Stainless Steel 15-5ph Fasteners

AISI 15-5ph Equivalent Grades

AISI 4130 Bolts

15-5ph Fasteners are manufactured in varieties of bolts, stud bolts, screws, threaded rods, nuts, washers & other customised fastener parts, with coarse and fine threads. 15-5ph stainless steel fasteners are high tensile components, produced from forging stock and bar stock and heat treated to specification, to meet desired mechanical properties. 15-5ph fasteners can be produced in metric and imperial sizes as per DIN, ISO, ASME or any international dimension standards.

15-5ph is a precipitation hardened stainless steel alloy, developed for high tensile applications in field of aerospace, marine & offshore, high speed automotive engineering, nuclear power extraction equipments and paper pulp processing. 15-5ph is a variant to 17-4ph Chromium Nickel Copper Alloy with effective performance in high pressure corrosive environments. UNS S15500, Alloy XM-12, DIN EN 1.4545 are grade equivalents of 15-5ph stainless steel.
