ASSAB

ASSAB is a standard designation system for Swedish tool steels, formulated and promoted by Sweden’s ASSAB Steels. It is widely applied in fields such as mold steel, cold-work steel, hot-work steel, and high-speed steel. This system standardizes the grades, compositions, and properties of tool steels, ensuring that the materials have stable quality and traceability in terms of hardness, toughness, wear resistance, and high-temperature resistance. ASSAB tool steels are renowned for their high purity, excellent processability, and outstanding service life, and are widely used in industries such as mold manufacturing, mechanical processing, automotive, and aerospace.
