X153CrMoV12

Properties :

High carbon and high chromium, ledeburitic 12 % Cr alloyed cold work tool steel, excellent abrasion resistance due to

a large volume of carbides in the microstructure, high cutting ability with edge holding properties, high compression strength, excellent deep hardenability and toughness properties, dimensional stability during heat treatment, high res-istance to softening at elevated temperatures. Suitable for nitriding and electrical discharge machining.

Applications :

High performance blanking, punching, stamping and cutting tools and dies up to 6 mm sheet thickness, thread rollings, chasers and dies, precision blanking dies, longitudinal and circular shear blades for plastic, paper and metal, cold form-ing and bending tools, tools for drawing, deep drawing and cold extrusion, hobbing tools, woodworking tools, milling cutters, reamers, broaches, pressing tools for the ceramics and pharmaceutical industries, cold piercers, measuring inst-ruments and gauges, rolling cutters and shaping wheels, cold pilger mandrels, beading, flanging and straightening rolls, plastic injection moulds, especially cutting tools of austenitic material when nitrided.
