What are the influencing factors of flame cutting quality for ASTM A572 carbon steel plate sheet

The Performance requirements of low alloy structural steel, ASTM A572 carbon steel plate sheet:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude ASTM A572 carbon steel plate sheet steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a ASTM A572 carbon steel plate sheet crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.

BBN STEEL is an agreement direct selling agent of Wuyang Iron and Steel Company, which mainly deals in medium and extra wide and extra thick steel plates. There are more than 8,000 tons of steel ASTM A572 carbon steel plate sheet plates of various specifications for customers to choose. The company's steel plate processing plant can cut semi-finished products and special-shaped parts according to user requirements, and can also transport on behalf of office roads, railways and shipping.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products ASTM A572 carbon steel plate sheet are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.
