Base material for the manufacture of plates of raw material for circular saws, cutters, grinders, reciprocating saws, as well as cutting tools and scratching.

摘要

Iron matrix for a saw, such as p. eg. a circular saw or a reciprocating saw, a cutter wheel, a cutting tool or scraping, made of a base material consisting of a steel cemented basis from its outer face, characterized in that the acerode base is cemented a base carbon content from 0.1 to 0.26% so that the steel base has at least from one of its outer faces enriched with 0.6 to 1.1% carbon area, which to be decreasing the carbon content becomes a cementless area, due to which, the base material has a sandwich structure, which is formed at least by a cemented zone and a cementless area.
