Luois Metals stands out as a top-notch manufacturer and supplier of Carbon Steel A350 LF2 bars and rods, proudly operating from our facility in Houston, USA. We’re known for our unwavering commitment to quality and precision, delivering forged carbon steel products that meet the rigorous standards needed for low-temperature applications. Our A350 LF2 bars and rods are perfect for pressure systems and pipelines, boasting impressive toughness and durability. With a variety of sizes and customizable options at your disposal, Luois Metals ensures you receive reliable, high-performance carbon steel solutions with quick turnaround times and outstanding service throughout the United States and beyond.
The Carbon Steel A350 LF2 bars and rods are primarily made up of carbon, manganese, phosphorus, sulfur, and silicon, along with trace elements that boost strength and toughness. Specifically designed for low-temperature service, A350 LF2 offers a tensile strength of about 485 MPa and a yield strength of around 250 MPa. It also showcases remarkable notch toughness and impact resistance even in sub-zero temperatures. The steel undergoes heat treatment (usually normalization) to guarantee consistent mechanical properties and enhanced ductility. While it’s not naturally corrosion-resistant, it can be coated or plated for extra protection in challenging environments.
