Weston Stainless, Midland, UK, is a reputable distributor of quality stainless steel products with expertise in precision-engineered components for several industries. One of their products, Stainless Steel 304L Pipe Fittings, are used extensively due to their superior corrosion resistance, strength, and weldability. Made of Grade 304L stainless steel, these fittings contain a low carbon level to avoid carbide precipitation upon welding. They come in a range of shapes, such as elbows, tees, reducers, couplings, and caps, to suit different industrial needs. The chemical composition of 304L stainless steel provides higher strength, making these fittings suitable for chemical, marine, food processing, and petrochemical industries.
Stainless Steel 304L Pipe Fittings consist of carbon (≤0.03%), chromium (18-20%), nickel (8-12%), manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%), providing superior corrosion resistance and weldability. Their mechanical properties are tensile strength of ≥485 MPa, yield strength of ≥170 MPa, elongation of ≥40%, and hardness of ≤201 Brinell (HB). The physical characteristics have a density of 8.0 g/cm³, melting point of 1400-1450°C, thermal conductivity of 16.2 W/m·K, and electrical resistivity of 720 nΩ·m, which are suitable for piping systems in industrial and marine applications.
