We are able to tailor steel properties such as strength, machinability, formability and hardenability for the most common customer requirements.
The size of the drawn bar can also be tailored to specific needs. The result is that our customers receive a material that supports consistently high-quality production and contributes to cost-effective manufacturing.
Due to its availability and the possibility to tailor the bar to customer requirements, this product is well suited for a wide range of applications. Rolling bearings, transmission components, shafts in automotive water pumps, spindles for textile machines, round files, bolts, springs and drills are a few examples of products made out of from Ovako’s drawn bar.
Advantages of Drawn bar
