Abstract

Annealing is a heat treatment of metal with slow cooling to remove internal stresses or to reduce the crystal structure (involves heating above a critical temperature. Hardening is a heat treatment process carried out to produce a hard workpiece. Tensile testing is one of the mechanical tests that most widely used in industry and in education because of the ease of analyzing the data obtained and obtaining information about the mechanical properties of a material.In this study using 304 stainless steel wire with a diameter of 1 mm, aims to determine the maximum load limit, maximum stress and strain From the annealing and hardening processes, the results obtained after the annealing process 1 obtained a maximum load of 72.7 kg, tension 92.611 kg/mm2, strain 0.184, anneling 2 maximum load 75.7 kg, stress 96,433 kg/mm2, strain 0.267, annleng 3 maximum load 70.6 kg, tension 8 9.936 kg/mm2, strain 0.326.Hardening 1 maximum load obtained 72.5 kg, stress 92.356 kg/mm2, strain 0.176, hardenig 2 maximum load 73.5 kg, stress 93,630 kg/mm2, strain 0.252, hardening 3 maximum load, 73.3 kg, strain 93,376 kg/mm2, strain 0.213. And raw material 1 obtained a maximum load of 134.1 kg, stress 170.828 kg/mm2, strain 0.022, raw material 2 maximum load 129.4 stress 164.841 kg/mm2, strain 0.013, raw material 3maximum load 128.8 kg, stress 164.076 kg/mm2, strain 0.01
