Weston Stainless, a Midland, UK-based company, is a leading supplier of high-quality stainless steel products with long-lasting and precision-engineered solutions for a wide range of industries. Stainless Steel 17-7 PH Pipes are produced from a precipitation-hardening chromium-nickel-aluminum alloy with superior strength, corrosion resistance, and high fatigue properties. The pipes come in various shapes, such as round, square, and rectangular, and are suitable for aerospace, marine, chemical, and industrial applications. 17-7 PH grade guarantees better hardness, resistance to wear, and flexibility, so these pipes are highly dependable for harsh environments demanding toughness, durability, and long-term structural integrity.
Stainless Steel 17-7 PH Pipes are made up of 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. These pipes are found to possess a tensile strength of 1034 MPa at best, a yield strength of 724 MPa, and 6-10% elongation, thus rendering outstanding mechanical property. Their physical characteristics consist of a density of 7.8 g/cm³, a melting point of around 1400-1450°C, and thermal conductivity of 16.3 W/m·K. Such properties render them suitable for use in high-stress applications needing superior strength, corrosion resistance, and durability.
