The production limit boosts the JIS SS400 plates price by stage

Q370q steel is a kind of bridge steel plate. It is delivered in hot rolled, normalized condition. There are three quality levels Q370qC, Q370qD, and Q370qE. Bridge steel Q370qC, Q370qD, JIS SS400 plates and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃. Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated. When mechanical properties are required, large thickness must be normalized. The thickness of Q370q steel plate we supply is above 8mm.

The company specializes in the research and development, production and sales of JIS SS400 plates seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has JIS SS400 plates five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,JIS SS400 plates rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Laser cutting, it is a specific way of cutting JIS SS400 plates steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting JIS SS400 plates speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

Oxygen (O) is a harmful element in steel such as JIS SS400 plates. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality JIS SS400 plates products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
