Product Details

17-7PH Bolt
BDF can produce qualified 17-7PH bolt of all kinds of cold formed and hot forged. The forms are hexagon bolts, hex heavy bolts, socket cap bolts, anchor bolts, and other non-standard bolts according to customer drawings. The size ranges from M8-M100 in METRIC and 3/8” to 3-1/2” in INCH, with varies length.
17-7PH is a chromium-nickel-copper precipitation hardening martensitic stainless steel that combines oxidation and corrosion resistance comparable to 304 in most environments with high strength and hardness. It is the most widely used of all the precipitation hardening stainless steels, and is more cost effective than many high nickel non-ferrous alloys in someApplications. 17-4PH cannot be used at temperatures above 300℃ and at cryogenic temperatures. It is magnetic.
