Our cemented carbide grades with nickel binder and chrome additive are extremely corrosion-resistant and are generally not attacked by acids, waste water or organic Solutions. They are therefore suitable for all application in wear protection in the chemical industry, as spray nozzles in plastic manufacturing and for applications in the food processing industry where HARTMETALL ESTECH, as one of the only two companies worldwide, has a certificate from the US-FDA which confirms the safety of these nickel grades in the food industry.
Upon request, most of our nickel hard metals can also be delivered completely nonmagnetic; e.g. for pressing tools in the manufacturing of magnets.
使用镍粘结剂以及增加了铬添加剂的硬质合金牌号极耐腐蚀，一般不受到酸、废水或有机溶剂的侵蚀。因此，这些牌号适合化学工业的耐磨零件，比如在塑料制造业和食品加工行业里的喷嘴。在全世界的硬质合金公司里，只有两家公司从美国 FDA 获得食品工业的硬质合金安全牌号的认证，伊斯泰克硬质合金公司就是其中之一。
如果需要，我们的含镍硬质合金牌号可以做到完全无磁，比如在磁铁制造中的冲压工具。

Grade | Nickel content %w/w | Properties and recommendations
|
RCS12 | 6.0 | Our hardest nickel binder cemented carbide grade is very wear resistant; however not suitable for applications where there is risk of breakage. Use in guides, mixing rods, slide rings, spray nozzles, cutting blades and other wear parts in laboratories, chemical industry, pump construction, grinding and mixing systems and In plastics processing(GFP). 是硬的镍基硬质合金牌号，非常耐磨; 但是不适合有破裂风险的用途。用于导轨，搅拌棒、 滑环、 喷嘴、刀片和其他耐磨零件部件，适用领域为实验室、化工、泵，研磨和搅拌系统和塑料的制备。 |
RCS17 | 8.5 | Similar area of application as RCS12; however, the nickel hard metal grade RCS17 is slightly more break resistant. Use in guides, mixing rods, slide rings, spray nozzles, cutting blades and other wear parts in laboratories, chemical industry, pump construction, grinding and mixing systems, in plastics processing and in the food industry. 应用领域的类似于RCS12; RCS17相对更耐断裂。用于导轨，搅拌棒、 滑环、 喷嘴、刀片和其他耐磨零件部件，适用领域为实验室、化工、泵，研磨和搅拌系统和塑料制备以及食品工业。 |
RCS24 | 12.0 | This newly developed grade of nickel binder cemented carbide has a significantly higher binder content than the two previously mentioned grades. Thus, it is especially suitable for applications with a risk of breakage. Primary applications include slide rings, shaft sleeves and sealing elements in the chemical industry, in the pump construction and in the food processing industry. It is also used for mixing and grinding systems of materials with highly inhomogeneous composition. 这种新开发的镍基硬质合金比之前的牌号有更高的粘结剂含量。因此，它特别适合有破裂风险的用途。主要应用包括化工、泵和食品加工行业的滑环、 轴套和密封元件。它也用于高度非均匀组成的系统的混合和研磨。 |

RCN | 8.0 | Standard nickel grade with fine grain, good temperature resistance, good solder-ability. Similar uses as RCS 17. Additionally suited for guides in welding technology. 镍基硬质合金的细颗粒标准牌号。耐热性能好、 具有良好的焊接能力。用途类似于 RCS 17。另外适合焊接。 |
RCFN22 | 11.0 (Nickel/ Chrome) | This nickel binder cemented carbide has a high chrome content. It is the most corrosion-resistant of all our hard metal grades and is fully nonmagnetic. Use in slide rings and sealing elements in the pump construction and in the chemical industry for highly corrosive Liquids. An additional application is pressing tools in the magnet industry. 这个镍基硬质合金含有较高的铬，它是耐腐蚀的牌号，并且完全无磁。用于存在高度腐蚀性液体的泵和化工中做滑环和用密封件。另外在磁铁行业用作冲压工具。 |
RCM30 | 15.0 | Due to its increased nickel content and the medium grain size, we use RCM30 in particular as a highly breaking resistant, relatively impact and fracture resistant, temperature-resistant and easily solder nickel binder cemented carbide grade. Application especially in large slide rings, sealing element and dies. The corrosion resistance of this grade is sufficient for most applications in the chemical industry and pump construction. RCM30有比较高的镍含量，颗粒度为中等，用于需要高温耐破裂，抗压、抗断裂、 耐高温、 易可焊性的场合。尤其适用于大型滑环，密封元素和模具。这种等级的耐腐蚀性能能够满足大多数的化工和泵工业。 |
