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
Corrugated stainless steel tubing Corrugated stainless steel tubing Corrugated stainless steel tubing (CSST) is tubing made of stainless steel with corrugation on the inside or outside. One type is stainless steel tubing be formed with corrugated shape on outside surface. Make it higher efficiency of heat transfer, can be used to connect the form of tube soft and flexible, with good defensive displacement and vibration and noise reduction, mainly used on heat ex-changers. The other type is a type of conduit used for fuel gas distribution in buildings. It has a flexible corrugated stainless steel inner layer and an outer yellow or black plastic
