Weston Stainless, based in Midland, UK, is a reliable distributor of top-quality stainless steel products, providing long-lasting and corrosion-resistant solutions for numerous industries. Their Stainless Steel Forged Fittings are made from top-grade stainless steel, providing outstanding mechanical strength, high-pressure resistance, and better corrosion protection. Found in grades like 304, 304L, 316, 316L, 321, and 347, the fittings are in a range of shapes including elbows, tees, couplings, unions, and reducers. As high-performance products, SS forged fittings offer great strength, durability, and weldability, thus suitable to be used in harsh industrial conditions.
Stainless Steel Forged Fittings consist of components like chromium (16-20%), nickel (8-14%), molybdenum (2-3% in some grades), and carbon (up to 0.08%). The fittings have a tensile strength of approximately 515 MPa, yield strength of 205 MPa, and elongation of 35-40%, based on the grade. The hardness is around 90-100 HRB. Physical properties are a density of 7.9 g/cm³, a melting point of approximately 1400°C, and very good thermal conductivity, providing outstanding performance under high-temperature and high-pressure conditions.

Stainless Steel Forged Fittings find extensive application in petrochemical, oil & gas, power plants, chemical processing, and marine sectors. They are suitable for high-pressure pipelines, steam lines, and hydraulic systems where corrosion and strength are essential requirements. These fittings are also used in food processing, pharmaceutical, and water treatment applications because of their superior hygiene and resistance to oxidation. Their outstanding mechanical properties, superior formability, and high resistance to adverse conditions make them the most popular choice for industrial piping systems.
Highly resistant to intergranular corrosion, these fittings are designed for high-pressure applications. They provide a secure, leak-proof connection in sizes from 1/4″ to 4″ and various pressure ratings.
Exceptional resistance to oxidation and high-temperature environments, these fittings are available in sizes from 1/8″ to 4″ NPT. They are ideal for applications where high strength and durability are required.
Corrosion and high temperatures, this elbow allows for smooth changes in pipe direction at a 45-degree angle. Sizes range from 1/2″ to 4″, accommodating various pipe dimensions.
Excellent resistance to corrosion and high temperatures, this tee connects three sections of pipe, allowing for changes in direction. Available in sizes from 1/4″ to 4″ NPT.
Strong corrosion resistance and suitability for high-temperature use, this coupling connects a pipe to a threaded fitting. Common sizes include 1/4″ to 2″ NPT.
Its durability and resistance to corrosive environments, this cross-fitting enables four-way connections between pipes. Available in sizes from 1/2″ to 2″, it ensures robust and reliable performance.
