Keywords: Jominy test, AISI 1045 steel, Hardenability, Quenching ABSTRACT The development of heat treatment testing equipment is essential in metallurgical applications, especially for

determining the hardenability of steel. This study focuses on designing a portable Jominy test apparatus to evaluate the hardenability of AISI 1045 medium carbon steel, offering a more

practical and cost-effective solution. The apparatus was built with an angle iron frame (64 x 82 x 64 cm) and equipped with a 200-liter water drum and a Shimizu water pump (18 L/min flow

rate). Hardness testing was performed using the Rockwell B method (150 kgf load, 15-second dwell) on specimens subjected to three conditions: raw, water-quenched, and oil-quenched, after

heating at 900 °C for 30 minutes. The results showed hardness increases from 91.00 HRB (raw) to 101.33 HRB (water-quenched) and 100.33 HRB (oil-quenched), with water quenching producing

slightly higher values due to its faster cooling rate. The study demonstrates the effectiveness of the portable apparatus for evaluating AISI 1045 steel hardenability with advantages in

portability, cost, and reliability. Published 2024-12-30 How to Cite 1. Rahman, Arif Z, Suheri, Bahri Widodo S. Innovative Jominy Test Equipment for Evaluating The Hardening Of AISI 1045
