Product Details

ASTM 4140/JIS SUS SCM440 /DIN 42CrMo4

This steel is ultra high strength steel, high strength and toughness, hardenability is also good, no obvious temper brittleness, quenching and tempering treatment after the fatigue limit and the high resistance to repeated shocks, good low temperature impact toughness. The steel is suitable for large, medium-sized plastic mold manufacturing requires a certain strength and toughness.
