16NiCrS4 is an case hardening steel with good dimension stability, high toughness and improved machinability.
Ovako 146S is an ingot cast steel. The chemical composition is well controlled to give the steel a controlled hardenability towards the high end (HH). It has reduced silicon content for reduced propensity for internal oxidation during carburizing. Regulated sulphur content ensures good machinability properties.
4730 is an contious cast steel. The chemical composition is well controlled to give the steel a controlled hardenability towards the low end (HL). For improved machinability this steel is processed according to our M-Steel concept.
The concept: Our M-Steel treatment can be applied to any steel grade. The basis for the concept is that non-metallic inclusions are modified and controlled with calcium treatment. These inclusions are modified in a way to maximize machinability.
