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 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.
Citește mai multBÖHLER K700 corresponds to the material 1.3401 (X120Mn12) and belongs to the group of austenitic hard manganese steels. Unlike most tool steels, BÖHLER K700 is not used in the hardened and tempered condition. Due to the forces occurring in service, the resulting work hardening of the surface results in a high resistance to abrasive wear. BÖHLER K700 is weldable. However, the heat input must be kept as low as possible to avoid embrittlement of the material. The material is used in abrasive blasting and mining applications such as crusher jaws, beater bars, grate bars, linings, excavator teeth and chain rollers.
