SUS630 Cold Rolled Stainless Steel Strip In Coil ASTM A693 17-4PH
Martensitic precipitation/age-hardenable stainless alloy 630, 17-4PH, 1.4542, X5CrNiCuNb16-4 offers
high strength and hardness, excellent corrosion resistance, and good fabricating characteristics.
Precipitation hardening steel 17-4PH is the most widely used of all the precipitation-hardening stainless steels.
Its valuable combination of properties gives designers opportunities to add reliability to their products
while simplifying fabrication and often reducing costs.
Applications
- Oil field equipment
- Chemical process equipment
- Fittings
- Pump shafts
- Gears
- Paper mill equipment
- Aircraft parts
- Flanges and valves
17-4PH is a martensitic precipitation-hardening stainless steel 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.
