Abstract

Steel binding rings are commonly used in pre-stressing the cemented carbide (WC) dies for use as pressure containers in high-pressure equipment. These rings are generally made of high strength steels in hardened and tempered condition. They are interference fitted to generate required compressive stress on the WC dies. Failure of such a steel binding ring of a belt apparatus used for synthesizing diamond has been investigated. The fracturing of the ring was found to be due to stress corrosion cracking. The corrosion was found to have initiated at a mechanical dent in presence of NaCl corrosive agent. A detailed analysis of this investigation is reported in this paper.
