Hot rolled nm500 grade material vs stainless steel

SA387Gr5Cl2 steel material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of NM500 grade material, SA387Gr5Cl2 steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of SA387Gr5Cl2 steel plate is normalizing plus tempering or normalizing plus rapid cooling plus tempering. By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature.

The Performance requirements of low alloy structural steel, NM500 grade material:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

In actual processing applications, the processing NM500 grade material thickness of flame cutting ranges from 6 to 200 mm, and the NM500 grade material cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting NM500 grade material with a certain thickness above 10mm.
