Kev ua cev tub
GENERAL Corrosion:301 Stainless hlau muaj qhov zoo tsis kam rau cov atmospheric corrosion thiab ntau qhov chaw tshuaj me me. Txawm li cas los xij, lawv cov khoom corrosion feem ntau tsis yog kom muaj zog raws li cov ntawm 18 {{{}} 8}} 8 / 304L.
Intergranular corrosion:Vim nws cov ntsiab lus carbon polerne (0.05-0.15%), 301 yog kev cuam tshuam rau qhov kub ntawm 450-850℃(842-1562 Qib F) rau lub sijhawm ntev. Qhov no tshwm sim vim kev tsim cov chromium carbides ntawm cov ciaj ciam av, tsim cov thaj chaw chromium-depleted uas muaj kev xeb.
Kev Kho Cua Sov
301 Stainless hlau tuaj yeem kho tshav kub siv cov hauv qab no:
Annealing kub:1010-1120℃(1850-2050℃f)
Cua txias:Kev ua kom txias sai (huab cua txias rau cov ntu nyias, dej txias rau cov tuab tuab) yog qhov tsim nyog kom tsis txhob muaj nag lossis daus.
Hais txog kev nyuaj siab:700-1000 Degree F (371-538 Qib) rau lub sijhawm tsib feeb txog tsib teev. Qis dua kub thiab sijhawm luv luv txo qis carbide nag lossis daus.
Ua haujlwm hauv Forge
Thaum pib kub:1093-1204 Qib (2000-2200 Qib F)
Kawg kub:927 degrees (1700 degrees f)
