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 outfoxed by the mysterious "Special Corps" — a crime-fighting organisation staffed with former criminals — and recruited by them in order to fight crime. Harrison used the story, with minor modifications, as the introduction to the series' first full-length novel, also called "The Stainless Steel Rat". Like other characters created by Harrison, the Rat is a speaker of Esperanto and advocates atheism. There are 13 works in the Stainless Steel Rat series. Based on information in "The Stainless Steel Rat Saves the World" it is possible to work out when the timeline is set: James is sent 32,598 years into
