IyoASTM A992/A992M -11 (2015) tsanangudzo inotsanangura zvikamu zvesimbi zvakakungurutswa zvinoshandiswa muzvivakwa zvekuvaka, zvivakwa zvebhiriji, nezvimwe zvivakwa zvinowanzoshandiswa. Muyero unotsanangura zviyero zvinoshandiswa kuona kuumbwa kwemakemikari anodiwa pakuongorora kupisa zvakaita se: kabhoni, manganese, phosphorus, sarufa, vanadium, titanium, nickel, chromium, molybdenum, niobium, uye mhangura. Muyero unotsanangurawo hunhu hwekumanikidza hunodiwa pakushandiswa kwekuyedza tensile senge simba rekukura, simba re tensile, uye kureba.
ASTM A992(Fy = 50 ksi, Fu = 65 ksi) ndiyo inonyanya kusarudzwa pamhando yezvikamu zveflange yakafara uye ikozvino inotsivaASTM A36uyeA572Giredhi 50. ASTM A992/A992M -11 (2015) ine zvakanakira zvakasiyana: inotsanangura ductility yechinhu ichi, inova chiyero chepamusoro chekudhonza kusvika pakukohwa che0.85; pamusoro pezvo, pa carbon equivalent values kusvika ku0.5 muzana, inotsanangura kuti ductility yechinhu ichi i0.85 muzana. , inovandudza weldability yesimbi pa carbon equivalent values kusvika ku0.45 (0.47 yema profiles mashanu muGroup 4); uye ASTM A992/A992M -11(2015) inoshanda kune ese marudzi e hot-rolled steel profiles.
Musiyano uripo pakati pezvinhu zveASTM A572 Giredhi 50 nezvinhu zveASTM A992 Giredhi
Zvinhu zveASTM A572 Grade 50 zvakafanana nezvinhu zveASTM A992 asi pane musiyano. Zvikamu zveflange zvakafara zvinoshandiswa nhasi ndezveASTM A992 grade. Kunyange zvazvo ASTM A992 neASTM A572 Grade 50 zvinowanzofanana, ASTM A992 iri nani pane zvemakemikari uye kutonga kwemidziyo.
ASTM A992 ine simba rekuyedza zvishoma uye simba rekuyedza zvishoma, pamwe nechiyero chesimba rekuyedza zvakanyanya kusvika pakuyedza uye kukosha kwakakwira kwekabhoni kwakaenzana. Giredhi reASTM A992 haridhuri kutenga kupfuura ASTM A572 Giredhi 50 (uye giredhi reASTM A36) yezvikamu zveflange zvakafara.
