These prices are more an indication than an actual exchange price. Unlike the prices on an exchange, pricing providers tend to give a weekly or bi-weekly price. For each commodity they quote a range (low and high price) which reflect the buying and selling about 9-fold due to China's transition from light to heavy industry and its focus on ...
American Metal Market (AMM) is an online provider of industry news and metal pricing information for the U.S. steel, nonferrous and scrap markets. Products include a daily publication available electronically, live news on the publication's website, a hard-copy magazine and a series of weekly newsletters covering niche markets.
In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).

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.
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
There are four types of materials available: O-1 tool steel, A-2 tool steel, A-6 tool steel, and 1018 steel (low-carbon or low-carb steel). Lengths are either 18 or 36 in (457 or 914 mm) long, various widths up to 16 in (406 mm) are available, and thicknesses range from 1 ⁄ 64 to 2.875 in (0.40 to 73.03 mm).
That should eventually send prices soaring to $15,000 per ton, he predicted. Coppers prices are already at record highs, with benchmark prices in London at about $10,000 per ton, more than ...
However, too much alumina in the steel will clog the casting nozzles and cause the steel to 'choke off'. Computational fluid dynamics and other fluid flow techniques are being used extensively in the design of new continuous casting operations, especially in the tundish, to ensure that inclusions and turbulence are removed from the hot metal ...
