1Structural steel — Various structural steel shapes Structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and mechanical properties. Structural steel shape, size,… …
2steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying …
3État métallurgique — Les propriétés des métaux dépendent de leur composition chimique, mais aussi de leur historique thermomécanique : la déformation plastique les durcit (écrouissage) ; durant le refroidissement, lors de la coulée ou bien lors d un… …
4Microalloyed steel — is a type of alloy steel that contains small amounts of alloying elements (0.05 to 0.15%). Standard alloying elements include: niobium, vanadium, titanium, molybdenum, zirconium, boron, and rare earth metals. They are used to refine the grain… …
5Electrogas welding — (EGW) is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. A shielding gas is sometimes used, but pressure is not applied. A major difference between… …
6molybdenum — /meuh lib deuh neuhm/, n. Chem. a silver white metallic element, used as an alloy with iron in making hard, high speed cutting tools. Symbol: Mo; at. wt.: 95.94; at. no.: 42; sp. gr.: 10.2. [1810 20; < NL, alter. of earlier molybdena < L… …
7Diffusion hardening — Schematic cutaway view of a diffusion hardened metal gear Diffusion hardening is a process used in manufacturing that increases the hardness of steels. In diffusion hardening, diffusion occurs between a steel with a low carbon content and a… …
8A514 — is a particular type of high strength steel, which is quenched and tempered alloy steel, with basic strength of 100,000 psi (100 ksi, where 1 ksi = 1,000 psi) (700 MPa). The trade name T 1 for A514 alloys is extremely common, originally… …
9Katana construction — was the labour intensive bladesmithing process developed in Japan for forging katana and other Japanese blades. Katana and wakizashi were often forged with different profiles, different blade thicknesses, and varying amounts of grind. Wakizashi… …
10Case hardening — or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material s surface, forming a thin layer of a harder alloy. Case hardening is usually done after the part in question …
