General Properties
Alloy 310 (UNS S31000) yog ib qho austenitic stainless hlau tsim los siv rau hauv cov ntawv thov kub corrosion resistant. Cov hlau tiv thaiv oxidation mus txog 2010oF (1100oC) nyob rau hauv me me cyclic tej yam kev mob.
Vim tias nws cov chromium siab thiab cov ntsiab lus nickel nruab nrab, Alloy 310 yog resistant rau sulfidation thiab tuaj yeem siv rau hauv nruab nrab carburizing cua.
Qhov hnyav dua carburizing cua ntawm cov txheej txheem thermal feem ntau yuav tsum tau nickel alloys xws li 330 (UNS N08330). Alloy 310 tuaj yeem siv rau hauv me ntsis oxidizing, nitriding, cementing thiab thermal cycling daim ntaub ntawv, txawm hais tias, qhov siab tshaj plaws kev pab kub yuav tsum tau txo. Alloy 310 kuj pom kev siv hauv cov ntawv thov cryogenic nrog qis sib nqus permeability thiab toughness mus rau -450oF (-268oC). Thaum rhuab ntawm 1202 - 1742oF (650 - 950oC) cov hlau yog raug rau sigma theem nag lossis daus. Ib qho tshuaj annealing kev kho mob ntawm 2012 - 2102oF (1100 - 1150oC) yuav rov qab ua kom muaj zog.
310S (UNS S31008) yog qhov qis carbon version ntawm cov hlau. Nws yog siv rau kev yooj yim ntawm fabrication. 310H (UNS S31009) yog ib qho kev hloov kho carbon siab tsim rau kev txhim kho creep tsis kam. Feem ntau cov nplej loj thiab cov ntsiab lus carbon ntawm lub phaj tuaj yeem ua tau raws li 310S thiab 310H cov cai.
Alloy 310 tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov qauv kev tsim khoom hauv khw.

Corrosion Resistance
Kev ntub dej Corrosion
Alloy 310 tsis yog tsim los rau kev pabcuam hauv qhov chaw ntub dej corrosive. Cov ntsiab lus siab carbon, uas yog tam sim no los txhim kho creep zog, muaj kev cuam tshuam rau aqueous corrosion kuj. Lub alloy yog nquag mus rau intergranular corrosion tom qab lub sij hawm ntev raug ntawm kub kub. Txawm li cas los xij, vim nws cov ntsiab lus chromium siab (25%), Alloy 310 yog corrosion resistant ntau dua li cov alloys kub resistant.
Kub kub Corrosion
Lub siab chromium (25%) thiab silicon (0.6%) cov ntsiab lus ntawm Alloy 310 ua rau nws tiv taus kub kub corrosion nyob rau hauv feem ntau qhov chaw ua haujlwm. Kev khiav hauj lwm kub yog teev hauv qab no.
Oxidizing tej yam kev mob (max sulfur ntsiab lus - 2 g / m3)
1922 degree F (1050 degree) kev pabcuam txuas ntxiv
2012 degree F (1100 degree) ncov kub
Oxidizing tej yam kev mob (max sulfur ntau dua 2 g / m3)
1742 degree F (950 degree) siab tshaj plaws kub
Cov pa oxygen tsawg (max sulfur cov ntsiab lus - 2 g / m3)
1832 degree F (1000 degree) siab tshaj plaws kub
Nitriding los yog carburizing cua
1562 - 1742 degree F (850 - 950 degree) siab tshaj plaws
Cov hlau tsis ua haujlwm zoo li Alloy 600 (UNS N06600) lossis Alloy 800 (UNS N08800) hauv kev txo qis, nitriding lossis carburizing cua, tab sis nws ua tau zoo tshaj cov hlau tsis muaj cua sov hauv cov xwm txheej no.
