hardox 450 vs ar450 PVQ steel plate

What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel Hardox 450 vs ar450.

It is a modern high-tech professional enterprise integrating scientific research, production and sales.

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 Hardox 450 vs ar450 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 Hardox 450 vs ar450 seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Boilers with different parameters, different capacities, and different structures have different Hardox 450 vs ar450, steel consumption rates. Boilers with small capacity and high steam parameters have high steel consumption. Boilers with low steam parameters mainly use low-carbon steel, while boilers with high parameters use a larger amount of heat-resistant alloy steel, and their cost is much higher. In addition, because the once-through boiler has no steam drum or downcomer, steel consumption has also been reduced.

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
