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.
Mill scale on an anvil. Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO, wüstite), iron(III) oxide (Fe 2 O 3, hematite), and iron(II,III) oxide (Fe 3 O 4, magnetite).
A coil of hot-rolled steel Hot-rolled metals generally have little directionality in their mechanical properties or deformation-induced residual stresses . However, in certain instances non-metallic inclusions will impart some directionality and workpieces less than 20 mm (0.79 in) thick often have some directional properties.
As more steel is produced than is scrapped, the amount of recycled raw materials is about 40% of the total of steel produced – in 2016, 1,628,000,000 tonnes (1.602 × 10 9 long tons; 1.795 × 10 9 short tons) of crude steel was produced globally, with 630,000,000 tonnes (620,000,000 long tons; 690,000,000 short tons) recycled.
EN 10025 - Hot rolled products of structural steels refers to a set of European standards which specify the technical delivery conditions for hot rolled products of structural steels.
The industry argued that steel tariffs imposed in 2018 boosted steel prices, profits, and employment. They have also publicly called for stricter enforcement of trade laws and increased tariffs on steel-intensive products from China and Southeast Asia. [21]
ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.
The term long products may include hot rolled bar, cold rolled or drawn bar, rebar, railway rails, wire, rope (stranded wire), woven cloth of steel wire, shapes (sections) such as U, I, or H sections, and may also include ingots from continuous casting, including blooms and billets. Fabricated structural units, such bridge sections are also ...
