S690QL heat treatment production increased year-on-year in August in China

A514 Gr Q plate is a high strength weldable quenched and tempered steel plate according to ASTM standard. S690QL heat treatment, A514 Gr Q plate is mainly used in places requiring high tensile strength and high yield. A514 Gr Q or A514 Gr Q modified are generally used for lifting gear of engineering vehicle and rack of offshore platform. It varies with thickness. Its hardness is 235-290, yield is more than 630MPa, and tensile strength is more than 700MPa.

What is the specific use of S690QL heat treatment, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.

Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China.

In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.

Rizhao Steel 5#ESP Headless Strip Production Line Project is a key construction project in Shandong Province. It is also the fifth domestic ESP production line introduced by Rizhao Steel and the sixth ESP production line in the world. Its thinnest design is 0.5mm, which is at the world's leading level. The more than 20 important nodes set by the entire project have been basically completed, and the equipment has entered the commissioning stage. It is expected to be put into operation at the end of November.
