Cold work tool steel
Arne general purpose oil-hardening tool steel is a versatile manganese-chromium-tungsten steel suitable for a wide variety of cold-work applications.Its main characteristics include:
• Good machinability
• Good dimensional stability in hardening
• A good combination of high surface hardness
and toughness after hardening and tempering.These characteristics combine to give a steel suitable for the manufacture of tooling with good toollife and production economy.Arne can be supplied in various finishes including hot-rolled, pre-machined, fine-machined and precision ground. It is also available in the form of hollow bar.
