Rotability of low-carbon steel sheet, a variety of ASTM A36 carbon steel plates low-carbon steel sheets with different metallographic properties and mechanical properties were subjected to deep-drawing spinning tests, from which the following points are directly related to the rotatable properties. The maximum elongation strain of aluminum killed steel plate of general purity exceeds 250% during deep drawing and spinning. The ultimate elongation of the boiling steel sheet with lower purity decreases with the increase of the oxygen content of the steel sheet.
Cleveland cliffs, the largest ASTM A36 carbon steel plates iron ore company in North America, announced on April 13 that its Northshore mine in Minnesota and Tilden mine in Marquette County, Michigan, will suspend production based on the current market environment. The company said it would reduce inventory levels in both regions, while continuing to ASTM A36 carbon steel plates ship iron ore to its customers to meet commercial agreements.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the ASTM A36 carbon steel plates steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its ASTM A36 carbon steel plates steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
ASTM A36 carbon steel plates, Q195 and Q235 belong to carbon structural steel, which are mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Of course, there are many differences between Q195 steel and Q235 steel. 1. Different components. The chemical composition of Q195 steel: C ≤ 0.12, Si ≤ 0.30, Mn ≤ 0.50, P ≤ 0.035, S ≤ 0.040. The chemical composition of Q235 steel: C ≤ 0.22, Si ≤ 0.35, Mn ≤ 1.40, P ≤ 0.045, S ≤ 0.050. 2. The prices of ASTM A36 carbon steel plates, Q235 steel is higher than that of Q195 steel. 3. The mechanical properties of Q195 and Q235 steel are different. The tensile strength of Q195 steel is ≥390 MPa, yield strength is ≥195 MPa, and the elongation is ≥ 30%. The tensile strength of Q235 steel is 490 MPa, yield strength is ≥235 MPa, and the elongation is 23%.
