Aiman Metals stands out as a top-notch manufacturer and supplier of high-quality stainless steel products, proudly rooted in Kuala Lumpur, Malaysia. Among their impressive lineup, the Stainless Steel 321 Hex Bars and Rods are well-known for their remarkable resistance to high temperatures and intergranular corrosion. SS 321 is a titanium-stabilized austenitic stainless steel, perfect for situations where there’s continuous or repeated heat exposure. Aiman Metals guarantees that all their products are crafted to meet international standards, ensuring precision, strength, and durability. They cater to industries like aerospace, chemical processing, and power generation, providing dependable and tailored stainless steel solutions throughout Malaysia and beyond.
Stainless Steel 321 Hex Bar/Rod is made up of 17–19% Chromium, 9–12% Nickel, and is stabilized with Titanium, typically in amounts at least five times the carbon content, which has a maximum of 0.08%. This stabilization helps prevent carbide precipitation during welding and high-temperature exposure. SS 321 boasts excellent resistance to oxidation and scaling up to 870°C (1600°F). Its mechanical properties include a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of 40%, making it a great choice for high-stress, high-temperature applications in tough environments.
