What is the best quality weathering steel Q295NH?

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and weathering steel Q295NH resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, weathering steel Q295NH new materials, and promotes the competition of enterprises Struggle.

weathering steel Q295NH, High-strength steel plates are widely used in many industries such as construction, automobiles, ships, machinery and equipment, but high-strength steel plates must be selected appropriately. First, the grade is too high, which means that the price will be high because of the high manufacturing cost. Second, the low level means that the safety performance cannot meet the standard. Third, we must strictly follow the design drawings to select high-strength steel plates specifications. Fourth, it is advised the purchaser to test the high-strength steel plates with special equipment.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

The work performance of weathering steel Q295NH etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.

The difference between weathering steel Q295NH, 10# seamless steel pipe and 20# seamless steel pipe:
1. Chemical composition
Chemical composition of 10# seamless steel pipe: C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. Chemical composition of 20# seamless steel pipe: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25
2. Mechanical properties
10# seamless steel pipe: tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%. 20# seamless steel pipe: tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%.
