Stainless steel as the common ferritic and austenitic stainless steels due to their low chromium content. Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. They are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels. Their mixed microstructure provides improved resistance to chloride stress corrosion cracking in comparison to austenitic stainless steels Types 304 and 316. The properties of
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
