Abstract (en)

[origin: WO0117767A2] The invention relates to a method for producing heat and corrosion-resistant austenitic steel, nickel alloys and cobalt alloys. Said method enables the production of austenitic materials with a significantly higher aluminium content in the border area, in comparison to those in prior art and thus with both a significantly greater heat-resistance and a significantly greater abrasion-resistance.
