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 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 them essentially non ...
904L is an austenitic stainless steel. It is harder than 316L, [ 1] and its molybdenum addition gives it superior resistance to localized attack ( pitting and crevice corrosion) by chlorides and greater resistance reducing acids; in particular, its copper addition gives it useful corrosion resistance to all concentrations of sulfuric acid.
Superalloy. A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [ 1] Key characteristics of a superalloy include mechanical strength, thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance. The crystal structure is typically face ...
Ferritic stainless steel[ 2][ 3] forms one of the five stainless steel families, the other four being austenitic, martensitic, duplex stainless steels, and precipitation hardened. [ 4] For example, many of AISI 400-series of stainless steels are ferritic steels. By comparison with austenitic types, these are less hardenable by cold working ...
Vacuum arc remelting ( VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. [ 1] The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible tightly-controlled materials used in biomedical ...
Argon oxygen decarburization. Argonoxygen decarburization ( AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminium. After initial melting the metal is then transferred to an AOD vessel where it will be subjected to three steps of refining; decarburization ...
Worker and Kolkhoz Woman (Russian: Рабочий и колхозница, romanized: Rabochiy i kolkhoznitsa) is a sculpture of two figures with a sickle and a hammer raised over their heads. The concept and compositional design belong to the architect Boris Iofan. It is 24.5 metres (78 feet) high, made from stainless steel by Vera Mukhina for ...
