17-4 PH - Stainless Steel
Stainless Steel 17-4 PH
Stainless Steel 17-4 PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strenght, good corrosion resistance, good mechanical properties at temperatures up to 600 °F (316 °C), good toughness, and short-time, low-temperature heat treatments that minimize warpage and scaling.
