摘要： A metal strip and a process for manufacturing such a metal strip are disclosed. In order to be able to reproducibly manufacture a durable metal strip, it is proposed for a butt seam to extend essentially between a first cladding layer of a first strip transverse portion and a second strip transverse portion.

摘要： Cutting tool for flat materials. The cutting tools includes a band-shaped base body which has on one longitudinal side a working region with cutting teeth and on an other longitudinal side a supporting region with a supporting surface. The cutting teeth are formed with tips and include cutting sides emanating from the tips at an angle a to one another. In a longitudinal direction of the working region, the tips of adjacent cutting teeth have different distances to the supporting surface.

摘要： The invention relates to a method and to an apparatus for producing a steel strip, in particular a steel strip having a bainitic microstructure, such as for example a spring steel strip or a punching tool, wherein the steel strip is made to pass continuously through the following treatment steps: austenitization of the steel strip at a first temperature above the austenitization temperature; quenching of the steel strip, by means of a gaseous quenchant, to a lower, second temperature selected in accordance with a desired steel microstructure. According to the invention, the gaseous quenchant is conducted onto the steel strip in such a manner that uniform cooling is achieved over the width of the steel strip.

摘要： A cutting member for a saw chain and a method for the production thereof, the cutting member comprising a support part made of a steel alloy and a cutting part welded to the support part along a welding connection made of a high speed steel. The steel alloy of the support part is a tool steel that has the following composition (specifications in % by weight): 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 accompany elements caused by melting and impurities as the remainder. The steel alloy of the support part in a quenched and tempered state has a hardness of more than 600 HV and a tensile strength of more than 2000 MPa as a result of curing at a suitable temperature above the austenitizing temperature of the high speed steel.-

摘要： A method for producing a primary material for a cutting tool, for example a primary material for a saw blade or a saw band, in which a band-shaped carrier of a metal carrier material and a wire of high-speed steel are continuously brought together along a lateral edge of the band-shaped carrier and transported into a welding device and the band-shaped carrier is welded to the wire along the lateral edge of the carrier to produce a bimetal band. The band-shaped carrier and the edge wire are welded to one another by at least a first welding device, which is arranged on one side of the band-shaped carrier, and at least a second welding device, which is arranged on the opposite side of the band-shaped carrier.
