Anucha Metals, a well-known manufacturer and supplier in Bangkok, Thailand, focuses on providing high-quality Stainless Steel 446 Bars and Rods. SS 446 is a ferritic stainless steel that shows excellent resistance to oxidation and scaling at high temperatures. It is built to handle harsh environments, making it durable and reliable for long-term use in extreme industrial settings. At Anucha Metals, each product undergoes strict quality checks, ensuring compliance with international standards. With a commitment to customer satisfaction and performance, Stainless Steel 446 Bars/Rods are trusted in various industries like petrochemical, power generation, furnace construction, and high-temperature engineering.
Stainless Steel 446 Bars/Rods contain chromium (23–27%) with low carbon levels, which gives them outstanding oxidation resistance. This alloy maintains strength at temperatures up to 1100°C while offering creep resistance. Typical mechanical properties include a tensile strength of about 485 MPa, a yield strength near 275 MPa, and elongation up to 20%. They are magnetic and moderately weldable, though welding requires specific techniques. The alloy provides hardness, scaling resistance, and structural stability in high-temperature conditions, making it a reliable choice for critical applications in energy, petrochemical, and furnace industries.
