Abstract

PURPOSE: By making use of a close relationship with the JIS standard, the tensite and bending strength of 20ϕ cylindrical testpieces with the same composition can be determined, and from then measurements mechanical properties of cast iron can be accurately and simply determined at pre-heating.
