BBN bp440 steel with high quality stock resources

Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. BP440 steel with high quality. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

Ordinary carbon structural steel BP440 steel with high quality has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.

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 BP440 steel with high quality 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 BP440 steel with high quality seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide BP440 steel with high quality cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about BP440 steel with high quality ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
