Chuck Metals stands out as a trusted manufacturer and supplier of top-notch Stainless Steel 446 Bars and Rods right here in Singapore, Pulau Ujong. With a solid reputation for providing heat-resistant and corrosion-resistant stainless steel products, Chuck Metals caters to various industries, including power generation, petrochemical, heat treatment, and furnace manufacturing. Stainless Steel 446 is a high-chromium ferritic alloy celebrated for its exceptional resistance to oxidation, sulfidation, and thermal fatigue, even at high temperatures. Chuck Metals guarantees that all 446 bars and rods are produced in line with international standards, ensuring customers receive consistent quality, durability, and reliable performance in the toughest conditions.
Stainless Steel 446 (UNS S44600) is a high-chromium ferritic stainless steel that boasts 23–27% Chromium, very low Carbon (maximum 0.20%), and small amounts of Manganese, Silicon, Phosphorus, and Sulfur. It shows remarkable resistance to oxidation and scaling up to 1100°C. Its mechanical properties include a tensile strength ranging from 485–620 MPa, a yield strength of about 275 MPa, and a hardness of up to 200 HB. While it may not be ideal for welding or forming like austenitic grades, 446 excels in high-temperature settings, particularly in furnaces and heat exchangers where oxidation resistance is vital.
