Grade S355J2 is an unalloyed welded structural steel with guaranteed impact work at a temperature of -20ºС. It is used in industrial and civil engineering, as well as in the construction of oil and gas platforms, other offshore structures, power transmission towers and other metal structures. Steel S355J2 is actively used to manufacture elements of heavy ground and underground equipment (bulldozers, excavators and dump trucks), railway wagons and agricultural machinery.
The company attaches great importance to systematic management, and has passed the A514 grade P quenched and tempered steel ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A514 grade P quenched and tempered steel quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders A514 grade P quenched and tempered steel WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.
30CrMnSiA steel delivery status: A514 grade P quenched and tempered steel, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, A514 grade P quenched and tempered steel sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
