The hot rolling technolodge of nm400 steel specifications

Low alloy steel Q345E angle steel bar can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connecting piece between the components. NM400 steel specifications, Q345E angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, NM400 steel specifications quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the NM400 steel specifications International leading steel materials supplier.

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 NM400 steel specifications 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 NM400 steel specifications weathering steel is purified and the content of inclusions is greatly reduced.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of NM400 steel specifications nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of NM400 steel specifications steel, can be used as an alloying element of low alloy steel.
