17 4 Stainless Steel Hardness Chart

Very high yield strength up to 1100 1300 mpa 160 190 ksi can be achieved.

17 4 stainless steel hardness chart.

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. Table 2 typical mechanical properties property. 17 chromium and 4 nickel.

The numbers 17 4 refer to its composition. Appendices printed november 2000 1 s9 chemical analysis specified grade uns no. Al 17 4 precipitation hardening alloy is comparable to that of type 304 stainless steel in most media. 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.

Alloy 17 4ph is a precipitation hardening martensitic stainless steel with cu and nb cb additions. 17 4 ph is a chromium nickel grade of stainless that may be hardened by a single low temperature precipitation hardening heat treatment.

In addition it is more cost effective than many high nickel non ferrous alloys. As sintered heat treated to h900 standard and heat treated to h1150 standard.

For applications requiring high strength and hardness plus corrosion resistance this alloy is an outstanding choice. What s it all mean. 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. 17 4 ph stainless steel 3 17 4 ph stainless steel provides excellent mechanical properties.

17 4 ph stainless steel mechanical properties ak steel 17 4 ph stainless steel provides excellent mechanical properties. Excellent mechanical properties at a high strength level may be obtained by such treatment. Type 17 4 is the most common grade of martensitic precipitation hardenable ph alloys. As with other precipitation hardening alloys al 17 4 pre cipitation hardening alloy is more susceptible to stress.

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. Mechanical properties can be optimized with heat treatment.
