TheASTM A992/ A992M -11 (2015) tsanangudzo inotsanangura zvikamu zvesimbi zvakapetwa kuti zvishandiswe muzvivako zvekuvaka, zvivako zvemabhiriji, uye zvimwe zvinowanzoshandiswa. Chiyero chinotsanangudza mareshiyo anoshandiswa kuona makemikari anodiwa ekuongorora kupisa kwemafuta akadai se: kabhoni, manganese, phosphorus, sarufa, vanadium, titanium, nickel, chromium, molybdenum, niobium, uye mhangura. Iyo chiyero zvakare inotsanangura iyo yekumanikidza zvivakwa inodiwa kune tensile yekuyedza maapplication senge goho simba, tensile simba, uye elongation.
ASTM A992(Fy = 50 ksi, Fu = 65 ksi) ndiyo inosarudzirwa chimiro chezvikamu zvakafara zveflange uye zvino inotsivaASTM A36uyeA572Giredhi 50. ASTM A992/A992M -11 (2015) ine mabhenefiti akati wandei: inotsanangudza ductility yemidziyo, inova iyo yakanyanya tensile kuburitsa reshiyo ye0.85; uyezve, pamhando yekabhoni yakaenzana inosvika 0.5 muzana, inotsanangura kuti chidimbu chechinhu chiri 0.85 muzana. , inovandudza weldability yesimbi pane kabhoni yakaenzana tsika kusvika ku0.45 (0.47 yezvinyorwa zvishanu muBoka 4); uye ASTM A992 / A992M -11 (2015) inoshanda kune marudzi ese emhando dzesimbi dzinopisa.
Misiyano pakati peASTM A572 Giredhi 50 zvinhu uye ASTM A992 Giredhi zvinhu
ASTM A572 Giredhi 50 zvinhu zvakafanana neASTM A992 zvinhu asi pane misiyano. Zvikamu zvakafara zveflange zvinoshandiswa nhasi ndezveASTM A992 giredhi. Nepo ASTM A992 uye ASTM A572 Giredhi 50 zvakangofanana, ASTM A992 inokwirisa maererano nekuumbwa kwemakemikari uye kudzora zvivakwa zvemuchina.
ASTM A992 ine hushoma hwegoho rehukoshi hwesimba uye hushoma hwekusimba kwesimba kukosha, pamwe nehukuru hwegoho reshiyo kune tensile simba reshiyo uye yakanyanya kabhoni yakaenzana kukosha. ASTM A992 giredhi haidhure kutenga pane ASTM A572 Giredhi 50 (uye ASTM A36 giredhi) kune yakakura flange zvikamu.
