What is the difference between ordinary carbon steel and Q345NQR2 steel equivalent

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural Q345NQR2 steel equivalent steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

At present, the company has successfully developed and produced more than 10 kinds of boron-containing steel varieties such as 35MnBM, 23MnBM, Q345NQR2 steel equivalent, 27MnTiB, 40MnB, 25CrMoTi, etc. According to the practice of Laiwu Steel's 50t electric arc furnace-50t LF-60t VD-R11 Lianzhuo-VD Royal alloying process development and production of boron-containing steel, the technical measures for precise control of the smelting of boron-containing steel are analyzed and discussed.

Alloy steel plate is a kind of high strength steel plate, which has good wear resistance. It is suitable for road laying, factory floor and other fields with high wear resistance requirements. The performance of the Q345NQR2 steel equivalent, alloy steel plate is more prominent. The alloy steel plate has good high temperature resistance and low temperature resistance, which will not cause material deformation in any high temperature and low temperature environment. The strength retention of alloy steel plate is better, and the material stability is better.

Vanadium mainly exists in the form of carbide in Q345NQR2 steel equivalent and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

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. Q345NQR2 steel equivalent, 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.

The consistent tenet of honest management! Know the needs of customers, for the needs of customers, urgent customers think! Our quality is better for the Q345NQR2 steel equivalent same products, our price is lower for the same quality, and our service is better for the same price. welcome to purchase steel materials from our company. we have the professional team and good after-sale system to customers. our company Q345NQR2 steel equivalent is your best choose.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
