Introduction of carbon content of NM400
It is very important for an enterprise to have a sound after-sales service system, which not only ensures the normal outflow and inflow of the company's products, but also improves the trust of the company's products in the hearts of customers. Our company has a special after-sales service team and good after-sales service reputation. In case of any problem in the use of our steel products carbon content of NM400 , whether quality problem or not, the after-sales service department will assist in solving the problem as soon as possible, and regularly consult and track the use of the steel products.
Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. carbon content of NM400, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.
Chemical composition of 12Cr1MoV alloy steel plate: Carbon C: 0.08-0.15; Silicon Si: 0.17-0.37; Manganese Mn: 0.40-0.70; Sulfur S: allowable residual content ≤ 0.035; Phosphorus P: allowable residual content ≤ 0.035; Chromium Cr: 0.90-1.20; Nickel Ni: allowable residual content ≤ 0.030; Cu: allowable residual content ≤ 0.030; V: 0.15-0.30; Mo: 0.25-0.30.Delivery status of carbon content of NM400, 12Cr1MoV alloy steel plate: delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment status, and the delivery status shall be indicated in the contract.
The main characteristics of carbon content of NM400, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.
Our company will accept the product quality objection registration record, pass it to the carbon content of NM400 production unit and relevant departments, and timely coordinate the supervision of product carbon content of NM400 quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
