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 the past to 1975, making events happen in and around 34,573 (in the 346th century) – although Professor Coypu also mentions that they are now using a different calendar to the Gregorian calendar. Specifics of the new calendar are never mentioned. "The Stainless Steel Rat", "The Stainless Steel Rat Saves the World" and "The Stainless Steel Rat for President" were adapted into comic strip form in early issues of "2000 AD", written by Kelvin Gosnell and drawn by Carlos Ezquerra. Ezquerra drew Jim with an appearance modelled on the actor James Coburn. They appeared in the following issues of "2000
