Txhua Yam Koj Yuav Tsum Paub Txog Astm B575 Standard

Taw qhia rau ASTM B575 Txuj:

ASTM B575 yog ib qho kev qhia tshwj xeeb uas tsim los ntawm American Society for Testing and Materials (ASTM) uas qhia txog cov kev cai rau nickel-molybdenum-chromium-hlau alloys (UNS N10276, N06022, N10665, thiab N10675) phaj, ntawv, thiab sawb.

Cov khoom hauv qab no tau them raws li qhov specification no:

Daim ntawv thiab Sawb-Kub los yog txias dov, tov annealed, thiab descaled tshwj tsis yog tias cov tshuaj anneal ua nyob rau hauv ib qho chaw yielding ib tug kaj tiav.
Phaj-kub los yog txias dov, tov annealed, thiab descaled.

Xws li Qib thiab Tshuaj Chemical Composition:

ASTM B575 npog plaub qib ntawm npib tsib xee-molybdenum-chromium-hlau alloys, txhua tus muaj nws cov tshuaj muaj pes tsawg leeg:
1. UNS N10276 (Hastelloy C-276, 2.4819): Muaj nickel, molybdenum, chromium, thiab hlau, nrog ntxiv ntawm tungsten thiab cobalt.
2. UNS N06022 (ib.Hastelloy C-22, 2.4602): Muaj cov nickel, chromium, molybdenum, thiab tungsten, nrog tswj qib ntawm hlau thiab cobalt.
3. UNS N10665Hastelloy B-2, 2.4617): Feem ntau muaj npib tsib xee, molybdenum, thiab hlau, nrog tsawg kawg nkaus ntawm chromium thiab tungsten.
4. UNS N10675 (ib.Hastelloy B-3, 2.4600): Muaj cov nickel, molybdenum, thiab hlau, nrog ntxiv ntawm chromium, cobalt, thiab tungsten.
