and or gas porosity formation takes place which deteriorates corrosion resistance ductility and toughness thus embodiments of the alloys of the present invention limit nitrogen content to about 0 75 to about 1 00 wt while other embodiments are in the range of about 0 75 to about 0 90 wt nitrogen further embodiments incorporate from about 0 78 to about 0 90 wt nitrogen chromium is important in the alloys of the present invention for several reasons for good corrosion resistance high chromium content is needed chromium is the element essential in forming the passive film while other elements can influence the effectiveness of chromium in forming or maintaining the film no other element can by itself create this property of stainless steel for high corrosion resistance values the chromium content of the alloys of the present invention should be at least about 19 0 by weight chromium increases the nitrogen solubility both in the melt and in the solid phase and thereby enables an increased nitrogen content in the alloy high chromium content also contributes to stabilizing the austenite phase against martensite transformation on the other hand because chromium is a ferrite stabilizing element the presence of very high percentages of chromium will lead to.
