UNS S17700 (17-7PH, AISI 631) semi-products for stainless elastic elements, engine thrust unit components, and ship shafts
Product Overview
UNS S17700 (17-7PH, AISI 631) semi-products for stainless elastic elements, engine thrust unit components, ship shafts, and related applications. Available in various product forms including 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 spring applications requiring high strength. This special alloy offers 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
  • Operating 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. The exceptionally high strength of Condition CH 900 offers advantages where limited ductility and workability are permissible.
In its heat-treated condition, this alloy provides exceptional mechanical properties at temperatures up to 900°F (482°C). Its corrosion resistance in both Conditions TH 1050 and RH 950 is superior to that of hardenable chromium types. Material produced by vacuum arc or electroslag remelting is available for increased resistance to fatigue in applications subject to cyclic stresses.

Corrosion Resistance
Corrosion resistance of S17700 stainless steel in Conditions TH 1050 and RH 950 is generally superior to standard hardenable chromium types (410, 420, 431) but 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.
Stress Corrosion Cracking in Marine Environments
Precipitation-hardening stainless steels may be subject to stress corrosion cracking when stressed and exposed to corrosive environments. Testing in marine atmospheres shows S17700 has the greatest resistance to stress cracking in Condition CH 900. Condition TH 1050, although somewhat less resistant than CH 900, appears more resistant than Condition RH 950.
Heat Treatment
S17700 stainless steel requires three essential steps in heat treating: Austenite conditioning, cooling to transform austenite to martensite, and precipitation hardening.
Standard Heat Treatments
Procedures for heat treating material in condition A to conditions TH 1050 and RH 950.
Condition A
For in-process annealing (mill annealing), heat to 1950 ± 25°F (1066 ± 14°C) for three minutes per 0.1 in. (2.5 mm) of thickness, and air cool. This treatment restores ductility of cold-worked material for additional drawing or forming. Annealing is required for severely formed parts to be heat treated to Condition TH 1050 if full response to heat treatment is required, but unnecessary for RH 950 heat treatment.
