Manufacture the 05CuPCrNi grade steel with surface heat treatment

Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.

30CrMnSiA steel is a grade of alloy structural steel. The steel has high strength and poor welding performance. It is a high-strength quenched and tempered structural steel with high strength and sufficient toughness after quenching and tempering, and good hardenability. It has good workability, small processing deformation and good fatigue resistance. 30CrMnSiA steel is mostly used to manufacture various important parts with high load and high speed.

Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. 05CUPCRNI grade steel, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The 05CUPCRNI grade steel metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other 05CUPCRNI grade steel alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary 05CUPCRNI grade steel carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.
