CUTTING ELEMENT FOR A SAW CHAIN AND METHOD FOR THE PRODUCTION THEREOF
收藏资源简介:
The invention relates to a cutting element (11) for a saw chain and to a method for the production thereof. The cutting element according to the invention comprises a carrier part (16) formed from a break-proof steel alloy and a cutting part (17) welded to the carrier part (16) along a welded connection (18) and formed from a high-speed steel, wherein the steel alloy of the carrier part (16) is a tool steel, which has the following composition (in wt.%): carbon (C) 0.4 to 1.0, silicon (Si) up to 1.8, manganese (Mn) up to 0.6, chromium (Cr) 4.5 to 12, molybdenum (Mo) up to 3, vanadium (V) up to 2, iron (Fe) and the rest being melting-related accompanying elements and impurities; and, in the hardened state obtained by hardening at a suitable temperature above the austenitisation temperature of the high-speed steel, the steel alloy of the carrier part (16) has a hardness of greater than 600 HV and a tensile strength of greater than 2000 MPa.
