Abstract

The invention relates to a method for method for solution hardening of a cold deformed workpiece of a passive alloy containing at least 10% chromium which method comprises- dissolving at least nitrogen in the workpiece at a temperature T1, which is higher than the solubility temperature for carbide and/or nitride and lower than the melting point of the passive alloy wherein dissolution of nitrogen at temperature T1 is performed to obtain a diffusion depth in the range of 0 µm to 5 mm, and - cooling the workpiece after the dissolution step at temperature T1 to a temperature which is lower than the temperature at which carbides and/or nitrides form in the passive alloy, wherein the cooling step takes place in an inert gas not containing nitrogen. The invention further relates to a member ,such as a lock washer for securing bolts or nuts prepared using the method.
