AISI 630 EN 1.4542 S17400 17-4PH Stainless Steel Round Bars
AISI 630 EN 1.4542 S17400 17-4PH Stainless Steel Round Bars
630 is a precipitation hardening Cr-Ni-Cu stainless steel,
Martensitic precipitation hardenable stainless steel.
High strength, good overall corrosion resistance, and oxidation resistance in continuous
service to 1200° F (650° C) a good combination of high strength corrosion resistance,
and is often the best solution of stainless steel when high strength is required.
Parts machined from solution treated bar stock should be heat treated or aged prior to use.
Applications like Parts for service under high stress in corrosive environment.
Valves in the oil industry, turbine valves, propeller shafts, tie rods, turbine blades, gear, bolts,
springs, supporting cables for seawater structures.
