Mineral processing components require wear-resistant BÖHLER steels with high strength and toughness. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable, long-lasting performance.
Mineral processing equipment in the mining industry, such as crushers, mills, separators, and conveying systems, operates under extreme conditions involving high abrasion, impact loads, and exposure to corrosive slurries. Material requirements are therefore focused on exceptional wear resistance, high strength, and toughness, as well as resistance to corrosion and erosion caused by aggressive process media. Components must maintain dimensional stability and performance under continuous operation to ensure efficiency and minimize downtime.
BÖHLER high-performance steels and alloys are specifically engineered to meet the demanding conditions of mineral processing. Advanced wear-resistant tool steels, hardened alloy steels, and corrosion-resistant grades provide an optimized balance of hardness, toughness, and resistance to abrasive and chemical attack. Produced using advanced melting technologies, BÖHLER materials ensure superior cleanliness and homogeneous microstructures, reducing crack initiation and improving component life. Key quality features include strict chemical composition control, certified traceability, and precisely controlled heat treatment processes to achieve consistent hardness and wear properties. Comprehensive testing, including abrasion resistance, impact strength, and non-destructive inspection, ensures reliable performance. BÖHLER materials enable robust, efficient, and long-lasting mineral processing operations.
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 K390 MICROCLEAN is a high-alloyed, high-performance cold work tool steel manufactured using powder metallurgy. This material has the highest alloy content in the group of cold work tool steels with high vanadium content. The high alloy content gives this material outstanding wear resistance. At the same time, the powder metallurgical manufacturing process creates a uniform matrix with finely distributed primary carbides. Among other things, this leads to good material toughness. BÖHLER K390 MICROCLEAN is a problem solver for applications requiring extremely high wear resistance and compressive strength.
Read MoreBÖHLER K888 MATRIX – This MATRIX steel offers an excellent combination of high toughness and high compressive strength. MATRIX materials have high toughness, which is a critical factor in many applications. However, the hardness achievable with commonly used MATRIX steels often limits the potential applications. BÖHLER K888 MATRIX breaks through this barrier and offers the best of both worlds of matrix steels and high alloy tool steels. BÖHLER K888 MATRIX is a unique problem solver in situations where high compressive strength and toughness are required. Its advantageous tempering behavior with a pronounced secondary hardness maximum also enables the use of advanced coatings.
