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. In addition it is more cost effective than many high nickel non ferrous alloys. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.

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. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. Excellent mechanical properties at a high strength level may be obtained by such treatment.

As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress. Table 2 typical mechanical properties property. 17 4 stainless steel 17 4 uns s17400. In addition it is more cost effective than many high nickel non ferrous alloys.

The numbers 17 4 refer to its composition. 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. It also can include between 3 and 5 copper.
