Low carbon elongation of nm500 material price per kg

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the elongation of NM500 material project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of elongation of NM500 material customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

Q370qC, Q370qD, elongation of NM500 material and Q370qE are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. Used for the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges).

The difference of chemical composition between elongation of NM500 material, Q420D steel and Q460D steel: Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015. The difference of mechanical properties between elongation of NM500 material, Q420D steel and Q460D steel: The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. elongation of NM500 material, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel elongation of NM500 material plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export elongation of NM500 material to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
