KCF Guide Pin With Special Size Used In the Automatic Automobile Production Line
1 . Descriptions:
KCF Guide Pins and KCF Sleeves have been used in Resistance Welding applications for several decades. KCF is not a coating, it's the actual material. KCF Alloy is a Ferritic Stainless Alloy, which adds Chrome, Aluminum, and other special elements. When the KCF material is heat treated via a special high temperature process, the Aluminum comes to the surface and joins with oxygen to form Aluminum-Oxide, creating an insulated skin on its surface. This process makes the pins and sleeves very strong because it's all same the material, even the insulated surface. The surface of the KCF pin/sleeve is 20-30 micrometers thick.
If you need special specs, welcome to order custom-made.
Specifications are subject to change without prior notice due to constant improvements.
