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
Sharon Steel Corporation the Sharon Steel Hoop Corporation in 1933. Aided by improvement in business conditions, the Sharon Steel continued to expand its sales volume and to make further improvements in production facilities during the thirties. Equipment for the production of terne and tin coating was added, a new product under the trade name of “Galvanite” was produced, and other specialties were added to the company's line of products. New electric furnaces were installed at the Lowellville Works to make stainless steel ingots to be converted into stainless steel strip on the Sharon finishing mills. A great change came about in the company
