§A36 steel is a standard steel alloy that is a common structural steel in the United States.〔''Steel Construction Manual'', 8th Edition, second revised edition, American Institute of Steel Construction, 1986, ch. 1 pages 1–5.〕 The A36 standard was established by the standards organization ASTM International. == Properties == As with most steels, A36 has a density of . Young's modulus for A36 steel is .〔(【引用サイトリンク】 url=http://www.matweb.com/search/DataSheet.aspx?MatGUID=d1844977c5c8440cb9a3a967f8909c3a&ckck=1 )〕 A36 steel has a Poisson's ratio of 0.26, and a shear modulus of . A36 steel in plates, bars, and shapes with a thickness of less than has a minimum yield strength of and ultimate tensile strength of . Plates thicker than 8 in have a yield strength and the same ultimate tensile strength.〔 The Electrical Resistance of A36 is 0.0000153 ohm/cm. A36 bars and shapes maintain their ultimate strength up to 650°F. Afterward, the minimum strength drops off from 58,000 psi: 54,000 psi at 700°F; 45,000 psi at 750°F; 37,000 psi at 800°F. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A36 steel」の詳細全文を読む スポンサード リンク
