Cold Work Tool Steel

1.2550 Tool Steel is an alloy shock-resisting tool steel, which is suited for both hot and cold work applications. The tungsten content of this tool steel grade confers fatigue resistance, the chromium content gives depth of hardness and resistance to abrasion.

1.2550 tool steel is suitable for cold work tools subject to heavy shock and uneven loading. This steel is also used with great success for chisels and punches required for heavy work on hard and tough materials.
It is suitable for hot work applications where high fatigue strength in combination with medium hot hardness is desirable. Tools made from this tool steel can be water cooled in service with little risk of cracking.

1.2601 tool steel with high wear resistance against abrasive and adhesive, good toughness, edge-holding ability and compression strength, low distortion, non-deforming, full hardness with air hardening in any dimension, suitable for bath nitriding.
1.2601 tool steel applications mainly for making high performance blanking, punching, stamping and cutting tools and dies up to 6mm sheet thickness, thread rollings, chasers and dies, cold forming and bending tools, precision blanking dies, longitudinal and circular shear blades for plastic, paper and metal, milling cutters, reamers, broaches, hobbing tools, tools for drawing, deep drawing and cold extrusion, woodworking tools, pressing tools for the sinters, ceramics and pharmaceutical industries, cold piercers, measuring tools, rolling cutters and shaping wheels, cold pilger mandrels, flanging, straightening and beading rolls, trimming and splitting dies, tools for the cold manufacture of screws, nuts and rivets, plastic moulds.

1.2767 tool steel is a higher carbon version of the standard 4.25% nickel oil hardening steel. It is a good quality tool steel that achieves high impact and compressive strength and is suitable for applications demanding extra wear resistance. With its characteristics of good full hardenability, good polishability and excellent toughness this cold work tool steel specification is widely used for plastic mould applications.
1.2767 tool steel typical applications and components include plastic moulds, cutlery dies, shear blades for heavy gauge material, cutting tools, drawing jaws and highly stressed coining tools.

Description
Special cold work tool steel, air or oil hardenable with highest toughness.

Applications
Forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers, etc.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.86

Soft Annealing
Heat to 610-850oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 295.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Harden from a temperature of 880-910oC followed by air or oil quenching or warm bath quenching 180-220oC. Hardness after quenching is 56 HRC.
