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 hot roll coil steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main hot roll coil 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 superior geographical position and convenient transportation. Our main steel products are: low alloy high-strength plate, carbon structural plate, alloy structural plate, bridge plate, building structural plate, shipbuilding and offshore oil production platform plate, boiler and pressure vessel plate, pipeline plate, weathering steel plate, hot roll coil steel, etc.. In line with the principle of "not striving for the lowest price, but the best quality", the company wholeheartedly provides high-quality steel products and sincere services for users at home and abroad.
Laser cutting hot roll coil steel has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the hot roll coil steel cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as hot roll coil steel.
