Ki sa ki estanda ASTM B625?
Spesifikasyon pou UNS N08925, UNS N08031, UNS N08932, UNS N08926, UNS N08354, UNS N08830, ak UNS R20033 Plak, Fèy, ak bann
ASTM B625 se yon spesifikasyon estanda pibliye pa ASTM Entènasyonal ki kouvri plak, fèy, ak teren ki fèt ak plizyè alyaj nikèl. Alyaj sa yo yo itilize nan divès aplikasyon endistriyèl kote rezistans korozyon, fòs segondè-tanperati, ak lòt pwopriyete espesifik yo kritik.
