Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A572 grade 65 high strength steel based on a high starting point and high technology, the company has vigorously developed various steel products A572 grade 65 high strength steel and deep-processed parts, steel structures, precision castings, seamless pipes.
The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.
As the thickness and hardness of A572 grade 65 high strength steel increase, the tendency to crack at the cutting edge increases. In order to prevent the A572 grade 65 high strength steel from cutting cracks, preheating should be carried out before A572 grade 65 high strength steel cutting. Special attention should be paid to preheating to make the entire A572 grade 65 high strength steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A572 grade 65 high strength steel cannot be preheated, the partial preheating method can be used instead.
