Process of producing nitrogen rich wrought austenitic alloys

Claim 1

TH EPROCESS OF PRODUCING A SOUND, IRON BASE, STABLY AUSTENIC ALLOY CONTAINING AS NECESSARY ELEMENTS FROM TEN TO THIRTY PERCENT OF CHRONIUM, FIVE TO TWENTY PERCENT OF MANGANESE AND FROM THREE TENTHS TO ONE PERCENT OF NITROGEN AND IN WHICH THE AUSENTENITIZING ELEMENTS AND THE FERRITE FORMING ELEMENTS ARE PROPORTIONED TO PERMIT A STABLY AUSTENTIC ALLOY AT THE DESIRED NITROGEN LEVEL COMPRISING PRODUCING A MELT OF THE DESIRED COMPOSITION, CASTING THE MELT INTO AN INGOT MOLD, PERMITTING A SOLID SKIN TO FORM ON TH INGOT WITH THE SIMULTANEOUS EBULLITION OF NITROGEN, CAPPING THE INGOT TO ENTRAP A SUBSTANTIAL AMOUNT OF NITROGEN IN THE GASEOUS FORM AS BUBBLES, PERMITTING THE INGOT TO COMPLETELY SOLIDIFY AND SUBJECTING THE INGOT TO INTENSIVE HOT WORKING WHEREBY THE GASEOUS NITROGEN CONTAINED IN THE INGOT IS REDISSOLVED AND THE SIDES OF THE NITROGEN CAVITIES WELDED SHUT TO PRODUCE A SOUND AND MECHANICALLY STRONG METAL.
