W.NR. 1.2316HH
Characteristics
Medium alloyed cold work steel with good hardening capacity, high wear resistance, dimensionally stable during heat treatment. Its applications are small tools for cutting and punching, shear knives, thread rolling tools, measuring tools, wood working tools.
Suitability
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. Cutting tools such as broaching thorns, profile knives and difficult-shape milling machines for lower cutting speeds and for treatment of nonmetallic abrasive materials. Further the steel is applied in the production of highly stressed molds and their components for working of plastic and powder substances, glass, porcelain and ceramic materials. By tools for crushing and grinding it is used for hammers of crushers and jaws for mild grinding and crushing.

| Way | Temperature [°C] | Procedure | |
|---|---|---|---|
| Forging | 850-1050 | Cool slowly in calm air or better e.g. in dry ash or other thermally-insulated material | |
| Soft annealing | 830-860 | Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in the furnace | |
| Annealing to lower tension | 600-650 | Warm 1 to 2 hours and cool slowly in the furnace | |
| Hardening | 1000-1080 | Cool in oil, air or salt bath at the temperature of about 500-550°C | |
| Tempering | 100-550 | Cool in air, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart | |
