15-5 PH Stainless Steel is a martensitic precipitationhardening stainless steel that provides
an outstanding combination of high strength, good corrosion resistance, good mechanical properties
at temperatures up to 600 °F (316 °C) and good toughness in both the longitudinal and transverse
directions in both base metal and welds.
Short-time, low-temperature heat treatments minimize distortion and scaling.
15-5 PH STAINLESS STEEL offers a combination of high strength and hardness, good corrosion resistance plus
excellent transverse mechanical properties. 15-5 PH Stainless Steel is the ferrite-free version of 17-4 PH
Stainless Steel. Both alloys are widely used in the aerospace, chemical, petrochemical, food processing,
paper and general metalworking industries.

15-5 PH Stainless Steel is produced in sheet and strip.
Material is supplied in Condition A, ready for fabrication and subsequent hardening
by the user. Since the material transforms to martensite on cooling to room temperature,
flatness requirements should be considered and discussed as part of the order.
