SA514 grade E steel material import and export trade income

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced SA514 grade E steel material technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel SA514 grade E steel material production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

Types of steel plates our company supply: A36 carbon structural steel plate, A572 low-alloy high-strength steel plate, SA514 grade E steel material, steel plate for bridge, S355 steel plate for building structure, Grade AH36 steel plate for shipbuilding and offshore platform, steel plate for boiler and pressure vessel, mould steel plate, steel plate for alloy structure, API 5L Gr.B pipeline steel plate, high-strength high toughness steel plate, corrosion-resistant steel plate, composite steel plate, wear-resistant steel plate.

Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as SA514 grade E steel material, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.

Quenching Improve the hardness of SA514 grade E steel material steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of SA514 grade E steel material steel and comprehensive mechanical properties.
