BÖHLER has revolutionized steel production. Today smelting metallurgy is still our domain, whose innovations are a guide for the technical world. We back up this claim with continuous development work and cutting-edge production systems.
Vacuum smelting and remelting (VIM, VAR) and advanced pressure ESR processes with the highest metallurgical purity are the focal point of the BÖHLER special steel mill. The result: over 200 types of high-speed steels, tool steels, and specialty materials to meet the toughest requirements.
Ever-increasing requirements for tooling are driving demand for new, highly functional materials. The answer is high-performance materials produced using powder metallurgy, with homogenous carbide structure for excellent usage properties – such as our steels. Specialized metallurgical knowledge forms the basis for focused problem-solving and gives our customers a decisive competitive advantage. In order to meet our quality demands over the long term, we have installed the world’s most modern powder-metallurgy production system.
In cutting-edge rolling mills, BÖHLER produce round- and flat-profile bar steel and wire with high precision at high quality. Reproducibility of processes, a high degree of flexibility, and the greatest possible proximity to our customers guarantee our position as a global leader.
Materials are formed to meet our customers’ demands on a 5200 t hammer-forging press or a bar-forging machine.

Before supplying our products, every material is treated accordingly to its specified heat treatment necessities, always focusing on the right values that will guarantee its best qualities. An important step in our production process consists on machining the forging products.
An important step in our production process consists on machining the forging products. Most of these products will be used in power generation, oil & gas / CPI and for turbines and compressors.
Thanks to a wide range of potential finishing processes for bar products, individual requirements can be covered quickly with the quality that BÖHLER is known for. The rolled bar steel is subjected to quality heat treatment according to the customer’s specification and then adjusted, processed, and inspected. We can fulfill any wish for the surface finish as well: peeled, polished, belt-ground, turned, milled, or sawn, in the tolerance class of your choice.
