S275M steel plates Rolling

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. S275M steel plates, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld S275M steel plates steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for S275M steel plates manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
