ANALYSIS OF TENSILE STRENGTH IN CRYOGENICALLY TREATED EN8 STEEL

Abstract

In an effort to achieve more economical machining, a tensile strength analysis of cryogenically treated EN8 steel i being conducted.The material is heated to a very high temperature and then quenched in oil to cool it down in the traditional heat
treatment procedure. A substance may be subjected to the Cryogenic Treatment, which comprises subjecting it to temperatures as low as -190oC to -273oC while it is confined in a chamber filled with liquid nitrogen.This study compares the effects of standard heat treatment and deep cryogenic treatment on the tensile strength of EN8 steel. Studies have indicated that a thorough cryogenic treatment of EN8 steel greatly improves the material's tensile strength.
