AISI4130 is an American material that follows the ASTM A519/A519M-24 standard
In the aerospace field, 4130 seamless pipes are used to manufacture aircraft structural components, brackets, gears, and piston pins. Due to their high strength and lightweight characteristics, they can effectively reduce weight and withstand dynamic loads. ‌
In the petrochemical industry, it is suitable for high-pressure pipelines, oil pipes, drilling blowout preventers and other equipment, and can withstand high-pressure and corrosive environments. ‌

In the field of automobile manufacturing, it is commonly used to produce engine crankshafts, connecting rods, and transmission shafts to cope with high temperature and high pressure working conditions. ‌

In the field of mechanical manufacturing, it is widely used for quenched and tempered parts such as shafts, bolts, gears, etc., to meet the structural requirements of medium-sized machinery. ‌
In other industrial applications, such as construction machinery, high-pressure conduits, and welded structural components, they are also selected for their wear resistance and corrosion resistance. ‌
4130 seamless pipe is a chromium molybdenum alloy steel that complies with ASTM A519/A519M-24 standards and has the characteristics of high strength, high toughness, and good hardenability. The chromium content in its chemical composition is about 0.8% -1.1%, and the molybdenum content is about 0.15% -0.25%, which endows the material with excellent comprehensive properties, such as tensile strength of 700-900MPa, yield strength of over 500MPa, and maintaining good weldability and processing adaptability. ‌
