ASTM B409 - Strip, Sheet and Plate

ASTM B409 Sheet

ASTM B409 specification covers UNS N08800 form of rolled plate, sheet, and strip. Alloy UNS N08800 is normally employed with service temperatures up to 1100°F (593°C). Alloys UNS N08800 are normally employed in service temperatures above 1100°F (593°C) where resistance to creep and rupture is required, and they are annealed to develop controlled grain size for optimum properties in this temperature range.

Scope And Manufacturing

ASTM B409 specification covers Incoloy 800 Sheet, which is best machined in the annealed condition, with hot-rolled, cold-rolled and hot-forged material giving the best results. It is machined on heavy duty equipment using tools large and heavy enough to withstand the loads and dissipate heat quickly. The primary function of the Hot Strip Mill is to reheat semi finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands, driven by motors totaling 77,000 HP and finally coiling up the lengthened steel sheet to the next process. The Hot Mill rolls slabs weighing up to 30 tons between 30” and 74”. Steel slab 8 to 9 inches thick and up to 36 feet long is rolled into strip as thin as 1/16 inches and up to a half-mile in length. Coils are produced with a 30” inside diameter (‘eye’) on one of two coilers, with outside diameter limitations of 72” and 74”, corresponding to 850 and 1000 pounds-per-inch-width (PIW), respectively.
