Manganese plays an important role in s355jr carbon steel plates

The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of s355jr carbon steel plates seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.

The weldability of s355jr carbon steel plates is good. It means that under certain process and construction conditions, s355jr carbon steel plates can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.

In addition, the sulfide was fed with silicon calcium wire to control the sulfide into spherical or irregular angular particle shape, which changed into elliptical shape with less harm to stratification after rolling. Reduce the effects of component segregation. Reducing carbon content and manganese content, adopting low phosphorus smelting process, reducing superheat of molten s355jr carbon steel plates steel, selecting reasonable drawing speed and secondary cooling process system, adopting electromagnetic stirring and light pressure continuous casting technology to ensure good working state of casting machine, can effectively reduce center segregation of billet.
