Q275 steel Description

Q275 carbon structural steel has high strength, good plasticity and machinability, Q275 implements GB/T700 standard, the yield limit is 275Mpa, the tensile strength (σb/MPa) is 410-560, and it has certain welding Small parts can be quenched and strengthened, and are mostly used to manufacture parts that require high strength, such as shafts, agricultural machinery, wear-resistant parts, rail joint splints, backing plates, wheels, rolls, etc.

The equivalent steel of Q275 carbon high strength structural steel is EN 10025 S275JR. Compared with the Q235 steel grade, the yield limit of Q235 plate is 235MPa; the yield limit of Q275 plate is 275MPa. The carbon content of Q275 sheet is generally higher than that of Q235 sheet, and the tensile strength is also higher. The uses of Q275 carbon steel and Q235 steel are also different. Q235 ordinary carbon steel is mostly used in buildings and engineering structures, such as making steel bars or building plant frames, high-voltage transmission towers, vehicles, boilers, containers, ships, etc.
