ZuS140CrNiMo

This kind of roll material has a high content of nickel-chromium-molybdenum alloy, which has better impact toughness and thermal cracking resistance than ordinary iron rollers, and has high wear resistance of the working layer of the roll body, and has good toughness and strength matching. In particular, the special ductile iron rolls developed for large H-beam and rail beam BD2 rollers are made of pearlite material, and the high-performance rolls with bainite matrix are obtained after high-temperature spray quenching treatment, which successfully replaces the original forged steel rough rolls.
