Precipitation hardening 15-5 PH , EN 1.4545 , DIN X5CrNiCu15-5 stainless steel round bars
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.
