Stomatology components require approved biocompatible BÖHLER steels with high corrosion resistance, strength, and surface quality. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable dental performance.
Stomatology applications in medical technology, including dental instruments, implants, orthodontic components, and prosthetic elements, require approved materials that combine high mechanical performance with excellent biocompatibility and corrosion resistance. These components are exposed to cyclic loading, wear, and aggressive oral environments involving saliva, varying pH levels, and cleaning agents. Material requirements therefore focus on high strength, fatigue resistance, wear resistance, and exceptional surface quality to ensure long-term functionality and patient safety. In addition, materials must allow precise machining and polishing to meet strict hygienic and aesthetic standards.
BÖHLER high-performance steels and alloys are specifically designed to meet these demanding requirements. Advanced stainless steels, including austenitic, martensitic, and precipitation-hardened grades, provide an optimal balance of strength, corrosion resistance, and polishability. Using advanced vacuum melting technologies, BÖHLER ensures superior material purity, low inclusion content, and homogeneous microstructures, which are essential for reliable performance and long service life. Key quality features include strict chemical composition control, certified traceability, and validated heat treatment processes. Comprehensive testing, including corrosion resistance, fatigue behavior, and surface integrity verification, ensures compliance with medical standards. BÖHLER materials support durable, safe, and high-precision solutions in modern dental applications.
BÖHLER A220SC is a low carbon, chromium nickel and molybdenum steel. Structure homogeneous, stable austenite. Weldable with analogous filler metal giving fully austenitic deposit. Resistant to intergranular corrosion in the temperature range up to 750°F (400°C). Resistance to acids having a reducing effect, like diluted sulphuric acid and hydrochloric acid is good. The steel is not susceptible to pitting, crevice and stress corrosion cracking in media containing chloride ions and possesses excellent resistance to the attack of urea and biocompatibility. Cold forming properties are good. The steel is capable of taking a mirror finish. The steel is produced as a remelt grade and thus meets the usual requirements for steel purity as specified for implant material.
Read MoreBÖHLER L035 is a 35-cobalt-35-nickel-20-chromium-10-molybdenum wrought alloy (UNS R30035) used for the production of surgical implants. This alloy composition has been successfully used in human implants. Long-term clinical experience has shown an acceptable biological response. The exceptional properties of BÖHLER L035 result from its chemical composition, high-quality melting technology, cold forming and heat treatment. It is a vacuum induction melted (VIM) and vacuum arc remelted (VAR) superalloy. BÖHLER L035 is a nickel-cobalt based multiphase alloy system with a unique combination of properties e.g. extremely high strength, toughness, ductility and excellent corrosion resistance. The alloy can be strengthened and aged in the factory to achieve strength values of max. 260 to 300 ksi (1793-2086 MPa) and stress corrosion cracking (SCC) resistance even in hydrogen sulphide. The BÖHLER L035 alloy resists pitting and crevice corrosion caused by seawater, chloride solutions and other corrosive environments, e.g. mineral acids (nitric, hydrochloric, sulphuric acid).
