Hastelloy se yon non trademark pou yon gwoup alyaj kowozyon ki reziste nikèl ki baze sou.ASTM B622se spesifikasyon estanda a pou tiyo san pwoblèm ak tib ki fèt ak nikèl ak alyaj nikèl-cobalt ki gen ladan Hastelloy. Lè li rive pwopriyete mekanik, ASTM B622 mete kondisyon pou divès aspè tankou fòs rupture, fòs sede, elongasyon, ak dite.
ASTM B622 Hastelloy Pipe Klas
ASTM B622/ASME SB 622se yon spesifikasyon estanda ki kouvri nikèl san pwoblèm ak nikèl-cobalt alyaj tiyo ak tib. Yon total de 32 klas alyaj nikèl enkli nan ASTM B622. Sepandan, gen sèlman 12 klas ki pi souvan itilize nan mitan yo. Gamme pwodwi ASTM B622 se sèlman tiyo san pwoblèm ak tib. Tiyo san pwoblèm yo se yon materyèl tiyo / tib san soude. Li se jeneralman pwodwi pa woule frèt oswa desen frèt. Paske pa gen okenn soude, li gen yon kapasite presyon-pote pi fò pase tiyo soude.

ASTM B622 Hastelloy tiyo Pwopriyete mekanik
Alyaj yo nan ASTM B622 yo se fondamantalman solid solisyon ranfòse alyaj. Paske alyaj sa yo gen eleman ideyal solid solisyon ranfòse tankou molybdène ak tengstèn, fòs yo se pami pi bon nan mitan alyaj solid solisyon ranfòse. Se vre tou ke alyaj sa yo pi difisil pou fabrike tib san pwoblèm. Se poutèt sa, pri yo pral pi chè pase lòt fòm pwodwi.
