S420M steel worldwide equivalent grades

In terms of service, our service is a "one-stop" way of working. We have our own S420M steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as S420M steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Flat steel is divided into galvanized flat steel, carbon flat steel, stainless steel flat steel, etc. according to the material. Flat steel can be divided into hot-rolled flat steel and forged flat steel according to the forging process. S420M steel, Hot-rolled flat steel is a potential-rolled long steel with a rectangular cross-section for general use. Forged flat steel is a long steel plate with a rectangular cross section that is forged. Hot-rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery. The thickness of the flat steel is 8-50mm, the width is 150-625mm, and the length is 5-15m.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel S420M steel. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.
