a single-step, low temperature treatment. It has high strength combined with good corrosion resistance in fresh and salt water, industrial and marine atmosphere, and in oxidizing chemicals. 1.4542 shows excellent resistance to oxidation up to approximately 539C.
It has been used for a variety of applications including oil field valve parts, chemical process equipment, aircraft fittings, fasteners, pump shafts, nuclear reactor components, gears, paper mill equipment, missile fittings, and jet engine parts.

Heat to 1025-1055oC, then air or oil cooling. This will produce a maximum Brinell hardness of 363.
Temperature 480-620oC, then air cooling. Hardness after precipitation hardening is 42-32 HRC.

Hot forming temperature: 1100-900oC.
Despite its high initial yield strength, 17-4 can be cold worked successfully by most common methods.
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening.
1.4542 has withstood corrosive attack better than any of the 400 series hardenable stainless steels, and, in most corrodents, its corrosion resistance closely approaches that of stainless types 302 and 304.
1.4542 can be satisfactorily welded by the shielded fusion and resistance welding processes. Oxyacetylene welding is not recommended, since carbon pickup in the weld may occur. When a filler metal is required, AWS E/ER630 welding consumables should be considered to provide welds with properties matching those of the base metal. When designing the weld joint, care should be exercised to avoid stress concentrators, such as sharp corners, threads, and partial-penetration welds. When high weld strength is not needed, a standard austenitic stainless filler, such as E/ER308L, should be considered.
