Stainless Steel 17-4 H1075

Specs: ASTM-A564, ASME-SA-564, AMS 5643
UNS#: S17400

Stainless Steel 17-4 H1075 is a precipitation-hardening martensitic Stainless Steel, which has corrosion resistance comparable to austenitic varieties. Our 17-4 H1075 has been heat-treated to a minimum tensile strength of 145ksi, yield strength of 125ksi, an elongation in 2in of 13%, and a reduction of area of 45%. Cobalt is reported in the chemistry.

The H1075 condition offers an effective balance of strength and toughness, making this alloy suitable for demanding applications. Its precipitation-hardening characteristics help maintain mechanical performance in components that require reliable structural integrity. 

Save time and money by buying the material to your heat treatment. We do all work in large batches, driving the cost down and offering you a fast delivery. Free heat treat charts will be included in our cert package upon request.

Engineers often choose 17 – 4h1075 when applications demand consistent mechanical properties and good corrosion resistance. The H1075 designation indicates an aging treatment at 1075°F, which develops the alloy’s characteristic combination of strength and ductility. 

17-4 H1075 is used in applications for aerospace, chemical processing equipment, oil and petroleum refining equipment, food processing equipment as well as general metalworking.

Available shapes – round and rectangular
