The surface quality before chroming guarantees the quality of chromed bars. That’s the reason why at Uranie International, the operations to prepare the polished and ground bars before plating are meticulesly performed.
Purchased with a stock allowance hot rolled bars are peeled to remove surface steel defects, improve the geometry and calibrate to requested size.
Straightening is performed twice, before and after the peeling to guarantee perfect straightness.
Heat treatment induction hardening (optional)
The surface hardness is improved with an excellent control of the hardness depth and of the hardness grade, thanks to a fully automatic heat treatment machine, taking into account the different parameters like the steel grade, the diameter and the customer’s technical specifications.
Grinding and polishing
These operations performed in-line on centerless grinding machines allow to reach the perfect dimensional precision and surface finish.
