A709MGr36 material is an American standard carbon steel plate for bridges. The bridge plate is a thick steel plate for the manufacture of bridge structural parts. It has been widely used in construction steel structures, construction machinery and other steel structures. Production material A573 Grade 65(A573 Gr 65) specifications: thickness 5mm-400mm, width 1500mm-3900mm, length 3000mm-18000mm. After agreement between the two parties, the supply of steel plates of larger specifications.
Phosphorus is a very harmful element in material A573 Grade 65(A573 Gr 65) steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of material A573 Grade 65(A573 Gr 65) steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
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 material A573 Grade 65(A573 Gr 65) 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 material A573 Grade 65(A573 Gr 65) weathering steel is purified and the content of inclusions is greatly reduced.
Our quality and service commitment: material A573 Grade 65(A573 Gr 65) product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
