P355GH hardness property, 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.

20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than p355gh hardness property, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as p355gh hardness property, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.

In October, the demand for finished products improved significantly, breaking through the high of 4.4 million tons per week, and the price of black products went up overall. Among them, coke performed particularly well under the stimulus of downstream shortages and high molten iron output. It wasn't until early November that coke futures prices fell from a high level due to high disk premiums. After six rounds of increases, the spot price also began to weaken. Downstream steel mills were more resistant to the seventh round of increases.
