Claims42
A composite tool comprising a supporting part of a metallic material having a first composition and at least one working part of a metallic material having a second composition which is different from the first composition, which parts are joined by a metallic connection, wherein the supporting part is made of a tenacious iron-based material and the at least one working part is made of a precipitation hardenable iron-cobalt-tungsten alloy.
A process for the manufacture of a composite tool comprising a supporting part and at least one working part, which process comprises joining a supporting part made of a tenacious iron-based material and at least one working part made of a precipitation hardenable iron-cobalt-tungsten alloy by a metallic connection.
A method of cutting an article comprising an austenitic alloy, wherein the article is cut with a composite tool comprising a supporting part made of a tenacious iron-based material and at least one working part made of a precipitation hardenable iron-cobalt-tungsten alloy, the supporting part and the at least one working part being joined by a metallic connection.
