In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel S550QL steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
ASTM 36 is the most common alloy steel. It is used for most building components, including columns, beams, decorations, and completion elements. ASTM A36 S550QL steel ductility does not allow the alloy to be used as a cable or as reinforcement (reinforcement). However, ASTM A36 is also perfect for most other purposes.
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, S550QL steel 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 S550QL steel International leading steel materials supplier.
Oxygen is a harmful element in S550QL steel steel. With the increase of oxygen content, the strength of S550QL steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S550QL steel steel.
