20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. hot roll carbon steel, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher. The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.
Rotability of low-carbon steel sheet, a variety of hot roll carbon steel 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.
The company cooperates with hot roll carbon steel steel plants such as Maanshan Iron and Steel, Youdan, Liugang, Tangshan Iron and Steel, Xinyu, Jinan Iron and Steel, Shougang, Shagang, Rizhao, Pinggang, Xicheng, Dachang and other steel mills all year round. Alloy plate, hot roll carbon steel boiler plate, container plate, carbon plate, open plate, I-beam, angle steel, channel steel, H-beam, round steel, steel pipe, hot rolled coil, cold rolled galvanized and other spot stocks.
This week, the price of hot roll carbon steel futures rose sharply, and the market mentality was positive. On the one hand, the recent arrival of steel mills is still not much, which has a certain support for the price. On the other hand, the business confidence in the future market is gradually restored, and the willingness to support the price is strong. Today, the move up momentum of hot roll carbon steel futures weakened. In the short term, there may be a slight adjustment pattern, but the probability of a sharp decline is small. It is expected that the hot roll carbon steel market will be mainly volatile tomorrow.
