Chrome-Moly low alloy steel RSt37-2, SA283 Grade C carbon steel series contains 0.5% - 9% Cr and 0.5% - 1% Mo and lower than 0.20% carbon. 40CrNiMoA, 4340 and SNCM439 are the low alloy chromoly steel materials from the different standards. 40CrNiMoA steel RSt37-2, SA283 Grade C carbon steel is a Chinese standard chromium-molybdenum high strength steel with good hardenability and toughness.
As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.
As the thickness and hardness of RSt37-2, SA283 Grade C carbon steel increase, the tendency to crack at the cutting edge increases. In order to prevent the RSt37-2, SA283 Grade C carbon steel from cutting cracks, preheating should be carried out before RSt37-2, SA283 Grade C carbon steel cutting. Special attention should be paid to preheating to make the entire RSt37-2, SA283 Grade C carbon steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole RSt37-2, SA283 Grade C carbon steel cannot be preheated, the partial preheating method can be used instead.
In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate RSt37-2, SA283 Grade C carbon steel for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 RSt37-2, SA283 Grade C carbon steel and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
