Abstract: Shaft failures often occur due to incidents. Incidents occur because the components used by the Go- Kart shaft must use lightweight materials so that the shaft works faster. The purpose of this study is to determine the strength characteristics of the Go-Kart rear wheel shaft on mechanical properties with ASTM A414 Grade A steel material after bending test and impact test. whether there is an effect of Go-Kart rear wheel shaft temperature with ASTM A414 Grade A steel material on toughness and curvature after going through the normalizing process and tempering process. The method was carried out using the heat treatment process method, three-point bending testing, and the Charpy Impact Test method. The lowest impact price value is obtained in the normalizing process of 800 ° C and the tempering process of 250°C, namely in the specimen (A3) which is 0.059 joules / mm2. The lowest three-point bending test results obtained by Specimen C3 with a normalizing process of 900°C and a tempering process of 350°C, amounting to 2059.26 N/mm2. The highest impact price value is obtained in the 850°C normalizing process and 300°C tempering process, namely in specimen (B2), which is 1.153 joules/mm2. The results of bending tests with a normalizing process of 800°C and a tempering process of 250°C (A1) and a normalizing process of 850°C and a tempering process of 300°C (B1), have the largest bending strength value, which is 2647.62 N/mm2.
