17-4 PH Stainless Steel

Stainless Steels 17-4 PH

17-4 PH stainless steel equipped with corrosion resistance and high strength for highly stressed and stringent environment requiring these combined mechanical properties.

17-4 PH Stainless Steel17-4 PH or UNS S17400 chromium-nickel-copper hardening stainless steel is extensively used for applications that require corrosion resistance and high strength.

17-4 PH stainless steel can develop its excellent hardness and strength with heat treatment. This stainless steel grade can provide toughness in both welds and base metals.

17-4 PH stainless steels exhibit excellent physical and mechanical properties of high strength, corrosion resistance, and hardness. Their high strength is often maintained to 600°F or 316°C. Mechanical properties in 17-4 grade are optimized through heat treatment.

This stainless steel grade should not be used at the very high temperature which is above 572°F (300°C) or even at very low temperatures. It can also have adequate resistance to stringent environments like diluted acids or salts and atmospheric corrosion where corrosion resistance is highly required. 17-4 can withstand corrosive attacks better than other standard hardenable steels.

This grade is known to provide a very outstanding combination of good corrosion resistance, mechanical properties, and high strength at high temperatures. Distortion and scaling of 17-4 bars are also minimized by low-temperature heat treatments.

A lot of standard heat treatments have been developed making 17-4 PH fit a wide variety of industrial applications:

  • Aerospace applications (turbines blades, etc.)
  • Oil and petrochemicals
  • Food industry
  • Chemical processing equipment
  • Nuclear waste casks
  • Pulp and paper industry
  • Mechanical components
  • General metalworking

We can supply 17-4 PH stainless steels with the standard width and length. But we can also cut custom sizes according to your required widths and lengths.
