The higher quality p295gh material manufacturer

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 P295GH material are higher than that of annealed p295gh material, but the elimination of internal stress is not as good as annealing. The normalizing operation of p295gh material is simple, the cost is low, the productivity is high, and it is widely used in actual production.

In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and p295gh material 47.521 million tons of South Korea.

SA516 70 grade has the highest tensile and yield strength range due to the highest carbon content (up to 0.28%). For high-grade p295gh material steel plates such as SA516 70 grade, especially thick steel plates need to be preheated during arc welding.

Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process. For booking with the company's seal for booking space, if the accessories for booking space (such as the price confirmation document of the shipping company) need to be provided, they can only be booked with all of them. Obtain the shipping space allocation receipt and extract the ship name, voyage number and B / L number information.
