17 4 Stainless Steel Hardness Chart

In addition it is more cost effective than many high nickel non ferrous alloys.

17 4 stainless steel hardness chart.

17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. Mechanical properties can be optimized with heat treatment. Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media.

Table 2 typical mechanical properties property. Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved. Appendices printed november 2000 1 s9 chemical analysis specified grade uns no. As sintered heat treated to h900 standard and heat treated to h1150 standard.

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. Stainless steel grade chart atlas steels specialty steels product reference manual section 9. For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice.

As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress. Excellent mechanical properties at a high strength level may be obtained by such treatment. 17 4 stainless steel 17 4 uns s17400. 17 chromium and 4 nickel.

What s it all mean. In gen eral the corrosion resistance of al 17 4 alloy is supe rior to that of the hardenable 400 series stainless steels. In addition it is more cost effective than many high nickel non ferrous alloys. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys.

17 4 stainless steel also known as sae type 630 is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. 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. It also can include between 3 and 5 copper. The numbers 17 4 refer to its composition.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. The grade combines high strength hardness up to 572 f 300 c and corrosion resistance.
