Stainless Steel 17-4 H1025

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

Stainless Steel 17-4 H1025 is a precipitation-hardening martensitic Stainless Steel, which has corrosion resistance comparable to austenitic varieties. Our H1025 has been heat-treated to the minimum tensile strength of 155ksi, yield strength of 145ksi, an elongation in 2in of 12%, and a reduction of area of 45%. Cobalt is reported in the chemistry.

The H1025 designation refers to an aging treatment at approximately 1025°F, which helps the alloy achieve a balance of strength and toughness. This combination makes 17 – 4 h1025 a practical choice for components that must withstand mechanical stress while maintaining reliable performance in demanding industrial environments.

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

17-4 H1025 is used in applications for aerospace, chemical processing equipment, oil and petroleum refining equipment, food processing equipment as well as general metalworking.

Its combination of corrosion resistance and mechanical strength makes it suitable for applications such as pump shafts, valve components, and structural fittings. Engineers should evaluate specific operating conditions when selecting this alloy for their projects.
