Chuck Metals, located in Pulau Ujong, Singapore, is a reliable manufacturer and supplier of top-notch stainless steel products, including Stainless Steel 321 Bars and Rods. Known for their impressive heat resistance and durability against corrosion, Chuck Metals offers high-quality 321 bars and rods that are perfect for demanding industrial applications. The company prides itself on quality assurance, prompt delivery, and outstanding customer service, catering to industries like aerospace, petrochemical, and power generation throughout Singapore and Southeast Asia. Their products are designed to meet strict standards, ensuring they perform reliably even in tough environments.
Stainless Steel 321 Bars and Rods are made from a titanium-stabilized austenitic stainless steel alloy, featuring chromium content of 17–19%, nickel 9–12%, and carbon up to 0.08%. The addition of titanium helps prevent carbide precipitation, boosting resistance to intergranular corrosion during welding and exposure to high temperatures. In terms of mechanical properties, these bars and rods have a tensile strength of about 75 ksi (515 MPa), yield strength close to 30 ksi (205 MPa), and an elongation of 40%. This alloy also shows excellent oxidation resistance and maintains its strength and structural integrity during extended use at elevated temperatures, typically up to 900°C.
