Weston Stainless, Midland, UK, is a well-known supplier of superior quality stainless steel products serving various industrial requirements with precision-engineered solutions. Stainless Steel 17-7 PH Coils are fabricated with a precipitation-hardening chromium-nickel-aluminum alloy that provides outstanding strength, corrosion resistance, and fatigue characteristics. The coils come in various shapes such as strips and rolls and find extensive applications in aerospace, chemical, marine, and industrial sectors. The 17-7 PH grade provides great hardness, outstanding wear resistance, and good formability, rendering such coils highly suitable for demanding conditions of high-performance applications demanding toughness, flexibility, and lasting dependability.
Stainless Steel 17-7 PH Coils contain 16-18% Chromium, 6.5-7.75% Nickel, 0.75-1.5% Aluminum, 1% Manganese, 1% Silicon, 0.09% Carbon, 0.04% Phosphorus, and 0.03% Sulfur. They have a tensile strength of up to 1034 MPa, a yield strength of 724 MPa, and an elongation of 6-10%, providing superior mechanical performance. They have a physical density of 7.8 g/cm³, a melting point of around 1400-1450°C, and a thermal conductivity of 16.3 W/m·K. They are therefore well suited to high-stress applications that need excellent corrosion resistance, strength, and durability.
