Weston Stainless of Midland, UK, is a reputable producer of top–class stainless steel solutions, providing resilient and corrosion-proof solutions for an array of industrial needs. In its high-grade range, Stainless Steel 446 Tubing has earned great renown for its exemplary high-temperature resistance, resistance to oxidation, and longevity. Under Grade 446, it comes in round, square, and rectangular forms in different shapes, catering to a range of industry requirements. Made from ferritic stainless steel, it is highly resistant to scaling, thermal fatigue, and corrosive environments and is suitable for use in high-temperature, corrosive, and extreme heat applications.
446 Stainless Steel Tubing is composed mainly of iron with a significant percentage of chromium (23-27%), making it have outstanding oxidation and corrosion resistance. It has minute levels of molybdenum, nickel, manganese, silicon, and carbon, which help increase its mechanical strength. The tubing has a tensile strength of about 550 MPa, yield strength of about 345 MPa, and elongation of 20%. The physical characteristics are 7.7 g/cm³ density, high thermal conductivity, and strong resistance to thermal cycling, so the tubing is suitable for extreme temperature conditions and structural uses.
