17-4 PH Duplex Stainless Steel Pipe


17-4PH alloy features excellent corrosion resistance, superior to any other hardenable stainless steel. In most cases, it has as good corrosion resistance as type 304. Despite this, stress corrosion can happen under a high-strength state; if there is a risk of stress corrosion cracking, it will be necessary to adjust the stabilization temperature. The alloy 17-4PH is susceptible to corrosion or crack corrosion in static seawater.

Product Details
17-4 ph Stainless Steel is a precipitation hardening martensitic stainless steel. Typical 17-4 ph usage is seen in applications requiring high strength and a modest level of corrosion resistance. Strength and toughness desired can be manipulated by temperate range in the heat treatment process. Below you will find typical applications of 17-4 ph stainless steel as well as the metals composition and mechanical properties.
