![]() ![]() Automotive applications are common final destinations for ferritic alloys because of their chromium-induced strength and sheen. Ferritic alloys: These are less-expensive steels with low amounts of carbon and nickel.They’re formed by a rapid-cooling process that makes them ideal for heat treatment and are found in medical instruments, cutlery and pliers. Martensitic alloys: Toughness is a hallmark of martensitic alloys, but they’re prone to corrosion.It’s is grouped into four subcategories that each serve a different purpose. Kitchen, medical and automotive applications are common, but stainless steel is highly valued for other uses as well. The sheen in high-chromium stainless steel applications is less mirror-like due to the addition of other elements. Stainless steel is different from chrome when chromium is electroplated onto another metal to produce a tough, polished coating. Higher chromium content directly translates to a higher gloss when polished and has greater resistance to corrosion. Typically, stainless steel has a chromium content of more than 10.5% and sometimes contains up to 30% in certain applications. ![]() Chromium is the alloy that sets stainless steel apart, lending the material its distinctive luster.Ĭhromium is more than a purely cosmetic addition, however: the element is oxidation-resistant and will increase the metal’s longevity by preventing it from rusting. This type is commonly known for its role in manufacturing medical equipment and appliances, but its range of use is far greater than just the gas range in your kitchen. They do not contain more than 2% carbon.Ĭarbon steel’s relative adaptability and low cost make it an ideal choice for a variety of construction projects, both large and small-scale. High carbon: The toughest variety is more than 0.61% carbon and is often used to produce brick nails and sharp cutting tools like trencher blades.Medium carbons are found in gears and railroad tracks. ![]()
