Abstract
The strong correlation between the strength and the coersive force of steel has been observed by many scholars of magnetism. The non-destructive measurement of steel strength by this correlation has been taken up from time to time by several students. However, the use of this measurement of steel strength has not been found practical in steel mills. Needs for such measurement of steel strength have been increasing in the steel industry because of the increasing processing speeds and the adoption of continuous process.
The aim of this paper is to confirm the limitation and applicabilities of this measuring principle. The paper presents important design considerations for different grades and shapes of steel products.
