nm500 plate thickness size standard sizes

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the NM500 plate thickness size project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.Q690C steel plates are mainly used in heavy machinery, marine engineering, metal structures. BBN STEEL cooperated with Wugang to produce Q690C steel for use in its enterprise production and construction projects. The prospects for produts exporting to the United States, Canada, Australia, India, and Europe are promising. More than 10,000 tons NM500 plate thickness size products have been directly supplied to European customers.40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. NM500 plate thickness size, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.The company's products NM500 plate thickness size have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow. The needs and interests of users are our high philosophy of service and commitment, and customer satisfaction is our eternal pursuit.
