What is the scope of appearance inspection of Q460NH steel for railway rolling stock

Some Q460NH steel for railway rolling stock, low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

According to the difference of Q460NH steel for railway rolling stock automatic steel plate cutting and semi-automatic cutting, the distance of each cutting gun is adjusted, the trailing amount is determined, and the slit compensation is considered.In the cutting process, the size and direction of the Angle of the cutting gun are mainly determined by the thickness of the steel plate.

Q460NH steel for railway rolling stock, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
