Stainless steel are magnetic like carbon steel. They are problematic to weld due to grain growth in the heat affected zone which reduces ductility and may result in cracks. Increasing chromium and molybdenum contents increase corrosion resistance as it does for austenitic stainless steels, however, this high alloying results in the precipitation of embrittling intermetallic phase upon welding. These microstructural problems due to welding restrict the use of ferritic stainless steels to very thin thicknesses and thus are not used in the construction of large heavy walled vessels and tanks, and structures like austenitic stainless steels. Common ferritic grades are: Type AISI
The Stainless Steel Rat that prior to "The Stainless Steel Rat Wants You" Jim has in fact thwarted their plans twice already, making this their third encounter. The text can also be read to say that the second time he thwarted their plans was with the alien invasion so the third encounter also happened during "The Stainless Steel Rat Wants You" when Jim invaded their home planet. They live on a harsh, icy world; this existence forced them to eliminate all emotion from their culture. This society is also completely patriarchal, with women being treated as nothing more than property. During Jim's interactions with
