The controlled cooling process of hardox 450 welding

Our quality control department will do inspection for details of the steel materials Hardox 450 welding before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.VL E460 steel: is a structural steel plate for ships and offshore engineering."VL" stands for the abbreviation of "DNVGL", which is a standard certified by the two classification societies of DNV (Norway) and GL (Germany). The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.During the construction of hot-dip Hardox 450 welding galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the Hardox 450 welding construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. Hardox 450 welding, 20CrMo steel pipe is generally used in quenching and tempering state.If you have any requirements for the mode of transportation of the Hardox 450 welding goods, we can also negotiate and meet your requirements. For logistics, first of all, we respect customers' opinions, and then choose the most convenient port and transportation mode with appropriate price for customers.The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products Hardox 450 welding more unique in the same industry, and is favored and praised by users.
