High quality s500 steel manufacturer in China

Steel plate cutting, there are many cutting ways, therefore, different cutting equipment will be used. If the flame cutting machine is used, then it is necessary to control the primer. As for the specific reason, it is: if the primer is too small, then it will make the heating speed of the steel plate is too slow, affecting the s500 steel cutting quality and effect. And if the primer is too large, it will also affect the cutting quality, such as making the incision unattractive. In addition, an oxide layer is formed on the surface of the steel plate. Therefore, it is required to control the size of the primer, in order to ensure the quality and effect of cutting.

s500 steel, S355J2+N is a kind of EN10025 European standard steel plate. It is a low-alloy structural steel, equivalent to the national standard GB/T1591-2007, GB/T3274-2008 Q345D, its delivery state is normalized, and the impact requirement is -20 degree impact test. The +N at the back means it is normalizing rolling. It is just a method of naming steel grades in the standard.

The types of steel plates are usually divided into three types: s500 steel thick plates (above 6mm), medium-thick plates (3-6mm) and thin plates (below 3mm) according to their thickness. In terms of plate-making process, low-carbon steel plates can be divided into two types: cold-rolled and hot-rolled. Hot rolling alone can produce low-carbon steel plates of about 1.2mm and stainless steel plates of about 2mm. Thinner s500 steel plates can be manufactured by cold rolling, annealing and tempering rolling.

Steel cutting treatment BBN STEEL can cut various machine tool side plates, special-shaped parts, flanges, bearing seats, embedded parts and other supporting materials for various mechanical engineering, pressure vessels and other supporting materials according to customer drawings, and undertake all kinds of steel plate processing services. High-strength low-alloy plate series, normal carbon plate series, die steel series, boiler and pressure vessel steel, s500 steel, pipeline steel, wind power steel, wear-resistant steel and other high-end steel plates.
