630 17-4PH 1.4542 X5CrNiCuNb16-4 Stainless Steel Round Bar Solution Treated
TYPE 630, 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 short time,
low temperature heat treatments that minimize warpage and scaling.
