A588 Grade A hot rolled strip, 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 A588 Grade A hot rolled strip, 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%.
Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. A588 Grade A hot rolled strip, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of A588 Grade A hot rolled strip, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.
The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. A588 Grade A hot rolled strip, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
A588 Grade A hot rolled strip, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.
The company is mainly engaged in A588 Grade A hot rolled strip steel plates manufacturing and deep processing, sales and distribution.
