HeatTreatingProcessesand RelatedTechnologyIntroduction Heat treating is defined as heating and cooling a solid The focus in this chapter is on heat treatments associated with getting the desired result. and the technology. 2 / Heat Treater’s Guide Fist, key components abstracts on
Through heat treating, we can make a metal harder, stronger, and more resistant to impact. Also, heat treating can make a metal softer and more ductile. The one disadvantage is that no heat-treat-ing procedure can produce all of these characteristics in one operation.
Heat Treatment Heating a metal or alloy to various definite temperatures, holding these for various time durations and cooling at various rates. Purpose of heat treatment: 1.To remove or relieve strains or stresses induced by cold working or non- uniform cooling (for example welding): Annealing
Heat Treatment to Form Martensite (Quenching) Consists of two steps: 1. Austenitizing – heating the steel to a sufficiently high temperature for a long Carbonitriding Lowcarbon steel C and N Heat steel at 700-800 °C (1300-1600 Surface hardness 55 to 62 HRC. Bolts, nuts, gears °F) in an atmosphere

2 Heat Treatment Processes It is a process of heating cycles where the metal is subjected to controlled temperature changes in solid state. 5 Hardening Processes for Gears There are mainly following 3 processes which are used for hardening the gears (1) Through Hardening (2) Case
of steel before heat treatment 86-13 • Cementite – Carbide of iron (Fe3C) which is hardener in steel • Austenite – Solid solution of carbon in iron, which exists between lower and upper critical temperatures • Martensite – Structure of fully hardened steel obtained when austenite quenched – Characterized by
