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 ...
In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless ...
Inconel 792: Increased aluminum content for improved high temperature corrosion resistant properties, used especially in gas turbines; Inconel 907; Inconel 909; Inconel 925: Inconel 925 is a nonstabilized austenitic stainless steel with low carbon content. [74] Inconel 939: Gamma prime strengthened to increase weldability
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 ...
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, reduction, and desulfurization ...
The US nickel coin contains 0.04 ounces (1.1 g) of nickel, which at the April 2007 price was worth 6.5 cents, along with 3.75 grams of copper worth about 3 cents, with a total metal value of more than 9 cents. Since the face value of a nickel is 5 cents, this made it an attractive target for melting by people wanting to sell the metals at a profit.
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 ...
Stainless steel grade 316L is an austenitic iron-based alloy that features a low carbon content (< 0.03%). Tensile tests and creep tests of 316L steel performed at 600 °C and 650 °C concluded that the SLM steel reached the minimum creep rate at significantly lower creep strains, around one decade lower, compared to the wrought counterpart.
