17-7PH / 631 / UNS 17700 Stainless Steel Profiles 50mm SS Round Bar
UNS S17700 (17-7PH, AISI 631) semi-products for stainless elastic element, engine thrust unit component, ship shaft applications.
Product Overview
UNS S17700 is available in product forms as plate, sheet, strip, pipe, tube, bar (round, flat, hexagon, square, shapes), wire (profile, round, flat, square), forgings, and more.
Equivalent Designations
07Cr17Ni7Al (GB/T), 17-7PH, AISI 631 (ASTM), SUS 631 (JIS), W.Nr. 1.4568, ATI 17-7™
Applications
UNS S17700 provides valuable property combinations particularly well suited for aerospace and many spring type applications requiring high strength.
This special alloy also provides benefits for applications requiring formability, high strength and good corrosion resistance, including:
Flat springs and belleville (conical spring) washers
Stainless elastic elements and eyelets
Clips, surgical parts, and blades
Bellows, honeycomb, and membranes
Engine thrust unit components and ship shafts
Compressor discs and strain gauges
Suitable for temperatures up to 600°F (316°C).
Material Overview
S17700 stainless steel is a semi-austenitic chromium-nickel-aluminum precipitation-hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment. It is easily formed in the annealed condition, then hardened to high strength levels by simple heat treatments to Conditions RH 950 and TH 1050.

Corrosion Resistance
Corrosion resistance of S17700 stainless steel in Conditions TH 1050 and RH 950 is generally superior to that of the standard hardenable chromium types of stainless steels such as Types 410, 420 and 431, but is not quite as good as chromium-nickel Type 304. Corrosion resistance in Condition CH 900 approaches that of Type 304 stainless steel in most environments.
Heat Treatment
S17700 stainless steel requires three essential steps in heat treating:
Austenite conditioning
Cooling to transform the austenite to martensite
Precipitation hardening
Standard heat treatments present the procedures for heat treating material in condition A to conditions TH 1050 and RH 950.
