Material 17-4PH EN 1.4542 Stainless Steel Rods SUS630 Round Bars
Material 17-4PH EN 1.4542 Stainless Steel Rods SUS630 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.
Material 17-4PH is widely used in the aerospace, chemical, petrochemical, food processing, paper
and general metalworking industries.
