Cold work tool steels

It is a high-carbon tool steel that consists of 12% Chromium. It has high wear resistance and toughness. This type of steel (AISI D2, DIN standard 1.2379) is the most common steel in cold work applications worldwide.

It is a high alloyed tool steel with a very broad property profile. It is also a very good steel for all types of surface treatments. This combination means that SLEIPNER is an extremely versatile conventional tool steel for medium run cold work tooling.  

A medium alloyed tool steel with a good resistance to both the abrasive and adhesive types of wear as well as good resistance to cracking. This combination makes RIGOR an all purpose tool steel for medium run cold work applications.

Calmax is a medium alloyed tool steel suitable for short and medium run tooling in applications where a very high chipping resistance is required. The property profile makes Calmax a robust cold work tool steel for heavy duty blanking and forming. 

Tool steel suitable for medium and long run tooling in applications where a very good abrasive wear resistance is needed. BOHLER K100 contains large carbides which are advantageous for abrasive wear resistance.  

A general purpose oil hardening tool steel with good machinability but lower wear resistance. Suitable for wear plates,cutting blades,tools, punches and dies. Gauges and measuring tools;Forming tools.

Air hardening alternative to this is Bohler K305 or Uddeholm Rigor.

Precision ground to provide a decarburisation free surface, plus a high wear resistance after heat treatment, making it ideal for a multitude of uses and applications: dies, press tools, punches, gauges, cams, jigs, machine, knives and marking devices.  

Oil hardening tool steel with good machinability. Suitable for making twist drills and taps, ejectors, punches,reamers,counter sinks,engraving tools, shafts for instruments and low strength application if used in the as supplied annealed condition. Supplied to tolerance ISO h8, ground and polished.

Cold work tool steel suitable for the manufacture of light duty Twist drills and taps, ejectors, punches, reamers, counter sinks engraving tools, metal cutting saws.
Supplied to tolerance ISO h8, ground and polished in fixed lengths of 1000 or 2000 mm.

Suitable for applications where toughness and chipping resistance are the dominant requirements, and the wear resistance is not so high. Heavy-duty cutting tools, punches and dies. Shear blades for heavier gauge material. Coining tools, cutlery dies, hobbing tools. Cold rolling dies for forming thicker sheet metal.

Also used for engineering components which require high strength and toughness.

This material is supplied in the annealed condition and must be heat treated to the appropriate condition for the intended application.

Unimax is a high hardness electroslag remelted tool steel which provides great wear resistance even over extended time at elevated temperatures. This product is suitable for coating and nitriding. Unimax performs very well in precision forging, hot stamping and moulding of reinforced plastics.

Shock resisting oil hardening cold work tool steel. Cutting tools for heavy plate, cold punches, shank tools for pneumatic equipment.

Cold work tool steel possessing good resistance to abrasion, and excellent elasticity.

Clamping tools (e.g. collet chucks, arbors), shear blades, punches, screwdrivers, nail sets, expanding mandrels, ejector pins, center punches, nail punches.

Suitable for applications where abrasive and adhesive wear are the dominant requirement, and resistance to chipping is also required. Cutting tools, punches and dies. Shear blades for soft adherent materials such as austenitic stainless, mild steel, copper, aluminium and thicker gauge high strength work material Thread rolling dies. Tool for drawing, deep drawing and cold extrusion. Cold rolling dies for forming sheet metal. 

Suitable for applications where increased abrasive wear resistance is required  compared to Vanadis 4, and resistance to chipping is also required.Suitable for cutting tools, punches and dies. Shear blades for soft adherent materials such as austenitic stainless, mild steel, copper, aluminium and thicker gauge high strength work material.Thread rolling dies. Tool for drawing, deep drawing and cold extrusion. Cold rolling dies for forming sheet metal. Fine Blanking tools.

Cutting tools(dies,punches) for normal and precision blanking.Extrusion tooling(cold and warm/semi-hot forming). Drawing and deep-drawing tools. Stamping tools.Thread rolling tools.Cold pilger rolling mandrels. Compression moulding dies for the processing of sintered parts. Knife applications. Extruder cylinders and conveyor screws. Mould inserts. Injection nozzles. Backflow check valves.

A greatly improved and more efficient cold work tool steel compared with other commonly used PM steels such as the AISI M4 (PM) types. toughness is more than doubled with a similar wear resistance. It can be used in a wide range of applications: Blanking and punching industry. Cold forming applications. Industrial knives.

For tooling which requires a high edge stability and therefore a high capacity for plastic yield and a high fatigue strength e.g. cutting and blanking,fine cutting,cold forming,cold massive forming, powder compaction,warm forging at lower temperatures.
