20th International Forgemasters Meeting - IFM 2017

3 production companies of Voestalpine Special Steel Division are involved in open die forging business , namly Böhler Edelstahl(Austria), Buderus Edelstahl(Germany) and Villares Metals(Brasil).Equipment, technology and typical products will be described . The transformation process to other product families due to changed global ODF markets will be discussed.

The presentation will highlight the recent developments in the world of Forged Special Steels and remelted steels (nickel alloys, stainless steel, alloy tool steel and alloy steel) as well as will give an overview about end-user demand and structures of these special steels and also summarize the actual status of installations (forging presses and remelting units) on a global scale. The...

Nowadays the production of 9-12% chromium steels is characterized by different metallurgical processes adjusted to the final application and customer requirements. Usually the primary melting is done in the EAF and the steel is further refined in the LF and VD/VOD respectively AOD process. In the production route a special focus lies on the casting and remelting technology. For casting the...

Commercial activity in regions of the world driving the need for large ST and GT generator equipment are showing soft market conditions. These combined with increased competition from equipment OEMs is driving significant pressure on product cost. Techniques such as should cost modeling and partnering with key suppliers and their respective suppliers to drive cost-out initiatives down the...

During the solidification of large ingots, fluid flow and the sedimentation of solid grains can lead to the development of inhomogeneities in chemistry over length scales of a metre or more. This chemical segregation, referred to as macrosegregation, must be understood by manufacturers if they are to produce components that are as homogeneous as possible. This paper explores our current...
