17-4 PH stainless steel round bars
17-4 PH ( 630 ) stainless steel round bars
17-4 PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength,
good corrosion resistance, good mechanical properties at temperatures up to 600°F (316°C), good toughness in both
base metal and welds, and shorttime, low-temperature heat treatments that minimize warpage and scaling.
This versatile material is widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
