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 name is not revealed to the reader. The Kekkonshiki, also known as "The Gray Men", are a human culture who initially prefer domination to coexistence. Their expertise lies in using technology to manipulate sentient minds, and they have manipulated both humans and aliens on a grand scale. Jim has experienced one of their techniques (in which a gray man agent seemingly severs his hands with an axe; this was an illusion). Jim has knowingly opposed them on two separate occasions ("The Stainless Steel Rat's Revenge" & "The Stainless Steel Rat Wants You") however during conversation it is revealed by Kome
