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 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
