The leading NM450 steel grade supplier and exporter in China

Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between NM450 steel grade, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of NM450 steel grade, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.

NM450 steel grade, 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.

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for NM450 steel grade?
