SAE 4130 domestic grade 30CrMo is an alloy seamless steel pipe 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 SAE 4130 cold drawn seamless steel pipes
are used to make bicycle frames. IA and China Automobile Federation’s regulations on steel pipe materials for racing roll cages: precision mechanical seamless steel tubes.
SAE 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. SAE 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.
Shandong Haihui Steel Industry Co., Ltd. has an annual inventory of 20000 tons of seamless steel pipes, including ASTM A106 GR.B/A53GR.B/API 5L GR. B seamless steel pipes, 15CrMo alloy seamless steel pipes, 20Cr alloy seamless steel pipes, 40Cr alloy seamless steel pipes, 27SiMn seamless steel pipes, SAE1010/1020/1035/1045 seamless steel pipes
