ASTM A333 tiyo asye kabòn san pwoblèm pou sèvis tanperati ki ba - ak lòt aplikasyon ki gen fòs antay obligatwa
Spesifikasyon sa a kouvri san pwoblèm ak soude kabòn ak alyaj asye tiyo ki fèt pou itilize nan tanperati ki ba. Tiyo a dwe fèt pa pwosesis la san pwoblèm oswa soude ak adisyon a pa gen okenn metal filler nan operasyon an soude. Tout tiyo san pwoblèm ak soude dwe trete pou kontwole mikrostruktur yo. Tès tensile, tès enpak, tès idrostatik, ak tès elektrik nondestructive dwe fèt an akò ak kondisyon espesifye.

TÈS MEKANIK
Tès mekanik yo sou tiyo asye kabòn ki ba -tanperati yo dwe egzekite jan sa a:
transverse/longitudinal tansyon/platiman/dite/pli: tès yo dwe fè sou 5% tiyo ki soti nan chak lot trete. Pou pi piti anpil, omwen yon tiyo dwe teste. Pou chalè materyèl -trete pa pwosesis kontinyèl la, tès yo dwe fèt sou yon kantite ase nan tiyo yo konstitye 5% nan lot la, men nan okenn ka mwens pase 2 tiyo.
Enpak idwostatik/enpak/yon ba kran: dwe fèt ak chak chalè ki reprezante nan yon chaj tretman chalè{0}}sou espesimèn yo pran nan tiyo fini an.
