Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.
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 normalized ABS EH36 naval engineering steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main normalized ABS EH36 naval engineering 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.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the normalized ABS EH36 naval engineering steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After normalized ABS EH36 naval engineering steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
normalized ABS EH36 naval engineering steel, Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our normalized ABS EH36 naval engineering steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's normalized ABS EH36 naval engineering steel customer service to establish a good, comprehensive, full service system.
