4Cr2NiMoV Hot Work Mold Steel

Grade 4Cr2NiMoV is a Chinese tool and mould steel. It is a kind of hot work mold steel under GB/T 1299-2014 standard. The containing molybdenum element makes 4Cr2NiMoV hot work mold steel has excellent toughness and high hardenability. 4Cr2NiMoV mold steels are frequently used in hot work applications requiring toughness are relatively high hardness levels.
