E19 subject to alterations Ground precision parts – materials and coatings Carrier material = Hot-work tool steel, nitrided (NWA) Material no: 1.2344 or similar Characteristics: Hot-work tool steels have particularly hot hardness, temper resistance, toughness and thermal shock resistance. Hot-work tool steels are used for temperatures above 200°C in continuous operation. The nitrogen nitrides diffused in during the nitriding treatment give the tool part even greater resistance to wear and the best possible protection against cold welding. NWA = material code number = "8" e.g. Order no. = 237.8. ... Carrier material = Carbide (HM) Characteristics: Powder metallurgically produced WC-based carbide. Carbide is characterised by high hardness and resistance to wear, resulting in excellent tool service life. Higher flexural strength and residual porosity through post-compaction in the HIP procedure. HM = material code = "9" e.g. Order no. = 270.9. ... Coating material PVD titanium nitride TiN Characteristics: The titanium nitride coating TiN is a versatile "all-rounder" among coatings. Completely food safe, chemically resistant and biocompatible. Surface hardness approx. 2300 HV 0,05 Layer thickness 2 - 4 μm Friction value (dry steel) 0,4 Application temperature max. 600°C Application area: Drawing, punching and forming tools for iron and steel plates. TIN = material code letter "A" (carrier material HSS) e.g. Order no. = 2209.A. ... Coating material PVD titanium carbonitride TiCN Characteristics: With the titanium carbonitride coating TiCN, the tool service life can usually be significantly increased again compared to TiN-coated tools due to a very good resistance to wear. Surface hardness approx. 3000 HV 0,05 Layer thickness 2 - 4 μm Friction value (dry steel) 0,4 Application temperature max. 400°C Application area: Drawing, punching and forming tools for high-alloy and low-alloy sheet metal and stainless steel. TICN = material code letter "B" (carrier material HSS) e.g. Order no. = 2219.B. ... Coating material DLC (a-C:H) Characteristics: The "Diamond-like-carbon" layer DLC is particularly slippery, very hard and chemically resistant. Cold welds are avoided and tinsel formation is greatly reduced when cutting aluminium sheets. Surface hardness up to 2300 HV 0,05 Layer thickness 1 - 3 μm Friction value (dry steel) 0,1 - 0,2 Application temperature max. 300°C Application area: Drawing, punching and forming tools, especially for aluminium processing DLC = material code letter "C" (carrier material HSS) e.g. Order no. = 2249.C. ...
