PENGARUH MANUAL FLAME HARDENING TERHADAP KEKERASAN HASIL TEMPA BAJA PEGAS
Abstract: The main purposse of
this work were to study effect of manual flame hardening on the forging
steel. Manual flame hardening is the
surface hardening method using flame
and manual operation without automatic equipment. The
study of effect of
manual flame hardening
on the forging
steell done as
follows : annealing of
specimen, forging, and
followed by manual
flame hardening.
Material used in this work was car leaf spring. This research work
revealed that manual flame hardening increased hardness of forging steel from
717 HV to 866 HV. On the micro structure observation, martensit and ferrite
structure are formed on the specimen.
