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 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
