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
Braided stainless steel brake lines additional rubber outer sheath, braided stainless steel hoses typically consist of a Teflon® or generic PTFE (polytetrafluoroethylene) inner hose wrapped in a braid consisting of stainless steel wire. The stainless wire braid more effectively resists expansion due to pressure inside the hose core. This improves brake system effectiveness by more directly transferring operator input (hydraulic pressure) to brake friction surfaces. While available without a coating, the stainless braid is typically coated or covered with a clear or colored material such as PVC (polyvinyl chloride) to protect the wire and inner hose from the elements and chemicals, to protect the vehicle
