Cutting service of Q235D carbon steel plate sheet

Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.

Carbon steel pipe is more often used than alloy steel pipes. Compared with alloy steel pipe, It has the advantage of good performance with lower cost. BBN supplies Q235D carbon steel plate sheet most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe, erw steel pipe and spiral welded steel pipe.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized Q235D carbon steel plate sheet are higher than that of annealed Q235D carbon steel plate sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of Q235D carbon steel plate sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Q235D carbon steel plate sheet, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.
