Bismarck Municipal Airport [2] [3] (IATA: BIS [4], ICAO: KBIS, FAA LID: BIS) is in Burleigh County, North Dakota, United States, [2] three miles southeast of the City of Bismarck, North Dakota, which owns it. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a primary commercial service airport. [5]
Sioux Falls Regional Airport (IATA: FSD, ICAO: KFSD, FAA LID: FSD), [3] also known as Joe Foss Field, [2] is a public and military use airport three miles northwest of Sioux Falls, South Dakota, United States. [2] It is named in honor of aviator and Sioux Falls native Joe Foss, who later served as the 20th Governor of South Dakota (1955–1959).
On certified steels, the plates are marked with the grade and a preceding "AB/", e.g. AB/A etc. [3] Yield point for all ordinary-strength ABS steels is specified as 34,000 psi (235 MPa ), except for ABS A in thicknesses of greater than 1 inch (25 mm) which has yield strength of 32,000 psi (225 MPa), and cold flange rolled sections, which have ...

The older United States Standard Gauge is based upon 40 lb per square foot per inch thick. Gauge is defined differently for ferrous (iron-based) and non-ferrous metals (e.g. aluminium and brass). The gauge thicknesses shown in column 2 (U.S. standard sheet and plate iron and steel decimal inch (mm)) seem somewhat arbitrary.
ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the US for hollow structural sections, but the more stringent CSA G40.21 is preferred in Canada.
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).
At 700 °F, the design yield stress ratio is about 71% of room temperature stress. Temperatures above 800 °F may cause mild carbon steel to warp. This is because, in this temperature range, the crystal lattice structure of mild carbon steel changes with temperatures above about 800 degrees F (reference, US Steel Plate, elevated temperature steel).
