BBN NM400 plate equivalent best manufacturer in China

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

In the first ten days of February 2020, the key statistics show that steel enterprises produce a total of 19.3943 million tons of crude steel, 17.9747 million tons of pig iron, 17.5904 million tons of steel and 3.225 million tons of coke. This ten day average daily output of NM400 plate equivalent crude steel is 1939400 tons, down 2.68% on a month on month basis, up 3.16% on a year-on-year basis; steel is 1759000 tons, down 9.09% on a month on month basis, up 2.51% on a year-on-year basis.

NM400 plate equivalent, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the NM400 plate equivalent steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.

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 NM400 plate equivalent 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 NM400 plate equivalent seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
