ASTM A387 Cr-Mo Alloy Steel Presyon Veso Plak

ASTM A387 se yon plak asye kwòm -molybdène alyaj asye ki ka itilize pou trete pwodwi asye, estrikti asye ak pati pwosesis asye. Sa yo plak asye kwòm -molybdène alyaj yo pwensipalman itilize nan chodyèr soude ak veso presyon nan anviwònman tanperati ki wo -.

Plak estanda sa a bay yo enkli ASTM A387 Klas 2, Klas 12, Klas 11, Klas 22, Klas 22L, Klas 21, Klas 21L, Klas 5, Klas 9, Klas 91. Tout klas eksepte Klas 21L, 22L ak 91 yo disponib nan de klas fòs.

Klas 21L ak 22L disponib sèlman kòm Klas 1, alòske Klas 91 la disponib sèlman kòm Klas 2.

Tout plak nou estoke soti nan plizyè nan moulen asye ki pi byen -koni nan Lachin: Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel, Taiyuan Iron and Steel, elatriye.
