HIGH STEEL CLEANNESS AS A CRITERIUM OF MA TERIALS DEVELOPMENT

High-purity steels open up new materials and application potentials fo r processing and product service. Improvements in purity and homogenei ty guarantee in particular more rational production of thin sheet and wire, one-piece design of complex bodywork elements, drawing and ironi ng of thin-walled cans and housings, efficient stranding of tire cords using the double-twist stranding principle, low-loss operation of ele ctrical generators and transformers, precise picture rendition in colo ur TV and monitor screen tubes, high service-lives for valve springs a nd rolling bearings, safe transmission of corrosive natural gases unde r arctic conditions and at great water depths, efficient functioning o f hydraulic power transmission and control systems, and zero-defect em bossing of patterns on paper surfaces.
