Chuck Metals is a trusted manufacturer and supplier of Carbon Steel A350 LF2 Bars and Rods based in Singapore, Pulau Ujong. They cater to various industries, including oil & gas, power generation, and petrochemical processing. A350 LF2 is a low-temperature carbon steel grade celebrated for its toughness, strength, and excellent weldability, even in sub-zero conditions. Chuck Metals provides these bars in a range of sizes and heat-treated options, all while adhering to ASTM A350 specifications. With a strong commitment to quality assurance, quick delivery, and outstanding customer support, Chuck Metals has become a go-to source for essential forged components and structural materials.
The composition of Carbon Steel A350 LF2 Bars and Rods mainly includes carbon (≤0.30%), manganese (0.60–1.35%), along with small amounts of silicon, phosphorus, and sulfur. These materials typically boast a tensile strength ranging from 485 to 655 MPa and a minimum yield strength of 250 MPa. They undergo normalization to enhance impact toughness and ductility at lower temperatures. A350 LF2 is known for its excellent machinability and weldability, making it perfect for applications that demand durability and performance in both regular and sub-zero environments, such as cryogenic services or pressure systems.

You’ll find Carbon Steel A350 LF2 Bars and Rods commonly used in the production of flanges, fittings, valves, pressure vessels, and other components designed for low-temperature service. They play a crucial role in pipeline systems, offshore platforms, LNG plants, and power plants, where dependable performance in cold climates is vital. The alloy’s ability to withstand brittle fracture under impact loads at temperatures as low as –50°C makes it an ideal choice for structural and pressure applications that require consistent strength and ductility.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
