你想生产什么?
For standard applications
Screws with high surface hardness
Screw < Ø 50 | 34CrAlNi7-10 (1.8550) nitrided | |
Screws > = Ø 50 | 34CrAlNi7-10 (1.8550) nitrided |
Depending on the application, screws can receive additional treatment, e.g., nitrided, chrome-plated, or PVD-coated.
These are recommendations; as required, some raw materials may need alternative treatment.
For plastics with low filler content
Plated version for high resistance to abrasive wear on flight surfaces. Corrosion and abrasion-resistant substrates depending on the application.
Screws < Ø 50 | X 153CrMoV12 (1.2379) through-hardened | |
Screws > = Ø 50 | 31CrMoV9 (1.8519) R331 |
Depending on the application, screws can receive additional treatment, e.g., nitrided, chrome-plated, or PVD-coated.
These are recommendations; as required, some raw materials may need alternative treatment.
For plastics with filler content of >30%
Maximum resistance to abrasive, corrosive and adhesive wear. Plated version to protect the complete flight surface. Suitable for applications to withstand extreme wear conditions.
Screw < Ø 50 | PM-HIP through-hardened | |
Screws > = Ø 50 | 38CrMo16 (1.2316) or 31CrMoV9 (1.8519) R341 |
Depending on the application, screws can receive additional treatment, e.g., nitrided, chrome-plated, or PVD-coated.
These are recommendations; as required, some raw materials may need alternative treatment.
For special applications
We offer special alloys for the production of complex products, such as PTFE, PFS, FEP.
问题所在
磨损保护不足会成为一个严重的问题。螺杆和机筒上的材料损失会导致内部泄漏和工艺上的波动。这对产品性能有负面影响。在最坏的情况下,磨损甚至会导致生产停顿,危及你的盈利能力。
延长生产时间
市场上种类繁多的合金可能令人困惑。我们的专家会指导你进行选择,并与你合作,找到最适合你生产的合金。
