For reinforced polyamides, DOMO recommends the use of steel with a high content of carbon, and purified for polishing, to avoid or limit abrasion. For example: X38CrMoV5-1 (EN Norm) – 1.2367/1.2343 (DIN Norm) or X160CrMoV12 (EN Norm) – 1.2601/1.2379 (DIN Norm).
🎯 Typical Applications
Metal replacement, structural parts
Drive pulleys, guide wheels
Housings, transmission parts
High-strength structural components
