Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized P355GH used for gas industry are higher than that of annealed p355gh used for gas industry, but the elimination of internal stress is not as good as annealing. The normalizing operation of p355gh used for gas industry is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Vanadium mainly exists in the form of carbide in p355gh used for gas industry and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep p355gh used for gas industry processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and p355gh used for gas industry steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Affected by the weak futures performance and weak spot follow-up, the steel billet price is temporarily stable. The overall growth trend of China's p355gh used for gas industry is slowing down, and the demand in the north is lower than that in the south. Under the background of economic recovery, the demand toughness still exists, the resource inventory is tight, and the actual willingness of the spot merchants to let the price is not obvious. The price of p355gh used for gas industry is expected to be adjusted and operated stably.
