BÖHLER-YBBSTAL PROFIL % waste of cross- section Substitution of Bars with Profiles When does one substitute bars with profiles? high When the machining of the bar accounts for a big loss of the cross-section. Steel grade Keep in mind... low high With high alloyed steel, it is profitable to use a profile even if there is only a small loss on the cross-section. % waste of cross- section BU Group BYP Profiles Profiles vs Bars Special Sections And Shaped Bars Conti - Rolling Line FAB Analysis Applications BYP Strategy © 2005 BY-PROFIL

BÖHLER-YBBSTAL PROFIL These are our strong points . . . Production of profiles which are “made to measure“ to reduce machining costs. Steel grades from unalloyed constructional steels to the highest alloyed steels including nickel-base alloys and titanium. Quotation of customized batches (>500 kg). Tolerances according to DIN resp. ASTM. We can achieve closer tolerances according to special requirements from the customer. BU Group BYP Profiles Profiles vs Bars Special Sections And Shaped Bars Conti - Rolling Line FAB Analysis Applications BYP Strategy © 2005 BY-PROFIL

BÖHLER-YBBSTAL PROFIL These are our strong points . . . Melting process: conventional, ESR, PM and VIM/VAR. Low tooling costs for new profiles. We have the possibility of strain hardening by cold drawing: smaller tolerances brighter surface achievement of specific mechanical properties BU Group BYP Profiles Profiles vs Bars Special Sections And Shaped Bars Conti - Rolling Line FAB Analysis Applications BYP Strategy © 2005 BY-PROFIL

BÖHLER-YBBSTAL PROFIL These are our strong points . . . In applications where high alloyed steels and/or complex shapes are in demand: Heat treatment know-how of the whole steel range. Additional service: sawing (shortlengths), milling, drilling.
