This study was inspired by the short life of the pins used in cotton seed separating machines in textile industries. The tip has been flame hardened to increase its hardness, and multiple heat treatment processes have been performed to distribute the hard carbide particles uniformly in the slightly soft ferrite matrix. The high carbon steel chosen as a base metal contains enough carbide-forming elements to supply the matrix with fine carbides. When the as-received sample was examined, needle-like martensitic structures with previous austenite grain boundaries were apparent. A carbide deposit forms both at the main and sub-boundary grain boundaries during grain boundary formation. A few spots of retained austenite are visible as white spots at some locations. The percentage of retained austenite is around 1%. With increased tempering time, the carbide was observed to shrink in size until it achieved its smallest size. Within the ferrite/martensitic phase, carbide grew in a specific direction after eight hours of tempering. The XRD results confirmed that these are Fe3C (cementite). SEM study at high magnification reveals the size and distribution of carbides. The existence of Fe3C is confirmed by EDS analysis of white spots, which exhibits iron and carbon peaks. There is also evidence of chromium, silicon, and magnesium in other locations. The Vickers hardness of the sample as obtained was 416 HV however it was reduced to 240 HV after precipitation. Following with flame hardening, the material's surface hardness is increased to 600 HV. Consequently, the material has a hard surface and a tough core. As a result, the material has a ductile fracture rather than brittle fracture.
