The company has allocated special environmental protection facilities for all ASTM A709 structural steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, ASTM A709 structural steel steel mill scale, environmental protection dust has reached 100%.
Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, ASTM A709 structural steel produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, ASTM A709 structural steel steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.
Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the ASTM A709 structural steel special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. ASTM A709 structural steel, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with ASTM A709 structural steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
We have a professional production team and high-quality production equipment, and we also have a great ASTM A709 structural steel advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the ASTM A709 structural steel production of high-quality steel plates, steel pipes and other products that meet customer requirements.
We guarantee to provide all technical data required by users within one hour to provide reasonable quotation; to provide ASTM A709 structural steel reasonable quotation for products consulted by users within one hour; to provide investigation reception: we guarantee to receive the investigation of users at any time and provide various convenient conditions for users.
