The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, 100mm GL-A40 quenched and tempered steel professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better 100mm GL-A40 quenched and tempered steel tomorrow!
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.
As the thickness and hardness of 100mm GL-A40 quenched and tempered steel increase, the tendency to crack at the cutting edge increases. In order to prevent the 100mm GL-A40 quenched and tempered steel from cutting cracks, preheating should be carried out before 100mm GL-A40 quenched and tempered steel cutting. Special attention should be paid to preheating to make the entire 100mm GL-A40 quenched and tempered steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole 100mm GL-A40 quenched and tempered steel cannot be preheated, the partial preheating method can be used instead.
In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.
Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. 100mm GL-A40 quenched and tempered steel, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.
Corporate mission: to provide high quality steel products 100mm GL-A40 quenched and tempered steel and services to global customers.Strategic goal: to be the leading steel materials supplier in the world.Enterprise core values: people-oriented, customer first, quality oriented, comprehensive and open, continuous innovation.Customer first is to always put the satisfaction of customer needs first. The key point is "customer centered". We should consider what customers need us to do, what we have done for them, what else we can do for them.
