PH15-7Mo UNS S15700 X8CrNiMoAl15-7-2 Semi-Austenitic PH Steel Forgings for Aerospace Fasteners, Springs & Bellows Bars & Forgings

Product Description

Jiangsu Liangyi is an ISO 9001:2015-certified forging manufacturer in China supplying PH15-7Mo / UNS S15700 open-die forgings, bars and machined parts to aerospace, spring and high-strength component projects in India and worldwide, to ASTM A564 / A693 and AMS 5520 / 5573.

Why PH15-7Mo / UNS S15700 for Indian aerospace and spring projects

PH15-7Mo is a semi-austenitic PH stainless supplied soft for fabrication, then condition-treated and aged to high strength, with molybdenum giving materially better corrosion and pitting resistance than 17-7PH. For India's aerospace, spring-manufacturing and high-strength component sectors, S15700 suits structural fasteners, springs, diaphragms and bellows.

Documented capability

Aerospace/aircraft structural: structural fasteners, fittings, high-strength bolts, clips.

Springs/flexible components: springs, diaphragms, bellows.

Precision/general: precision bar, strip, machined parts.

General high-strength: discs, hubs, sleeves, custom forgings.

Product range for Indian buyers

Forged and machined springs, diaphragms, bellows; aircraft/aerospace structural fasteners and fittings; high-strength bolts and clips; precision bar, strip and wire-derived parts; discs, hubs, sleeves.
