Drilling components in mining require BÖHLER steels with high toughness, strength, and wear resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable, long-lasting performance.
Drilling components in the mining industry, such as drill rods, bits, and tool holders, are exposed to extreme operating conditions including high impact loads, abrasive wear, and cyclic stresses in aggressive environments. Material requirements are therefore focused on exceptional toughness, high strength, superior wear resistance, and resistance to fatigue and crack propagation. In addition, resistance to corrosion and stability under varying temperatures are critical to ensure consistent drilling performance and extended service life in demanding underground and surface mining operations.
BÖHLER high-performance steels and alloys are specifically engineered to meet these rigorous requirements. Advanced quenched and tempered steels, wear-resistant tool steels, and specially alloyed grades provide an optimal combination of hardness and toughness for maximum durability and reliability. Produced using advanced melting technologies, BÖHLER materials offer superior cleanliness and homogeneous microstructures, minimizing the risk of failure under extreme stress. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes tailored to application needs. Comprehensive testing, including impact strength, wear resistance, and non-destructive inspection, ensures consistent performance. BÖHLER materials enable efficient, reliable, and cost-effective drilling operations in the mining industry.
BÖHLER K455 corresponds approximately to the material 1.2550 (~60WCrV7, ~S1) in terms of the alloy concept. This classic matrix steel is characterized by high toughness, good machinability and polishability. BÖHLER K455 offers the advantage of simple heat treatment with low hardening temperatures and single tempering. BÖHLER K455 is widely used in the field of punching and cutting tools as well as in the field of embossing tools.
Citește mai multBÖHLER K600 corresponds to the material 1.2767 (45NiCrMo16). With its high nickel content, this material offers a very good combination of through hardenability and toughness. This results in a high resistance to impact and shock loads. BÖHLER K600 is used for a wide range of tools where high toughness is required. The material is used for forming and bending tools, cold shear blades for thick materials and for reinforcement rings. Due to its good polishability, BÖHLER K600 is also used for embossing tools, plastic molds and mold inserts for injection molding.
