40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ～ 60mm when water quenching, and Ф15 ～ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ～ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for sa573gr.70 size pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common sa573gr.70 size carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
The executive standard of P235TR1 steel is EN 10216-1. sa573gr.70 size, P235TR1 steel is suitable for manufacturing pipes, vessels, equipment, pipe fittings and steel structures. Chemical composition of P235TR1 steel: C ≤ 0.16, Si ≤ 0.35, Mn ≤ 1.2, P ≤ 0.025, S ≤ 0.02, Cr ≤ 0.30, Mo ≤ 0.06, Ni ≤ 0.30, Cu ≤ 0.30, Nb ≤ 0.01, Ti ≤ 0.04, V ≤ 0.02. Chemical composition of P235TR1 steel: tensile strength 360-500 MPa, yield strength ≥ 235 MPa, elongation ≥ 25%. The main steel pipe grades under EN 10216-1 are P195TR1, P195TR2, P235TR1, P235TR2, P265TR1 and P265TR2.
