Mining pumps require BÖHLER steels and alloys with outstanding wear, corrosion, and fatigue resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable, long-lasting performance.
Pumping systems in the mining industry are exposed to some of the most demanding operating conditions, including abrasive slurries, highly concentrated mineral particles, corrosive process fluids, and continuous mechanical loading. Components such as pump shafts, impellers, casings, wear rings, and sealing elements must withstand severe erosion, abrasion, and fatigue while maintaining operational reliability and efficiency. Material requirements therefore focus on exceptional wear resistance, high strength, impact toughness, corrosion resistance, and dimensional stability under demanding service conditions. Long service life and reduced maintenance requirements are critical to maximizing productivity and minimizing downtime.
BÖHLER high-performance steels and alloys are specifically engineered to meet these mining challenges. Advanced wear-resistant alloy steels, martensitic and stainless steel grades, as well as specially developed corrosion-resistant materials, provide an optimized balance of hardness, toughness, and durability. Produced using advanced melting and refining technologies, BÖHLER materials offer superior cleanliness, low inclusion levels, and homogeneous microstructures, significantly improving resistance to wear, fatigue, and crack propagation. Key quality features include strict chemical composition control, certified material traceability, and precisely controlled heat treatment processes. Comprehensive testing, including abrasion resistance, corrosion performance, mechanical verification, and non-destructive inspection, ensures consistent quality. BÖHLER materials enable reliable, durable, and cost-efficient pumping solutions for demanding 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.
Read MoreBÖHLER 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.
