H11/1.2343 tool steel is a 5% chromium hot work steel that is characterized by excellent impact toughness. It contains less vanadium than the widely-used H13 tool steel. This provides for the higher toughness, with some reduction in wear resistance and temper resistance. H11 tool steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment. The steels are subjected to minimal distortion during hardening due to their balanced alloy content. It has good resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock when water cooled in service. H11 tool steel is recommended for hot tooling applications where maximum resistance to cracking is required. Such applications include hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling.
H13/1.2344 Chromium Hot-work Steel is widely used in hot and cold work tooling applications. Due to its excellent combination of high toughness and fatigue resistance, H13 is used more than any other tool steel in tooling applications such as die casting dies for zinc, white metal, aluminum and magnesium. It is also widely used for extrusion dies, trimmer dies, gripper dies, hot shear blades, casings, and other similar hot work applications.
Characteristics: hot work tool steel for oil or air hardening to develop high hot strength, retention of hardness, and heat checking resistance. Applications: highly stressed hot work tools, such as mandrels, dies and containers for metal tube and rod extrusion; hot extrusion tools; tools for manufacture of hollows, screws, rivets, nuts and bolts. Die casting tools, forming dies, die inserts, hot shear blades.
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.

This steel shows good dimensional stability at the heat treatment, suitable for hardening to the secondary hardness (the possibility of nitriding). Further the steel is very difficult to sharpen, it works at the heat with difficulties and has a rather difficult workability in the annealed state. D2/1.2379 is suitable for making tools for cold cutting, i.e. all kinds of tools with the long durability for cutting on presses and punching of materials of smaller thicknesses and materials of high hardness (especially difficult-shape tools for cutting, e.g. transformer metal sheets and metal sheets from stainless steels), knives for plate shears for the sheet and strip steel up to thickness of 10 mm of sheared material, knives for wire cutting etc. Tools for mechanical working such as e.g. smaller girders and tools for drawing, all kinds of tools for transformation and punching of materials. Further the steel is suitable for simple and symmetric tools for pressing and pushing, tools for thread rolling, plain and profile rolls, swages and also for cold work.
