Abstract: The present study shows that Chromium molybdenum steel 415 (CMB415) has historically been used for the production of gears by the leading international manufacturers due to its exceptional hardness and superior mechanical properties after carburization. However, in order to meet the demand for the reduction gearbox components, the limited availability of Chromium Molybdenum Steel 415 in India necessitated the need to explore alternative materials. Carbon 45 (C-45), steel 410 (SS410) and emergency number 19 (EN-19) are often used as alternatives which offer similar mechanical properties in India. As these materials are readily available on the Indian market, manufacturers experiencing shortages of SCM415 can consider them as a viable option. These materials shall be subjected to a series of tests, such as tensile, hardness and microstructure tests, before and after two different thermal treatment procedures to assess their suitability for use in the process. The EN 19, C45 and SS 410 were found to have different mechanical and microstructural properties as viable alternatives to SCM 415. C45, significantly higher than EN-19 and SS410, achieves a hardness of 61 HRC after induction-firing.
