Martensitic stainless steel Martensitic stainless steel Martensitic stainless steel is a specific type of stainless steel alloy. Stainless steels may be classified by their crystalline structure into three main types: "austenitic", "ferritic" and "martensitic". Martensitic stainless steels can be high- or low-carbon steels built around the Type 410 composition of iron, 12% chromium, and up to 1.2% carbon. They are hardenable by heat treatment (specifically by quenching, or by quenching and tempering). The alloy composition, and the high cooling rate of quenching enable the formation of martensite. Tempered martensite gives steel good hardness and high toughness; used largely for medical tools (scalpels, razors
The Stainless Steel Rat Law of Robotics", which featured the Stainless Steel Rat in the setting of Isaac Asimov's "Robot" series. "The Return of the Stainless Steel Rat", a board game inspired by the character, was published by SPI in their magazine "Ares" in the late 1970s. Designed by Greg Costikyan, the game involved the Rat infiltrating a space station under hostile control. Angelina diGriz is a criminal mastermind much like the Rat, only less ethical and more willing to kill. As the Rat's first case for the Special Corps, he tracks Angelina down and ends up falling in love with her. After her
