Material Description Surface Treatment
Material Description WS = alloyed tool steel Material No. 1.2210, 1.2516 or similar. A medium-alloy, strong tool steel with average edge-holding properties. HWS = High-Speed Working Steel with 12 % Cr Material No. 1.2379, 1.2436, 1.2601 or similar. A robust, strong and wear-resistant high-speed steel with good edge-holding properties. HSS = Superspeed Steel Material No. 1.3343 An abrasion-proof superspeed steel due to the content of either Tungsten or Molybdenum with high thermal stability. ASP = Superspeed Steel manufactured powder metallurgically Material No. ASP 23, ASP 30, ASP 60 Due to the homogeneous structure a higher fatigue strength and resistance to wear and abrasion is obtained. CPM = High Speed Steel manufactured powder metallurgically Material No. CPM 9 V, CPM 10 V Superspeed Steel manufactured powder metallurgically Material No. CPM Rex 4 Due to the high content of Carbon and Vanadium resistance to wear and abrasion and edge-holding properties is increased. Hard Material = Ferrotitanite or Ferro-Tic Material No. WFN, Type CM The even distribution of Titanium Carbide guarantees less corrosion and pitting and high wear resistance. Nitrided Hot-Work Steel = Material No. 1.2343, 1.2344 Cr-Mo-V alloy Hot-Work Steel with a core hardness of approx. 40 - 45 HRc and a surface hardness of approx. 950 HV 0,3. Surface Treatment Longer Exposure Times can be obtained with the following Surface Treatments: Nitriding suitable for: 1.2379, 1.3343, ASP 23, ASP 30, ASP 60, CPM Rex 4, CPM 10 V or similar. TIC Coating (CVD Process) Colour: silver suitable for: 1.2379, 1.2436, 1.3343 or similar. Due to diffusion of Titanium Carbide the surface hardness increases to approx. 3000-4000 HV 0,05 with great core strength. This process is, however, only suitable for larger diameters as from approx. 5mm. TIN Coating (PVD Process) Colour: gold suitable for: 1.3343, ASP 23, ASP 30, ASP 60, CPM Rex 4, CPM 9 V, CPM 10 V or similar. A layer hardness of approx. 2200-2400 HV 0,05 at a layer thickness of 2 -4 µm can be obtained. The low coating temperature (approx. 480 0C) permits the coating of tools with the minimum of tolerances. Partial coating is also possible. TICN Coating (PVD Process) Colour: grey suitable for: 1.3343, ASP 23, ASP 30, ASP 60, CPM Rex M 4, CPM 9 V, CPM 10 V or similar. The TICN layer combines the extreme hardness of a Carbide layer (TIC approx. 3000 HV 0,05) with the advantageous chemical properties and the favourable sliding behavious of the nitriding layer (PVD approx. 480 0C). Layer thickness is 3,0 - 5,0 µm. Microchrome Coating 9 (MCP Process) Colour: silver suitable for: 1.2376, 1.2436, 1.3343, ASP 23, ASP 30, ASP 60, CPM Rex M 4, CPM 9 V, CPM 10 V or similar. Chromium plating improves the roughness of the surface and increases surface hardness to more than 1000 HV (= 68 - 70 HRc). The procedure is suitable for very thin parts, as the layer thickness can be varied. 400 +49(0)40-797002-0 Fax +49(0)40-797002-22 Grades for steel bolts and screws Description system The most important mechanical characteristics regarding steelmade bolts are designated by means of a two-digit number combination, as per the following example: 8.8 The first fugure indicates 1/100 of the minimum tensile strength in N/mm2 stress area. For this example tensile strength 8 x 100 = 800 N/mm2. The second figure indicates the 10-fold relationship of the nominal yield stress ReL (or Rp 0,2) to the nominal tensile strength Rm (yield point relationship) . Minimum yield stress ReL _______________________________________ . 10 Minimum tensile strength Rm Multiplication of the two figures results in 1/10 of the minimum yield stress in N/mm2. For this example minimum yield stress 8 x 8 x 10 = 640 N/mm2. Mechanical characteristics of bolts according to grades Characteristics Grades Nominal value Tensile strength Rm in N/mm2 min. Nominal value Yield stress ReL in N/mm2 min. Stress at permanent set limit Nominal value Rp 0,2 in N/mm2 min.
