34CrMo4 hot-rolled seamless pipe is an alloy steel pipe mainly used to manufacture CNG cylinders, vehicle compressed natural gas cylinders and other high-pressure vessel cylinders.
The implementation standard of 34CrMo4 hot-rolled seamless pipe is GB/T 18248-2021, which is similar to the Japanese standard JIS G 3429, the international standard ISO 11120, and the European standard EN
{{0}}, American standard ASTM A372/A372M-3 and DOT 49 CFR § 178.37. Its chemical composition and mechanical properties are: C: 0.30~0.37, Si: Less than or equal to 0.40, Mn: {{20}}.60~0.9{{30}}, P, S: Less than or equal to 0.020, P+S: Less than or equal to 0.030, Cr: 0.90~1.20, Mo: 0.15~ 0.30, Ni: Less than or equal to 0.30, Cu: Less than or equal to 0.20; tensile strength Greater than or equal to 980Mpa, yield strength Greater than or equal to 835Mpa, elongation after break Greater than or equal to 12%, -50 degree low temperature impact energy Greater than or equal to 27 Joules.
34CrMo4 hot-rolled seamless pipe is a hot-rolled seamless steel pipe made of 34CrMo4 steel. 34CrMo4 is an alloy steel that is commonly used in pipes and containers that work under high temperatures and pressures, such as certain parts in automobile engines, oil and gas pipes, and boilers. This steel has good mechanical properties and high temperature resistance.
