welding process of hardox 400 has a good market prospect

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, welding process of HARDOX 400. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.Try to use welding process of HARDOX 400 high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the welding process of HARDOX 400 temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. welding process of HARDOX 400, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's welding process of HARDOX 400 steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole welding process of HARDOX 400 steel transportation industry.It is a modern high-tech professional enterprise integrating scientific research, welding process of HARDOX 400 production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as welding process of HARDOX 400 process technology development, technology transfer and related technical consulting and technical services.
