Harsh Metalloys, located in Mumbai, India, is a reputable manufacturer and supplier of Stainless Steel 446 Bars, celebrated for their remarkable resistance to high-temperature oxidation and corrosion. Crafted from ferritic stainless steel Grade 446, these bars are engineered to endure extreme heat and harsh environments. They come in a variety of shapes, including round, square, and hexagonal, and meet international standards like ASTM A276 and ASME SA276. Commonly utilized in power plants, furnace manufacturing, heat treatment industries, and the petrochemical sector, these bars deliver reliable solutions where high thermal stability and corrosion resistance are crucial.
Stainless Steel 446 Bars are composed of 23–27% Chromium, low Carbon, and minimal Nickel, which gives them exceptional oxidation and sulfidation resistance at elevated temperatures. They boast a tensile strength of around 485 MPa and a yield strength close to 275 MPa. Being ferritic, these bars provide good dimensional stability and resistance to thermal fatigue, though they are not as ductile as austenitic grades. Their high chromium content ensures they are well-protected against scaling and corrosion in sulfur-rich and high-temperature environments, making them perfect for structural and industrial applications in demanding conditions.
