E19 PRECISION PARTS - MATERIAL DESCRIPTION HZ = Hard-coated Tooling Components for High-Performance HZC Composite Vapour Deposition (CVD) TIC-TIN Coating Carrier materials: High-speed steels Material no. 1.3207, 1.3343, etc. Cold steels Material no. 1.2379, 1.2436, etc. Due to the risk of distortion, a coating should not be applied to thin tools with a streamlined size of l/d = 20:1. In addition, we cannot accept any liability for distortion for any other parts. Characteristics: The titanium carbide substrate provides a pressure-resistant bond with the carrier metal, while the outer layer of titanium nitride offers the well-known advantages of optimum tribologic behaviour in contact with the stamping stock. By virtue of its outstanding wear resistance, the TIN-layer largely eliminates seizing and cold welding prob- lems in stamping. Surface hardness approx. 3500 HV 0.05 Layer thickness approx. 5 - 8 μm. Application area: All tooling components subject to high demands on wear resistance and performance, especially punches in progression/combination tools, as well as cold extrusion punches etc. TIC-TIN = material code number = "5" e.g. Order no. = 223.5. ... HZN PVD titanium nitride TIN Carrier materials: The TIN-coating offers excellent frictional characteristics but its compressive strength remains inferior to TIC-TIN deposits. Option for partial coating. Surface hardness approx. 2300 HV 0.05 Layer thickness 2 - 4 μm; < Ø 2.0 = 1.5 μm ± 20 % HSS Material No 1.3207 and 1.3343 etc. HCHC Material No 1.2379 Other HCHC-steels are of conditional suitability. Characteristics: The TIN-coating offers excellent frictional characteristics but its compressive strength remains inferior to TIC-TIN deposits. Option for partial coating. Surface hardness approx. 2300 HV 0.05 Layer thickness 2 - 4 μm; < Ø 2.0 = 1.5 μm ± 20 % Application area: Tooling for thin stamping stock such as cold rolled spring steel, zinc-galvanized sheet and strip, copper-beryllium bronze, German silver, and solenoid lamination steels. Note that the ratio stock thickness to punch point diameter should not exceed 1:3. TIN = material code number = "0" e.g. Order no. = 223.0. ... HM = Tungsten Carbide Characteristics: Hard-sintered carbide on WC-basis and of recognized properties; produced by powder-metallurgic processes, FIBRO's exclusively used HIP-densified carbide exhibits much enhanced flexural strength and reduced residual porosity. Application area: Diecomponentsforhighestperformanceandverylargestampingvolumes–foraltogetherultimatedemandsontoollife. HM = material code = "9" e.g. Order no. = 270.9. ... NWA = Nitrided hot-work tool steel Material No 1.2344 or similar. Characteristics: Chrome-Molybdenum-Vanadium hot working die steel; core strength: > 1400 N/mm2; temperature resistant up to 650 °C; surface hardness (nitrided) ≥ 950 HV 0.3. Application area: Ejector for die casting and injection moulds. NWA = material code number = "8" e.g. Order no. = 237.8. ...
