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 The Stainless Steel Rat James Bolivar diGriz, alias "Slippery Jim" and "The Stainless Steel Rat", is a fictional character and the antihero of a series of comic science fiction novels written by Harry Harrison. James Bolivar diGriz goes by many aliases, including "Slippery Jim" and "The Stainless Steel Rat". He is a futuristic con man, thief, and all-round rascal. He is charming and quick-witted. He is also a master of disguise and martial arts, an accomplished bank robber, a criminal mastermind, an expert on breaking and entering, and (perhaps most usefully) a skilled liar. Master of self-rationalization, the Rat frequently
