Effect of S content fluctuation on mechanical properties of 09cuptire-a steel material

Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. 09CUPTIRE-A steel material steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This 09CUPTIRE-A steel material method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

09CUPTIRE-A steel material, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.

ArcelorMittal said it was taking measures to cut its North American 09CUPTIRE-A steel material steel production in response to the weakening demand for downstream steel after the outbreak of covid-19, foreign media reported. It is reported that ArcelorMittal's plant in the port of Indiana is ready to shut down the No. 4 blast furnace.
