Stainless steel, also known as inox, corrosion-resistant steel ( CRES ), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost. Stainless steel's resistance to corrosion results ...
Austenitic stainless steel. Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened [ 1] ). Its primary crystalline structure is austenite ( face-centered cubic) and it prevents steels from being hardenable by heat treatment and makes ...
Definitions. The equilibrium phase diagram of a solid solution of made up of mixtures of α and β. The upper curve is the line of liquidus, and the lower curve is the line of solidus. In chemistry, materials science, and physics, the liquidus temperature specifies the temperature above which a material is completely liquid, [ 2] and the ...
Martensitic stainless steels can be high- or low-carbon steels built around the composition of iron, 12% up to 17% chromium, carbon from 0.10% (Type 410) up to 1.2% (Type 440C): [ 9] Up to about 0.4%C they are used mostly for their mechanical properties in applications such as pumps, valves, and shafts.
Characteristic property. A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Thus, conversely, if the property of a substance changes as the sample size changes, that ...
A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. [4] The general science of metals is called metallurgy , a subtopic of materials science ; aspects of the electronic and thermal properties are also within the scope of condensed matter physics and solid ...
The main differences in composition, when compared with an austenitic stainless steel is that the duplex steels have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen.
Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. At the melting point, the ordering of ions or ...
