Midland, UK-based Weston Stainless provides high-quality stainless steel products, catering to industries with precision engineering solutions. Pipes made of stainless steel 17-4 PH are manufactured using a precipitation-hardening chromium-nickel-copper alloy known for corrosion resistance, strength, and toughness. The pipes can be produced in various shapes like round, square, and rectangle, depending upon the requirements. The 17-4 PH grade has superior wear resistance, durability, and excellent mechanical properties for assured reliability in severe environments that need high-performance materials with long-lasting strength and structural integrity.
Stainless Steel 17-4 PH Pipes consist of 15-17.5% Chromium, 3-5% Nickel, 3-5% Copper, 0.07% Carbon, 0.15-0.45% Niobium, 1% Manganese, 1% Silicon, 0.04% Phosphorus, and 0.03% Sulfur. They have a tensile strength of up to 1180 MPa, a yield strength of 1034 MPa, and elongation of 10-15%, providing outstanding mechanical performance. Physically, they possess a density of 7.75 g/cm³, melting point of around 1400°C, and thermal conductivity of 18 W/m·K. All these characteristics make them suitable for high-stress applications involving superior strength, corrosion resistance, and durability.
