1.4545 UNS S15500 XM-12 15-5PH Precipitation Hardening Stainless Steel
1 1.4545 Introduction:
15-5PH is a martensitic precipitation-hardening stainless steel that provides 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.
15-5PH is the ferrite-free version of 17-4PH Stainless Steel. Both alloys are widely used in the
aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
2 1.4545 Applications:
Aircraft components
High pressure corrosive fabricated parts such as valves
Shafts
Fasteners
Fittings and gears
3 Quality Standard:
ASTM A564 2004 Standard Specification for Hot Rolled and Cold Finished Age Hardening Stainless Steel Bars and Shapes
ASTM A705 Standard Specification for Age Hardening Stainless Steel Forgings
