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 Hanasu - a disgraced Kekkonshiki council leader - he persuades them to reinterpret their teachings, and they embark on a more peaceful co-existence with the rest of humanity. (Incidentally "Kekkonshiki" is the romanization of the Japanese word for "Marriage Ceremony" 結婚式.) The MIT class ring, commonly referred to as "The Brass Rat", when cast in Celestrium (also known as jeweler's steel) is often referred to as "The Stainless Steel Rat" in reference to The Stainless Steel Rat series. The Chinese activist Liu Di, writing under the screen name "Stainless Steel Rat" (不锈钢老鼠), became a high-profile symbol for democracy and free
