The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.

14Cr1MoR pressure vessel steel belongs to Cr-Mo anti-hydrogen steel.It is suitable for large-scale equipment such as petrochemical, nuclear power, steam turbine cylinders, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed medium. These 42CrMoS4 round bar for fastener products are also suitable for large equipment such as petrochemical, nuclear power, steam turbine cylinder, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed medium.

The chemical composition difference between 42CrMoS4 round bar for fastener, Q235B and 20# steel is as follows:
The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%.
The difference of mechanical properties between 42CrMoS4 round bar for fastener, Q235B and 20# steel is as follows:
The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the 42CrMoS4 round bar for fastener, alloy steel is very high, it is not easy to break and can be used for a long time.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
