Title: Process for reducing the nitrogen content of steels
IPC: C21D3/08
Filed: 1952-05-09
Abstract: The nitrogen content of steels containing at most 1 per cent of carbon is reduced by heating the steel in the solid state to a temperature above 1350 DEG C.  The steel may be maintained at a temperature just below that of solidification immediately after casting or may be heated to such a temperature.  The duration of heating depends on the thickness of the metal and may vary between 10 minutes and 2 hours.  A protective atmosphere, e.g. coal gas, hydrogen, or nitrogen, containing no more than 1 per cent of oxygen may be used to prevent oxidation during heating. If steel which forms a delta phase is used the treatment should take place at the temperature at which the delta phase is present.
