Cold Work Tool Steels

K110 is used for high-duty cutting tools (dies and punches), blanking and punching tools, woodworking tools, shear blades for cutting light-gauge material, thread rolling tools, tools for drawing, deep drawing and cold extrusion, pressing tools for the ceramics and pharmaceutical industries, cold rolls (working rolls) for multiple-roll stands, measuring instruments and gauges, small molds for the plastics industry where excellent wear resistance is required.

Powder-metallurgical produced cold work tool steel with extremely high wear resistance, good toughness and high compressive strength.

3rd Generation PM Technology

The latest generation of powder metal technology enables Bohler to manufacture a cleaner and finer powder then any other producer in the world today.  The result is a significant increase in toughness and a more uniform carbide distribution.

Air hardening cold work tool steel with good dimensional stability, high resistance to wear and good machining properties.

BÖHLER K305 is equivalent to AISI A2.

ADVANTAGES IN TOOL USE:

• Excellent adhesive wear resistance
• High compressive strength
• Easy to regrind
• High cutting edge retention
• Consistently high component precision
• Safety against breakage or failure in use
• Reproducible tool Parameters

EDRO S7 ESR is a chromium-molybdenum shock resistant steel characterized by high toughness and high impact resistance.

These benefits, coupled with the high wear resistance offer the molder low-maintenance, long-life molds for the greatest overall molding economy.

EDRO S7 ESR is produced using the ElectroSlag-Refining (ESR) technique, resulting in an extremely fine and consistent micro-structure with superior cleanliness.

BÖHLER K340 ISODUR, an 8% chromium steel, is produced using the electro-slag remelting (ESR) method. This by BÖHLER developed and proven remelting technology, ensures extremely low micro and macro segregations and gives the material the purity and homogeneity necessary for excellent performance in practice.

K353 is a universal tool steel for cold working applications, characterized by high hardness, high wear resistance and excellent toughness. K353 is a conventionally produced 8% Cr steel which combines very good machinability, good EDM properties and good dimensional stability.

BÖHLER K360 ISODUR is a further development of the 8% chromium steels and has been developed to meet the needs of our customers now more than ever before. A Remarkably high wear resistance together with good compressive strength makes this steel a real problem-solver.

Just as mountaineers need the best equipment to conquer the highest peaks, it‘s essential to use the best materials for your tooling to ensure trouble-free production and achieve outstanding tool life.

Three reasons why BÖHLER K390 MICROCLEAN is highly cost effective: Extremely high wear resistance, excellent toughness and very high compressive strength. The high-performance powder-metallurgy steel BÖHLER K390 MICROCLEAN is a reliable solution for your difficult cutting, die-cutting and cold forming operations, and it has a very good track record for applications in the plastics industry.

BÖHLER’s cold work tool steel K490 MICROCLEAN closes the gap in the material demands between wear resistance and the desired high toughness.

Highly stressed coining tools, cutlery dies, hobbing tools, cold shear blades for heavy – gauge material, plastic molds.

K720 is used for Tools (punches) and dies for blanking, punching and similar operations; threading and woodworking tools, machine knives for the pulp, paper and metalworking industries; measuring tools and plastic molding dies.

BÖHLER K890 MICROCLEAN – This powder-metallurgical cold-working steel has good toughness, very good compressive strength, and excellent fatigue strength.

Ideal for mills, spiral bits, and taps, broaches, cold-work tools. BÖHLER S600 is the most commonly used high-speed steel and is the starting material for our customers who deal with high-speed steel.
