Clamping components in mining require BÖHLER steels with high strength, wear resistance, and toughness. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable, long-lasting performance.
Clamping components in the mining industry, such as holders, fixtures, and securing systems for cutting and drilling tools, are exposed to extremely harsh operating conditions including high mechanical loads, impact stress, abrasive wear, and corrosive environments. Material requirements are therefore focused on high strength, exceptional wear resistance, impact toughness, and resistance to deformation under dynamic loading. Stability and durability are critical to ensure reliable tool positioning and minimize downtime in continuous mining operations.
BÖHLER high-performance steels and alloys are specifically engineered to meet these demanding requirements. Advanced quenched and tempered steels, wear-resistant tool steels, and specially alloyed grades provide an optimized balance of hardness and toughness to withstand extreme abrasion and impact. Produced using advanced melting technologies, BÖHLER materials offer superior cleanliness and homogeneous microstructures, reducing the risk of crack initiation and extending service life. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes. Comprehensive testing, including hardness, impact resistance, and non-destructive inspection, ensures consistent performance. BÖHLER materials enable robust, reliable clamping solutions, improving operational efficiency and safety in mining applications.
BÖHLER K110 is a 12% ledeburitic chromium steel and corresponds to material number 1.2379 (X153CrMoV12, D2). This tool steel combines the advantages of conventional 12% ledeburitic chromium steels with those of advanced tool steels. In the group of 12% ledeburitic chromium steels, BÖHLER K110 offers the best combination of wear resistance, compressive strength and toughness, for which reason it is used in virtually all cold work applications. Its advantageous tempering behavior with a pronounced secondary hardness maximum also enables the use of advanced coatings. This also makes BÖHLER K110 suitable for complex tools requiring a high degree of dimensional stability and shape stability.
