单词 stainless steel
释义
stainless steel

Physics
  • A form of steel containing at least 11–12% of chromium, a low percentage of carbon, and often some other elements, notably nickel and molybdenum. Stainless steel does not rust or stain and therefore has a wide variety of uses in industrial, chemical, and domestic environments. A particularly successful alloy is the steel known as 18–8, which contains 18% Cr, 8% Ni, and 0.08% C.

Chemical Engineering
  • Alloys of iron noted for their resistance to corrosion and containing small amounts of carbon as well as chromium. Most stainless steels also contain nickel. Various other metals and non-metals are also often added to provide particular properties. They are resistant to corrosion due to a thin protective oxide coating on the surface. An example is 18:8:1 stainless steel which contains 18 per cent nickel, 8 per cent chromium, and 0.01 per cent carbon. Being of a high tensile strength and with excellent corrosion resistance, stainless steels are used extensively in the chemical and process industries for pipework and vessels.
