ASTM A519 4130 Alloy Steel Pipes

4130 is a common composite steel pipe with a very wide range of applications. It is mainly composed of iron, carbon and the addition of other alloying elements such as chromium, molybdenum and silicon to improve its mechanical properties and corrosion resistance.

introduction
4130 alloy steel pipe contains carbon 0.26~0.34, silicon 0.17~0.37, manganese 0.40~0.70, molybdenum 0.15~0.25, chromium 0.80~1.10. 4130 is equivalent to Japanese SCM430. This steel has high strength and toughness, high hardenability, and the critical hardenable diameter in oil is 15 to 70 mm. The steel also has good thermal strength and has sufficient high-temperature strength below 500°C, but it has sufficient high-temperature strength below 550°C. The intensity dropped significantly.

A519 4130 pipe has good weldability during welding, which makes it easier to process and connect during the manufacturing process. ASTM A519 Gr 4130 Seamless Pipes can be processed in a variety of ways, including bending, forming, forging, etc., to suit different design needs. ASTM A519 AISI 4130 Alloy Steel Pipe, although high in strength, has a relatively low density due to its low-alloy nature, thus reducing the weight of the component while maintaining strength. Due to its comprehensive properties, 4130 steel pipe is suitable for use in a variety of fields, including aviation, aerospace, automobile manufacturing, oil and gas extraction, etc., to meet the needs for high strength and durability in these fields.
