Fair price S890QL hardness

Our company has S890QL hardness strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply S890QL hardness deep processing service for products S890QL hardness like cutting, drilling, bending, welding and grinding.

Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the S890QL hardness product workpiece, thereby improving the production efficiency and production processing quality.

BBN had provided S890QL hardness Hardox plates for more than 15 years for widely applied in coal mining machinery, cement equipment, road construction machinery, engineering machinery, dump trucks, metallurgical area and port fields. In 2016,we brought our customer to visit our S890QL hardness NM400 steel plate producing line and our Shanghai warehouse for 30000 tons plate and structure. As a result, Our client purchased 500 tons NM 400 as first order, which is shipped by 3 times. In future, BBN will always guarantee that all the delivery condition for Hardox plate provided will be with quenching and tempering, which is the best delivery type according GBT 24186 standard.
