The Stainless Steel 17-4 PH pipe fittings are primarily made up of iron, chromium (15–17.5%), nickel (3–5%), and copper (3–5%), giving them a martensitic precipitation-hardening structure. This alloy is known for its excellent corrosion resistance in moderately aggressive environments, along with impressive strength and hardness. Mechanically, these fittings can achieve tensile strengths of up to 1,200 MPa, yield strength around 1,100 MPa, and hardness levels reaching 40 HRC, depending on the heat treatment process. They maintain dimensional stability and toughness across a wide temperature range, making them ideal for both structural and pressure applications where reliability and durability are essential.
