Aiman Metals stands out as a top-notch manufacturer and supplier of premium stainless steel products, proudly based in Kuala Lumpur, Malaysia. They specialize in Stainless Steel 321 Flat Bars, providing dependable solutions for industries that demand outstanding corrosion resistance and high-temperature strength. SS 321 is a titanium-stabilized austenitic stainless steel, perfect for applications that involve prolonged exposure to heat. With a strong commitment to quality, precision, and customer satisfaction, Aiman Metals ensures their products meet international standards. Their Stainless Steel 321 Flat Bars find applications across various sectors, including chemical processing, thermal equipment, aerospace, and food production, both in Malaysia and beyond.
Stainless Steel 321 Flat Bar is primarily made up of 17–19% Chromium, 9–12% Nickel, and is stabilized with Titanium (at least five times the carbon content) to prevent carbide precipitation. It has a maximum carbon content of 0.08%. This alloy is known for its excellent resistance to oxidation and intergranular corrosion at high temperatures. Its mechanical properties include a tensile strength of around 515 MPa, yield strength of 205 MPa, and 40% elongation in 50 mm. SS 321 retains good mechanical strength and structural stability in environments reaching up to 870°C (1600°F), making it ideal for heat-intensive applications.

Stainless Steel 321 Flat Bars are extensively utilized in high-temperature industrial settings due to their remarkable resistance to oxidation and intergranular corrosion. You’ll find them in exhaust systems, furnace components, thermal oxidizers, heat exchangers, and parts for aircraft engines. SS 321 is also a go-to choice in chemical processing plants, refinery equipment, and food processing machinery, where high heat and chemical exposure are the norm. Its titanium-stabilized structure not only enhances weldability but also makes it suitable for a wide range of demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
