Silicon contents to about 3 increase the resistance to carburization of Type 321 and Type 347 stabilized stainless steels. Tests were conducted at 1700F 925C, 1800F 980C, and 1900F 1040C in a mixture of methane-hydrogen. Silicon additions to Type 321 steel are more effective in reducing carburization than additions to Type 347. Under the conditions used, a 3 silicon concentration in Type 321 makes the alloy completely resistant to carburization for 1 hr at 1700F 925C and 1800F 980C. The mechanical properties and joining characteristics welding and brazing were also studied. Author
