690ql steel, 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.

Manganese steel vs carbon plateManganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and 690ql steel is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common."

Affected by the weakening of the futures steel market, the market sentiment is cautious. Considering the resource cost, the 690ql steel merchants have strong willingness to stand up price and follow the rise. After the price rise, the 690ql steel merchants' shipment is not smooth, the transaction situation is generally weak, the downstream high level acceptance is weak, and the inventory pressure is not obvious. It is expected that the 690ql steel prices will fall down and adjust in the future.
