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, based on a high starting point and high technology, the company has vigorously developed various steel products and deep-processed parts, steel structures, precision castings, seamless pipes.
According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for , 42CrMo steel is quenching and tempering,LR grade E multihull steel.
High wear resistance: fully automatic CNC stacking equipment, independent of manual LR grade E multihull steel welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the LR grade E multihull steel hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite LR grade E multihull steel wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.
After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
The shipping department of the company arranges shipping booking for customers' goods in advance, and makes good matching with inland transportation. Effectively manage and follow up the customer's shipping schedule and give feedback to customers in time. At the same time, the shipping department has a keen insight into the shipping market in different periods to reduce the transportation cost for the company and customers.
We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update LR grade E multihull steel stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs. Welcome to contact us and book steel materials stocks.
