17-4PH is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength,
good corrosion resistance, good mechanical properities 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.
