Following hardening, the work-piece is in its hardest but brittle condition and therefore requires a further heat treatment (tempering, or hardening), to get the optimum balance of properties. This consists of reheating the work-piece to a lower temperature and holding for a specific time. The choice of time and temperature depends on the amount of tempering or ‘softening back’ the work-piece requires.
Hardening of engineering steels (in the carbon range 0.3 to 0.55%, ranges between 800 and 900°C.. Tempering is generally carried out between 400 and 800°C. Tools made from higher alloy steels are also hardened and tempered but require greatly higher temperatures, up to 1200°C. for hardening and multiple tempering treatments are often required.
For any steel analysis and hardening medium there is a section size, above which the work-piece will not satisfactorily through harden. This is known as the limiting ruling section and is the main design parameter that needs to be considered, in combination with the geometry and property requirements of the work-piece, when specifying a hardening and tempering.
Forever has offered various bar hardening and tempering system solutions since 2004. Our engineering expertise in developing induction heating equipment solutions has been applied by many automotive ,shaft or sucker rod manufacturers worldwide.
