Stainless Steel AISI 17-4ph Fasteners

AISI 17-4ph Equivalent Grades

AISI 4130 Bolts

17-4ph Fasteners are manufactured in varieties of bolts, stud bolts, screws, threaded rods, nuts, washers & other customised fastener parts, with coarse and fine threads. 17-4ph stainless steel fasteners are high tensile components, produced from forging stock and bar stock and heat treated to specification, to meet desired mechanical properties. 17-4ph fasteners can be produced in metric and imperial sizes as per DIN, ISO, ASME or any international dimension standards.

17-4ph is a chromium-nickel-copper alloyed martensitic grade precipitation hardening stainless steel with excellant combination of high strength, corrosion resistance and mechanical properties a temperatures upto 600 deg fahrenheit or 316 deg celcius. 17-4ph stainless steel is a high tensile alloy with prominent usage as fasteners for aerospace industries.
