Table 2 typical mechanical properties property.

Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. In addition it is more cost effective than many high nickel non ferrous alloys. 17 chromium and 4 nickel. As sintered heat treated to h900 standard and heat treated to h1150 standard.

It also can include between 3 and 5 copper. Appendices printed november 2000 1 s9 chemical analysis specified grade uns no. The numbers 17 4 refer to its composition. Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions.

Stainless steel grade chart atlas steels specialty steels product reference manual section 9. Stainless steel grades are lumped into classes the main ones being austenitic ferritic and martensitic the metalworking powers that be developed these classes to consolidate chemical and mechanical properties into categories based on the needs of customers uses. 17 4 ph is a chromium nickel grade of stainless that may be hardened by a single low temperature precipitation hardening heat treatment. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels.

Mechanical properties can be optimized with heat treatment. Excellent mechanical properties at a high strength level may be obtained by such treatment. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice.

17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.
