sa709gr50 asme bridge steel, Q355NE is a kind of low alloy steel, which is widely used in bridges, vehicles, ships, buildings, pressure vessels and special equipment.Q355NE mechanical performance analysis:The thickness of Q355NE is 6mm-40mm, the tensile strength is 470MPa-630MPa, the yield strength is not less than 335MPa, and the elongation is not less than 21;The thickness of Q355NE is 40mm-100mm, the tensile strength is 470MPa-630MPa, the yield strength is not less than 305MPa, and the elongation is not less than 20;The thickness of Q355NE is 100mm-400mm, the tensile strength is 450MPa-600MPa, the yield strength is not less than 265MPa, and the elongation is not less than 17.
In the past 10 years, domestically-made offshore platform steel has been widely adopted in China's offshore oil projects, and offshore platform steel has gradually developed in the direction of high strength. Relevant data show that the pile legs, pile boots, cantilever beams and other key parts of the jack-up platform require high load. In order to improve the stability of the hull during towing after floating, it needs to be lightweight, and high-strength steel plates must be used.
Our company mainly produce automobile steel plates, ordinary carbon low-alloy steel, container plates, ship plates, container plates, weathering steel, petroleum pipes, pipeline steel, sa709gr50 asme bridge steel cold-rolled silicon steel, etc., which are widely used in various fields of the national economy.The BEBON brand is not only a symbol of strength, but also an embodiment of wisdom.
According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic sa709gr50 asme bridge steel steel exports to 2.44 million tons, down 2.4 percent year on year, after January down 3 percent, the second consecutive month of decline. In the past three years, South Korea's steel exports have decreased year by year, from 31.67 million tons in 2017 to 30.44 million tons in 2018 and 30.38 million tons in 2019. Instead, South Korea's sa709gr50 asme bridge steel steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
