17 4 Stainless Steel Hardness Chart

The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.

17 4 stainless steel hardness chart. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. In addition it is more cost effective than many high nickel non ferrous alloys. Appendices printed november 2000 1 s9 chemical analysis specified grade uns no. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice.

Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys. The numbers 17 4 refer to its composition. 17 chromium and 4 nickel. Table 2 typical mechanical properties property.

17 4 provides an outstanding combination of high strength good mechanical properties at temperatures up to 600 f 316 c and short duration low temperature heat treatments that minimize warpage and scaling. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. 17 4 ph is a chromium nickel grade of stainless that may be hardened by a single low temperature precipitation hardening heat treatment. As sintered heat treated to h900 standard and heat treated to h1150 standard.
