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 K340 ISODUR belongs to the group of 8% chromium steels. This tool steel is produced using the electro-slag remelting (ESR) process developed by BÖHLER. This re-melting technology ensures the lowest micro and macro segregation as well as excellent purity and uniformity of the material. Compared to conventional 12% chromium steels, BÖHLER K340 ISODUR offers significantly better toughness, hardening response and higher resistance to adhesive wear. This material is therefore used in virtually all cold work applications in situations where tool steels like 1.2379 are insufficient in terms of adhesive wear resistance and toughness. K340 ISODUR also features better machinability and reduces the risk of stress cracking during electrical discharge machining.
