Solitaire Steel is recognized as a highly reliable supplier of ASTM A519 Grade 1040 Carbon Steel Seamless Tubes from India. These medium carbon steel tubes contain 0.37-0.44% carbon and 0.60-0.90% manganese, making them strong, ductile, and durable for general-purpose applications worldwide. Manufactured to meet ASTM specifications, these tubes are also known as carbon steel tubings.
The ASTM A519 Grade 1040 specification covers various carbon and alloy steel seamless mechanical tubing. For welding, the technique must suit the grade and intended service. To get the best results, include a print or sketch of the required part, and we will assess the grade, chemical composition, and surface condition to recommend the ideal tube size.
AISI 1040 is a medium carbon steel known for its excellent hardness, strength, and ductility, making it suitable for manufacturing gears, shafts, and axles. Its outstanding heat resistance makes it ideal for applications requiring extreme temperatures, withstanding up to 800°C without losing its mechanical properties.
This combination of durability, heat resistance, and strength makes ASTM A519 Grade 1040 tubes a reliable choice for various engineering and industrial applications.
