steel - Treating of steel | Britannica
Cold-formed steel is usually annealed and recrystallized in this manner, holding it for several hours at about 680° C (1,260° F). Annealing is performed in an inert or reducing atmosphere to prevent any oxidation of the steel surface. In batch annealing of cold-rolled strip, for example, several coils are set on a base and on top of one another.Where can I find hot rolled steel coils?In addition to our grades dedicated to the Oil & Gas industry, we deliver steel coils for the manufacture of water or slurry transportation pipes, as well as civil engineering solutions (piling pipes).
