Abstract : 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)
