ASTM A335 Tiyo alyaj pou Tanperati segondè
Nov 05, 2025
A335/A335M spesifikasyon kouvri feritik alyaj tiyo asye san pwoblèm ki gen entansyon pou sèvis tanperati ki wo -, ki gen ladan epesè miray nominal ak epesè miray minimòm. Tiyo yo te bay lòd nan spesifikasyon sa a dwe apwopriye pou koube, flaring (soude gaz), ak operasyon menm jan fòme, osi byen ke soude fizyon. Seleksyon an dwe baze sou konsepsyon, kondisyon sèvis, pwopriyete mekanik, ak karakteristik tanperati ki wo -.
