Stainless Steel AL 17-4™ Precipitation

Allegheny Ludlum's AL 17-4™ Precipitation Hardening Alloy (S17400), Type 630, is a chromium-nickel-copper precipitation hardening stainless steel used for applica-tions requiring high strength and a moderate level of corrosion resistance. High strength is maintained to ap-proximately 600°F (316°C).

Stainless Steel – Specifications, Grades and Properties

Precipitation hardening grades, like 17-4 PH (also known as 630 stainless steel), are supplied as solution treated bars. They can then be machined before hardening. The hardening process is a single, low temperature, ageing step. Good to moderate corrosion resistance Good weldability Very high strength Magnetic Specifications Grade compositions ...

SUBJECT GUIDE Heat Treating

Precipitation hardening (age hardening) involves heating an alloy to a sufficiently high temperature so that enough of an alloying element is dissolved to form a supersaturated solid solu - tion. It is then rapidly cooled (quenched) to room temperature, Fig. 1 Effects of annealing on brass (Cu-35%Zn).

hardening, age hardening, and precipitation heat treatment are synonymous terms). Alloy 718 is hardened by the precipitation of secondary phases (e.g. gamma prime and gamma double-prime) into the metal matrix. The precipitation of these nickel-(aluminum, titanium, niobium) phases is induced by heat treating in the temperature range of 1100 to ...
