BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of sa573 gr.58 structural quality carbon steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main sa573 gr.58 structural quality carbon steel production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
The company has an annual spot inventory of 20,000 tons, and its own 20,000 square meter indoor warehouse, with normalizing container plates, API5L Gr.B wide and thick steel for oil and gas pipeline, extra wide and extra thick low alloy plates, sa573 gr.58 structural quality carbon steel, chromium molybdenum steel, high strength plates, bridge plates, weathering steel, and excellent carbon Steel, military steel, etc. It can cut squares, discs, door frames, flanges, special-shaped parts, drilling, beveling, etc.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This sa573 gr.58 structural quality carbon steel alloy steel sa573 gr.58 structural quality carbon steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
Temperature has a great influence on the strength of the material, sa573 gr.58 structural quality carbon steel. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The sa573 gr.58 structural quality carbon steel, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
