Hard Crom
Hard crome plated rods
Romanian hard crome; Hard crome coated steel bars that are induction hardened
A choice for hydraulic applications in the road and construction industry. Hard crome placed on the surface that has been induced prevents scratches and damage on the surface of the rod due to environmental factors such as dust and stones in transit and will increase the life of the cylinder.
