New breakthrough of S690QL mechanical properties

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 S690QL mechanical properties steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main S690QL mechanical properties 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.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick S690QL mechanical properties steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

Our company was founded in 2009, and has been committed to steel business since its establishment. Over the years, the company's performance shows a good development trend, with a wide range of customers in the government, domestic and foreign markets. The company has always been in line with the tenet of "based on trust and win with quality", focusing on the market demand, with a long-term vision, with years of hard work and trustworthy operation, and the support of the majority of S690QL mechanical properties businesses and customers, has won the unanimous praise and trust of the industry and customers!

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between S690QL mechanical properties, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
