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 ...
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
To qualify as stainless steel, Fe-base alloys must contain at least 10.5% Cr. The iron-chromium phase diagram shows that up to about 13% Cr, the steel undergoes successive transformations upon cooling from the liquid phase from ferritic α phase to austenitic γ phase and back to α.
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): [8] The chromium and carbon contents are balanced to have a martensitic structure.
The US Army's flat ovoid M-1932 wartime-issue mess kit was made of galvanized steel (stainless steel in the later M-1942), and was a divided pan-and-body system. When opened, the mess kit consisted of two halves: the deeper half forms a shallow, flat-bottom, ovoid "Meat can, body", designed to receive the "meat ration", the meat portion of the ...
A steel framing system was devised consisting of vertical steel studs and roof-ceiling trusses to which all interior and exterior panels were attached. The concept of prefabricated housing was well established by firms such as The Aladdin Company , Gordon-Van Tine Company , Montgomery Ward , and Sears in the early 1900s.
