This development targets the demand for stainless steel semi-finished products that combine high wear resistance—comparable to cold work tool steels—with outstanding corrosion resistance in aggressive environments, for applications in the food processing industry. Even advanced stainless steels often fail to meet both criteria simultaneously, leading to frequent replacement or compromised performance. The proposed solution is a reinforced stainless steel, designed and manufactured via mechanical alloying, to deliver enhanced durability, processability, and high corrosion stability. Alloy development begins at lab scale by judiciously tuning the incorporation of finely dispersed ceramic reinforcements into an austenitic stainless-steel matrix. The proportions of hard phases are optimized to balance grain refinement, wear resistance, and thermal stability while maintaining sufficient ductility for downstream processing. Selected compositions are consolidated via Hot Isostatic Pressing (HIP) to ensure near-full densification. Post-HIP samples undergo microstructural and mechanical characterization (hardness, wear, corrosion resistance), as well as thermal stability assessments. Heat treatments are applied to tailor hardness, toughness, and microstructural homogeneity. Processability is validated through hot plastic deformation trials, assessing workability limits and final surface finish. The resulting steel demonstrates superior wear and corrosion resistance while remaining compatible with industrial forming operations. Field validation in food processing equipment asses long-term durability, reduced maintenance needs, and enhanced product lifetime. MBN offers full support in customizing alloy composition and processing routes to match specific operating conditions and customer requirements.
