1.4545 Stainless Steel Round Bar 15-5PH Polished Round Bar S15500 Forged Round Bar

Type 15-5 PH 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.

Type 15-5 PH is the ferrite-free version of Type 17-4 PH stainless steel.
Both alloys are widely used in the aerospace, chemical, petrochemical, food processing, paper and

general metalworking industries.
