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.

Heat treatment of steel W.Nr. 1.2316 HH

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
