The welding of ASTM A519 Gr.4130 steel tubing

High strength steel ASTM A519 Gr.4130 is a medium carbon modulated Cr-Mo steel with excellent yield strength, tensile strength and notch toughness. The material offers a high carbon content, and the appropriate addition of Cr, Mo and other elements can improve its hardenability and anti-tampering softening tendency, which has been widely used in Marine high-pressure…

A design of 4130 Chromoly steel tube bending

Chromoly steel 4130 has excellent strength and toughness, good hardenability and weldability, is a commonly used steel pipe for structural and mechanical purposes. It is mainly used for quenching and tempering parts with large cross-sections and working under high-stress conditions in the machinery manufacturing industry such as shafts, spindles, high load steering wheels, bolts, studs,…
