Extrusion components in food processing require wear- and corrosion-resistant BÖHLER steels with high strength and hygiene performance. Key quality features include ultra-clean materials, controlled heat treatment, full traceability, and optimized surfaces for reliable processing.
Extrusion operations in food and beverage processing place high demands on materials due to continuous mechanical loading, elevated temperatures, pressure, and exposure to aggressive cleaning media. Components such as screws, barrels, and dies must ensure consistent product quality while maintaining strict hygiene standards. Material requirements focus on high wear and abrasion resistance, corrosion resistance, and dimensional stability under thermal and mechanical stress. Additionally, resistance to adhesive wear and surface degradation is critical to prevent contamination and ensure consistent processing performance.
BÖHLER high-performance steels and alloys are specifically developed to meet these challenges. Advanced tool steels and corrosion-resistant stainless steels offer an optimized balance of hardness, toughness, and resistance to wear and chemical attack. Produced using advanced melting technologies, BÖHLER materials ensure high purity and homogeneous microstructures, supporting long service life and stable processing conditions. Key quality features include precise chemical composition control, certified traceability, and validated heat treatment processes to achieve tailored hardness and surface properties. Surface finish and integrity are strictly controlled to meet hygiene requirements. Comprehensive testing ensures compliance with food safety standards. BÖHLER materials enable efficient, reliable, and hygienic extrusion processes with extended tool lifetime.
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 K890 MICROCLEAN is a high-performance cold work tool steel manufactured using powder metallurgy. It features good toughness, very high compressive strength and excellent fatigue strength. This favorable combination of properties can avoid chipping damages to tools. BÖHLER K890 MICROCLEAN is not only used in cold work applications, but also in mold making.
Read MoreBÖHLER M390 MICROCLEAN is a corrosion-resistant, martensitic chromium steel produced by powder metallurgy. Due to its alloy design, this steel has very high wear resistance and good corrosion resistance. In addition, BÖHLER M390 MICROCLEAN is approved for food and beverage contact.
Read MoreUddeholm Sleipner is a general purpose steel for cold work tooling. It has a mixed-abrasive wear profile and a good resistance to chipping. Furthermore a high hardness (>60 HRC) can be obtained after high temperature tempering. This means that surface treatments such as nitriding or PVD can be made on a high strength substrate. Also, it means that complicated shapes with hardness levels >60 HRC can be wire EDM’d from blocks with relatively thick cross-sections with a much reduced risk of cracking. Uddeholm Sleipner is recommended for medium run tooling applications where a resistance to mixed or abrasive wear and a good resistance to chipping are required. Benefits Very broad property profile Very good steel for all types of surface treatments Extremely versatile conventional tool steel for medium run cold work tooling Suitable upgrade where added chipping or wear resistance is needed over traditional AISI A2 or AISI D2 In East/South East Asian countries served by ASSAB, Uddeholm Sleipner is sold as ASSAB 88.
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).
