17-4 PH® alloy is a martensitic precipitation-hardening stainless stee with Cu and Nb/Cb additions, 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 short-time, low-temperature heat treatments that minimize warpage and scaling. This versatile material is widely used in theaerospace, chemical, petrochemical, foodprocessing, paper and general metalwork-ing industries.
