SUS631 17-7PH Cold Rolled Stainless Steel Strip In Coil And Sheets
17-7 PH, 631, EN 1.4568, DIN X7CrNiAl17-7 is a precipitationhardening stainless steel that provides
high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability,
and minimum distortion upon heat treatment. The alloy provides valuable property combinations
particularly well suited for aerospace applications.
This special alloy also provides benefits for other applications requiring high strength
and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 600°F (316°C).
