Effect of vacuum casting on quality of heavy forgings
Vacuum casting of 34KhN3M steel reduced hydrogen content by 40% as compared with conventional casting; this completely eliminates formation of flakes and reduces amount of nonmetallic inclusions; isothermal holding of forgings of basic vacuum treated steel for 6 hr/100 mm of section is not sufficient to avoid appearance of flakes. (See also Stal v 21 n 7 July 1961 p 642-5)
