Cold-rolled ASTM A36 carbon steel sheet steel plates are used for parts that require a large degree of plastic deformation of the material when forming parts, and there must be no wrinkles, cracks, etc. on the surface. For different parts, use different grades of steel plates. For example, the Japanese automotive ASTM A36 carbon steel sheet steel sheet standard is divided into three categories. The first category (SPCC) is ordinary cold-rolled steel sheet, which is usually rolled by rimmed steel, the second category (SPCD) is rolled steel sheet, and the third category (SPCE or SPCEN) ) Is a cold rolled steel sheet for deep drawing.
Grades ASTM A36 carbon steel sheet, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.
Among them, Russia's crude steel output was 71.6 million tons, down 0.7% year on year; Ukraine's crude steel output was 20.8 million tons, down 1.2% year on year. ASTM A36 carbon steel sheet, Crude steel production in the Middle East was 45.3 million tons, up 19.2% year on year. The annual output of crude steel in South America is 41.2 million tons, down 8.4% year on year.
Fine cutting of parts, when the ASTM A36 carbon steel sheet thickness of parts is not greater than 8mm, the verticality of the section can not be greater than 6% of the thickness of parts;When the thickness of the part is 8-14mm, the verticality of the section should not be greater than 8% of the ASTM A36 carbon steel sheet thickness of the part.
