A UNS number only defines a specific chemical composition, it does not provided full material specification. Requirements such as material properties (yield strength, ultimate strength, hardness, etc.), heat treatment, form (rolled, cast, forged, flanges, tubes, bars, etc.), purpose (high temperature, boilers and pressure vessels, etc.) and testing methods are all specified in the material or ...
C95400 defines an alloy, a range of material compositions, which Ampco 18 meets. So Ampco 18 is an example of a C95400 alloy which nominally meets the properties of Ampco 18. (Without guarantees, since Ampco only offers nominal properties.)--Yannick 00:46, 30 October 2007 (UTC) I see a logical flaw in the statement "UNS C95400 is Ampco 18".
AMPCO METAL is a diversified speciality alloy engineering company working primarily in copper based alloys, non-sparking safety tools and speciality welding products. The Switzerland based company is a manufacturer of engineered alloys of different compositions and properties, intended for specific uses in the aerospace, automotive, energy conservation, manufacturing and other industries.
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
Ampco-Pittsburgh Corporation (American Metal Products Company) is a specialty steel manufacturer headquartered in Downtown Pittsburgh, Pennsylvania. [3] It is one of several companies to bear the Ampco name, and it should not be confused with the Milwaukee-based copper base alloy producer, Ampco Metal Inc.; the Miami-based cabinetry company; the Swiss aluminum corporation; or the Dallas-based ...
