254 SUMMARY OF CURRENT RESEARCHES RELATING TO 



solidification point practically the same as the eutectic freezing-point for 

 pure iron-carbon alloys, 11;^)()° C. With still further increase of chromium 

 the freezing-point rises, and with 62 p.c. chromium it is 1535° C. A 

 lower critical point at about 710° C. was found in all the alloys contain- 

 ing not more than 21 p.c. chromium. The failure of silicon additions 

 to cause graphite separation demonstrated the powerful influence of 

 chromium in preventing formation of graphite.
