S355J0W weathering steel plate rolling points

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

Carbon steel pipe is more often used than alloy steel pipes. Compared with alloy steel pipe, It has the advantage of good performance with lower cost. BBN supplies S355J0W weathering steel plate most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe, erw steel pipe and spiral welded steel pipe.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the S355J0W weathering steel plate steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of S355J0W weathering steel plate seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

S355J0W weathering steel plate, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.
