BUFOe: 30% LESS CO2 PER BOLT
Bulten’s green product line BUFOe
By the innovative combination of advanced materials and vast know-how in the cold forging process, we make heat treatment redundant. Reducing energy consumption by >50% and CO2 emissions with >30%.
We use cold forging steel owing its properties to a specifically matched combination of temperature-controlled rolling and the additions of micro- alloying elements. Together with carefully calculated deformation hardening, this allows us to make bolts of strength class 800 to 1000 MPa without quenching and tempering after cold forging.
