Weston Stainless, located in Midland, UK, is a renowned supplier of top-quality stainless steel products with specializations in bars, flanges, fittings, and fasteners for industrial uses. Of its products, Stainless Steel 405 Bars are widely known to offer superior corrosion resistance, toughness, and machinability. SS 405 is a ferritic stainless steel with added aluminum for improved oxidation and scaling resistance. These bars come in different shapes, such as round, square, hexagonal, and flat bars, to provide variety in applications. Made from high-quality stainless steel, SS 405 Bars provide strong mechanical strength and durability, which makes them ideal for tough industries.
SS 405 Bars consist of 11.5-14.5% chromium, with minimal content of carbon (0.08% max), manganese, silicon, phosphorus, sulfur, and aluminum, which gives it better oxidation resistance. These bars possess outstanding mechanical properties with a tensile strength of about 450-600 MPa, yield strength of about 205 MPa, and an elongation of 20%. Hardness varies from 170-200 HB to provide wear and durability resistance. SS 405 Bars, in terms of physical properties, have a density of 7.75 g/cm³ and provide good thermal conductivity and reasonable electrical conductivity for their use at high temperatures.

Stainless Steel 405 Bars find broad usage in applications demanding moderate corrosion resistance along with good mechanical strength. They are used extensively in automotive, aerospace, chemical processing, and marine industries on account of their oxidation resistance. They find critical application in the manufacturing of turbine components, heat exchangers, gas equipment for processing, and steam equipment. Their great machinability and toughness make them apt for industrial fabrication, furnace equipment, and welded construction. With greater scaling and stress corrosion cracking resistance, SS 405 Bars are used in high-temperature applications, providing reliability and long-term performance.
