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.
Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, GL-EH 40 higher strength steel angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding GL-EH 40 higher strength steel products, which we source out from the mills that are compliant with the universal guidelines for plate production.
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the GL-EH 40 higher strength steel steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the GL-EH 40 higher strength steel weathering steel is purified and the content of inclusions is greatly reduced.
The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, GL-EH 40 higher strength steel, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.
The company has a professional after-sales service team and good after-sales service reputation, providing full and uninterrupted after-sales service, to ensure timely and rapid solution to customer problems.
