METALLURGY AND MATERIALS TECHNOLOGY OF HI GH-PURITY STEELS

Order of magnitude of the minimum O, S, P, N and H-2 concentrations ac hievable in steels. Methods of determining the degree of purity. Examp les of the metallurgical production and materials engineering properti es of high-purity steels: cold-rolled sheet for the manufacture of car bodies and beverage cans: highly decarburized high-purity ULC steels; soft magnetic NO-type electric sheet; steels for acid gas resistant l arge-diameter pipes and off-shore applications; high-strength steel co rd for car tyres; antifriction bearing steels with high fatigue streng ths. Conclusions with a view to the further development of steels and notes on the limits of the achievable degrees of purity.
