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 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
