Surface coated steel strip for complex forming processes
Phosphate-coated bonderized steel strip
We can refine our case-hardening steels and DC grades with a phosphate layer upon request. This is particularly beneficial when high-tensile materials are required which still need to be formed to manufacture the end product. The so-called lubricant layer reduces friction during the forming process, making it possible to form harder materials as well. The lubricant layer also significantly reduces tool wear and enables complex forming operations.
Many customers greatly value the excellent formability of phosphate-coated steel strip for the production of complex stamped, bent and formed parts such as needle bearings and bucket tappets in wear-freevalve control systems in automobile manufacturing. Our phosphate-coated steel strip is also used in chainsaw and electric drill components and in the powertrains of utility vehicles.
Phosphated surfaces - the lubricant layer
The lubricant layer is manufactured in several steps. It ensures optimal material formability and longer tool service lives.
