Yintoni i-ASTM A992?

II-ASTM A992/ A992M -11 Umgangatho ucacisa umyinge osetyenziselwa ukumisela ubume bemichiza efunekayo yemicimbi yohlalutyo enje: I-Carphon, i-genesium, i-titanium, i-titanium, ne-titomium, kunye nobhedu. Owona mgangatho ucacisa iipropathi zoxinzelelo olufunekayo kwizicelo ze-tedsles kwizicelo ezinjengamandla esivumo, amandla enzuzi, kunye ne-elongwation.

I-ASTM A992(FY = 50 ksi, fu = 65 KSI) yiprofayili ekhethiweyo yamacandelo ahlukeneyo eFlanji kwaye ngokuI-ASTM A36kwayeA572Ibanga le-50. I-ASTM A992 / A9A91 (2011 (2015) ineengenelo ezininzi: Icacisa i-genelity yezinto ezibonakalayo, ezibonisa ububanzi be-0.85; Ukongeza, kwi-carbon elilinganayo amaxabiso alinganayo ukuya kuthi ga kwi-0.5 pesenti, ichaza ukuba i-teccity yezinto ze-0.85 pesenti. , iphucula ukuqhekeka kwentsimbi kwi-carbon elilinganayo amaxabiso alinganayo ukuya kuthi ga kwi-0.45 (0.47 (0.47 kwiiprofayili ezintlanu kwiQela 4); kunye ne-ASTM A992 / A992M -11 (2011 (2015) isebenza kuzo zonke iintlobo zeeprofayili ezishushu ezishushu.

Umahluko phakathi kwe-ASTM A572 yeBanga 50 kunye ne-ASTM A992 Ibanga
I-ASTM A572 Ibanga 50 leBanga le-50 lifana ne-ASTM AL992 ngaphandle kwempahla kodwa kukho umahluko. Uninzi lwamacandelo axhaphakileyo asetyenzisiweyo namhlanje yiBanga le-ASTM a992. Ngelixa i-ASTM A992 kunye ne-ASTM A572 IBakala 50 ngokubanzi, i-ASTM A992 iphezulu ngokwemicimbi yobume bekhemikhali kunye nolawulo lwepropathi yolawulo lwepropathi.

I-ASTM A992 inamandla amakhulu esivumo kunye nexabiso lamandla amanye amanxuwa, kunye nenqanaba eliphezulu lokuvelisa amandla omlinganiso we-tensle kunye nexabiso elilinganayo lekhabhoni. I-ASTM A992 Ibakala alibizi kakhulu ukuthenga kune-ATTM A572 iBanga 50 (kunye ne-ASTM A36 yeBanga le-A36) labaxhaphazi.
