Abstract
Vacuum-melted steels are now going to be in practical use, and for bearing steel, which is to be produced in large scale, by vacuum arc melting method (the so-called Cons-el Arc melting method) should be more suitable rather than vacuum induction-melting method.
Therefore, the research for the material characteristics of Cons-el Arc melted bearing steel was conducted according to the inspection specification of Japan Bearing Society compared with the air-melted one.
As the results, it was found that the Cons-el Arc melted steel was much superior to the other in the macro-structure, compressive breaking strength, surface defects and so on.
