EFFECT ON MECHANICAL PROPERTIES DUE TO ALLOYING ELEMENTS
International Journal of Scientific Engineering and Applied Science (IJSEAS)
The present study pertains to changes in mechanical properties of Plain carbon & Alloy steel. An experimental study has been made on Plain carbon and Alloy steel. Two main studies have been carried out. In the first study, Plain carbon steel was prepared in Electric Arc Furnace and subjected to all the heat treatment operation like Annealing, Hardening, Tempering and Stress-relieving. Later on the hardness was also listed for the specimen prepared which was found to be 203 BHN in cast 1 & 207
... N in cast 1 & 207 BHN in T.P. The mechanical properties were also listed and found yield strength 41.99 TSI, 53.85 UTS, 24% Elongation and Impact 70, 71, 72 Ft .Lb. And 5 different readings have been taken on different cast from 1 to 5 to know the exact value. In the second study, alloying elements were added to 5 castings and Heat Treatment process operation were carried out like Normalizing, Hardening, Tempering, and stress-relieving operation for Test piece sample. After that checked the hardness of Cast was found their Cast no 1A 314 BHN and T.P. 320 BHN. Mechanical properties were also checked and the cast no 1A-87.92 Y.S., 112.4 kgf/mm sq UTS, 22%E, and Impact property 8.56, 8.77, 8.77 mm Kgf in alloy steel. And same procedure was carried out for five heat cast heat samples.
