Weston Stainless in Midland, UK, is a major manufacturer and supplier of high-quality stainless steel products that provide superior quality materials for a range of industrial uses. It is specialized in Stainless Steel 17-4 PH Bars that are renowned for their superior strength, corrosion resistance, and hardness. These bars are provided in Grade 17-4 PH, a precipitation-hardening stainless steel that exhibits superior mechanical properties. Produced in round, square, and hexagonal forms, the material is mostly made up of chromium, nickel, and copper, providing maximum durability and wear resistance. The bars are extensively applied in aerospace, marine, chemical, and automotive sectors for high-performance uses.
17-4 PH Stainless Steel Bars contain about 15-17.5% Chromium, 3-5% Nickel, 3-5% Copper, with minor content of Niobium and Manganese, and the rest is Iron. Mechanically, they have a tensile strength of up to 1310 MPa, yield strength about 1180 MPa, and hardness up to 38 HRC, depending on heat treatment. Their physical characteristics are a density of 7.75 g/cm³, a thermal conductivity of 18 W/m·K, and an electrical resistivity of 80 µΩ·cm. All these characteristics suit them for uses in applications needing high strength, toughness, and resistance to corrosion under harsh environments.
