Application of cutting hardox 400 welding
As the thickness and hardness of HARDOX 400 welding increase, the tendency to crack at the cutting edge increases. In order to prevent the HARDOX 400 welding from cutting cracks, preheating should be carried out before HARDOX 400 welding cutting. Special attention should be paid to preheating to make the entire HARDOX 400 welding interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole HARDOX 400 welding cannot be preheated, the partial preheating method can be used instead.
In August 2011, the expanded license for the special equipment material manufacturing of HARDOX 400 welding steel plates for heavy steel boilers and pressure vessels successfully passed the expert review and identification. At this point, the company has the qualification to produce steel plates for boilers and pressure vessels with a maximum thickness of 80 mm. Production continues to be at the leading domestic level. Our boiler steel plate has been widely used in the HARDOX 400 welding manufacture of I, II, III pressure vessels and various pressure vessel reaction tanks.
The technology center has always been focusing on application research, improving market realization and scientific and technological contribution rate; taking user demand as the goal, highlighting the personalized development of products; taking the joint development of industry, University and research, and technology integration as the means, improving the starting point and level of innovation, and realizing the breakthrough of core technology; taking advanced research as the guide, pursuing the leap of technological development; taking system and mechanism innovation as the driving force, Promote and realize the working concept of technological innovation.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel HARDOX 400 welding 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.
we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.
We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about HARDOX 400 welding pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
