Seamless steel pipe (4130 steel pipe) chrome molybdenum alloy steel pipe for automobile roll cage
4130 domestic grade 30CrMo is an alloy steel containing chromium and molybdenum. Its tensile strength is generally above 750MPa. The ones seen on the market are mainly bars and thick plates. Thin-walled 4130 steel pipes are used to make bicycle frames. IA and China Automobile Federation’s regulations on steel pipe materials for racing roll cages: cold drawn seamless steel pipes.
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 15-70mm; the hot strength of the steel is also good, with sufficient high temperature strength below 500 °C, but at 550 °C Significant decrease in intensity.
