Material Description
17-4 PH is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel. 17-4 PH stainless steel is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening. Its valuable combination of high strength, good corrosion resistance and toughness in both base metals and welds gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. High strength is maintained to approximately 316°C (600°F). This material has good resistance to stress corrosion cracking in the lower strength conditions.
Material Properties High strength and toughness High corrosion resistance Can be highly polished | Applications Aerospace applications Fasteners Base plates Chemical processing equipment Petroleum refining equipment Nuclear components Food grade stainless steel for processing equipment General metalworking applications that call for precipitation-hardening stainless steel |
