Electrical steel is an iron alloy which may have from zero to 6.5% silicon (Si:5Fe). Commercial alloys usually have silicon content up to 3.2% (higher concentrations result in brittleness during cold rolling).
World War I Brodie helmet, made from Hadfield steel. Hadfield was born 28 November 1858 in Attercliffe, then still a village near Sheffield. [1] Hadfield's father, also named Robert Hadfield, owned Hadfield's Steel Foundry in Sheffield and in 1872 was the first manufacturer of steel castings in Britain. He declined to use patented technology ...
The International Standard for the measurement configuration and conditions are defined by the standard IEC 60404-2:2008 Magnetic materials - Part 2: Methods of measurement of the magnetic properties of electrical steel sheet and strip by means of an Epstein frame [1] published by International Electrotechnical Commission.
Worthington Steel is a publicly traded (NYSE:WS) steel processing company headquartered in Columbus, Ohio.Worthington Steel is an independent, intermediate processor of carbon flat-rolled steel in the United States, purchasing steel from integrated steel mills and mini-mills and custom processing it in areas such as type, length, width, thickness, shape and surface quality.

Production facilities have an annual capacity to produce about 200,000 tonnes of electrical steel. In 2006, the company produced 180,000 tonnes of grain-oriented steel and 16,000 tonnes of non-grain-oriented steel. Novolipetsk Steel (NLMK) is the major supplier of hot-rolled coils for further cold rolling at VIZ-Stal. The main customers of ...
An analogous property in electrical engineering and materials science, electric coercivity, is the ability of a ferroelectric material to withstand an external electric field without becoming depolarized. Ferromagnetic materials with high coercivity are called magnetically hard, and are used to make permanent magnets.
A structural drawing, a type of engineering drawing, is a plan or set of plans and details for how a building or other structure will be built.Structural drawings are generally prepared by registered professional engineers, and based on information provided by architectural drawings.
Depending on the proportions of steel scrap, DRI and pig iron used, electric arc furnace steelmaking can result in carbon dioxide emissions as low as 0.6 tons CO 2 per ton of steel produced, [12] which is significantly lower than the conventional production route via blast furnaces and the basic oxygen furnace, which produces 2.9 tons CO2 per ...
