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 name is not revealed to the reader. The Kekkonshiki, also known as "The Gray Men", are a human culture who initially prefer domination to coexistence. Their expertise lies in using technology to manipulate sentient minds, and they have manipulated both humans and aliens on a grand scale. Jim has experienced one of their techniques (in which a gray man agent seemingly severs his hands with an axe; this was an illusion). Jim has knowingly opposed them on two separate occasions ("The Stainless Steel Rat's Revenge" & "The Stainless Steel Rat Wants You") however during conversation it is revealed by Kome
