Effect of microstructure on low carbon steel due to variable temperature using plasma cutting / Ahmad Shakell Naim Md Sanusi

A type of metal is low carbon steel, which has an alloying ingredient with only a little amount of carbon. The average carbon percentage of black steel pipe is between 0.04 percent and 0.40 percent, and the average manganese concentration is between 0.30 and 1.4 percent. It has evolved into one of the most popular types of steel used for building because of its reduced cost when compared to other types of steel. In addition, this product can be used effectively to make a wide range of products, such as flat-rolled sheets or steel strips. Low carbon steel needs to be refined extensively before it can be utilised as a heating product. How much heat can low carbon steel withstand because of how much heat it can withstand and what will happen to it if it is exposed to high or low temperatures. When steel is taken out of the press, it retains its strength and does not become brittle, although low carbon steel has a limited ability to measure energy before fracture.The main Objective is to compare microstructure of low carbon steel before and after cutting by using plasma cutting with different temperature. Next , to define mechanical properties of low carbon steel which its toughness, hardness analysis by using rockwell hardness test machine. Sample preparation is the first step in the techniques. Copper was utilised as the material because it is readily available and can be used in laboratory milling. Using a lab microscope, the copper specimen's microstructure is examined, and its hardness is assessed using a Vicker hardness testing device. There will be 6 copper specimen copper plates tested. Safety should come first to prevent harm, so put on your glasses to block out flash and your apron to keep your clothes from catching fire before you start cutting. On six copper specimen plates, the cutting procedure will be carried out using a plasma cutter with various temperature settings. The specimen plate will then be cooled to lower the temperature after being cut. The cut edge surface microstructure of each specimen will then be examined using a microscope in a laboratory setting.
