Grinding operations in food processing require wear- and corrosion-resistant BÖHLER steels with high hardness and hygiene performance. Key quality features include ultra-clean materials, controlled heat treatment, full traceability, and verified surface quality for safe processing.
Grinding operations in food and beverage processing require materials capable of maintaining consistent performance under high wear, mechanical stress, and strict hygienic conditions. Components such as grinder plates, knives, and mills are exposed to abrasion from processed materials, cyclic loading, and frequent cleaning with aggressive agents. Material requirements therefore focus on high hardness, wear resistance, corrosion resistance, and toughness to prevent chipping or premature failure. In addition, excellent surface quality and cleanability are essential to ensure food safety and avoid contamination.
BÖHLER high-performance steels and alloys are specifically engineered for these demanding applications. Advanced martensitic stainless steels and wear-resistant tool steels offer an optimized balance of hardness, edge retention, and corrosion resistance. Produced using advanced melting technologies, BÖHLER materials ensure high purity and homogeneous microstructures, enabling extended service life and reliable operation. Key quality features include precise control of chemical composition, certified traceability, and validated heat treatment processes to achieve consistent hardness and wear properties. Surface integrity and hygienic performance are verified through strict inspection and testing. BÖHLER materials support efficient, safe, and durable grinding operations in modern food processing environments.
BÖHLER K340 ISODUR belongs to the group of 8% chromium steels. This tool steel is produced using the electro-slag remelting (ESR) process developed by BÖHLER. This re-melting technology ensures the lowest micro and macro segregation as well as excellent purity and uniformity of the material. Compared to conventional 12% chromium steels, BÖHLER K340 ISODUR offers significantly better toughness, hardening response and higher resistance to adhesive wear. This material is therefore used in virtually all cold work applications in situations where tool steels like 1.2379 are insufficient in terms of adhesive wear resistance and toughness. K340 ISODUR also features better machinability and reduces the risk of stress cracking during electrical discharge machining.

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.
Read MoreUddeholm Tyrax ESR combines best in class toughness, corrosion and wear resistance. This grade was developed for molding of high performance plastics often filled with glass fiber reinforcements and additives like flame retardants. This matrix- based microstructure is designed to achieve a high-gloss surface by only a few polishing steps, dramatically reducing the tool lead time and enabling production of top quality plastic parts. Uddeholm Tyrax ESR can achieve a high hardness (up to 58 HRC) and is a suitable upgrade from AISI 420 ESR, AISI S7 and AISI 440C. Benefits good dimensional stability at heat treatment and in service even microstructure and small grain size good hardenability Uddeholm Tyrax is also available for Additive Manufacturing, powder for processing Laser Powder Bed Fusion (LPBF) and Laser Metal Deposition (LMD).
