ASTM A269 Nerjaveèi asye tiyo
Nov 23, 2023
ASTM A269 spesifikasyon kouvri san pwoblèm ak soude tiyo asye austenitic pou rezistans jeneral korozyon ak aplikasyon pou tanperati ki ba oswa segondè. Tout materyèl yo dwe apwovizyone nan kondisyon chalè-trete epi konfòme yo ak kondisyon konpozisyon chimik. Espesifikasyon an etabli diferan egzijans tès mekanik, ki gen ladan tès flaring, tès bride, tès dite ak tès ranvèse plat. Anplis de sa, chak tiyo dwe sibi yon tès elektrik ki pa destriktif oswa yon tès idrostatik.
