Product Description

Product Description

 

      4130 steel pipe is a chromium molybdenum alloy steel pipe.
      4130 steel pipe has high strength and toughness, and high hardenability
The tensile strength of 4130 steel pipes is generally above 750MPa, with good hardenability, heat resistance, and corrosion resistance. Through precise heat treatment processes such as quenching and tempering, excellent mechanical properties can be obtained, including high strength, good toughness, and fatigue resistance
     4130 steel pipes are widely used in fields such as automobiles, aerospace, petrochemicals, etc. due to their excellent physical and mechanical properties. In automobile manufacturing, 4130 steel pipes are commonly used to make safety components such as anti roll frames. In addition, 4130 steel pipes are also used to make bicycle frames and other structural components that require high strength and good toughness
