ASTM B625 Standard yog dab tsi?
UNS N08925, UNS N08031, UNS N08932, UNS N08926, UNS N08354, UNS N08830, thiab UNS R20033 Phaj, Ntawv, thiab Sawb
ASTM B625 yog ib qho kev qhia tshwj xeeb tshaj tawm los ntawm ASTM International uas npog phaj, ntawv, thiab sawb ua los ntawm ntau cov nickel alloys. Cov alloys no yog siv nyob rau hauv ntau yam kev lag luam daim ntaub ntawv uas corrosion kuj, high-temperature zog, thiab lwm yam khoom tshwj xeeb yog qhov tseem ceeb.
