What is the price of impact resistance of NM400 steel plate, spring steel? First, how much a ton of spring steel costs depends on the grade of spring steel, because different grades have different properties and prices. Second, it is also related to the market. The demand for impact resistance of NM400 steel plate spring steel is different every day, and the price of impact resistance of NM400 steel plate, spring steel is also changing every day. We can learn the current price of impact resistance of NM400 steel plate, spring steel through the network and steel market information. Third, how much a ton of spring steel costs depends on the manufacturers. Different manufacturers have different manufacturing quality and prices. Generally, the price of large factories is higher, but the quality is better guaranteed.

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 steel such as impact resistance of NM400 steel plate delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for impact resistance of NM400 steel plate, 42CrMo steel is quenching and tempering.
