Intro: WHAT ARE THE TREATMENTS?Induction hardening and flame hardening are methods for hardening the surfaces of components, usually in selected areas, by the short-time application of high-intensity heating followed by quenching. The heating and hardening effec

Intro: WHAT ARE THE STEELS?Tool and die steels are covered in BS 4659:1989, although both American nomenclature and a variety oftrade names are also in use. Available in high-quality grades, these specifically-designed steels can be groupedbroadly according to t

Intro: Surface hardening of carbon steel by high frequency induction heating (HFIH) produces a considerable increase in its resistance to stress corrosion [1, 2]. The magnitude of this increase depends on the depth of surface hardening, on the strength of the sp
