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 A903 (UNS S32205) is the most common stainless ferritic-austenitic Cr-Ni-Mo steel with nitrogen addition. In addition to good strength properties, this steel offers high corrosion resistance, especially against stress corrosion cracking in chloride-containing solutions, and is resistant to intergranular corrosion up to 300°C. The alloy should not be used at temperatures above 300°C due to embrittlement. Heat treatment after welding is not necessary. Required surface finish: pickled, scale-free heat treated or machined. Commonly used in the oil and gas industry, hydroelectric power, pressure vessels, pulp and paper industry, components and chemical tanks, such as parts for separators and heat exchangers and parts in the paper industry, oil and gas extraction , compressors, seawater desalination.

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 MoreBÖHLERL718 API (UNS N07718) is a high-strength, corrosion-resistant nickel-chromium-iron-molybdenum material with excellent corrosion resistance, especially in H2S and CO2 environments. The alloy is age-hardenable due to the addition of niobium, titanium and aluminium. BÖHLER L718 API is recognised by the oil industry for its simple and cost-effective production in combination with good tensile, fatigue, creep and fracture strength and is used in a wide range of applications in this sector. BÖHLER L718 API has excellent weldability and is resistant to cracking after welding. The material can be used at high temperatures. BÖHLER L718 API is available in the NACE/API 6A CRA versions with a minimum yield strength of 120/140 ksi and also in the high-strength version with 150 ksi. All hardness grades are suitable for sour service and can be used for pressurising and pressure-controlling equipment in corrosive environments. Typical applications include packers, pumps, connectors and fasteners as well as gate valves, throttle spindles, pipework hangers and fire safe valves, but also a wide range of downhole and completion components, nuclear and surface applications.
