Qhov txawv ntawm SS 310 thiab SS310S
| Element | UNS S31000 (Qib 310) | UNS S31008 (Qib 310S) |
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.25% | Tsawg dua lossis sib npaug li 0.08% (Low Carbon) |
| Chromium (Cr) | 24.0 – 26.0% | 24.0 – 26.0% |
| Nickel (Ni) | 19.0 – 22.0% | 19.0 – 22.0% |
| Silicon (Si) | Tsawg dua lossis sib npaug li 1.50% | Tsawg dua lossis sib npaug li 1.50% |
1. UNS S31008(SS310S Stainless Hlau Tube):
- Tsawg carbon version: S31008 yog qis carbon version ntawm S31000. Nws cov ntsiab lus carbon yog txog li 0.08%.
- Weldability zoo dua: Cov ntsiab lus carbon tsawg ua rau nws tsis tshua muaj kev cuam tshuam rau kev nkag siab (grain ciam carbide nag lossis daus), uas yog ib qho teeb meem tshwm sim hauv cov ntawv thov kub thiab tuaj yeem ua rau intergranular corrosion. Qhov no ua rau alloy 310s zoo dua rau kev siv vuam.
- Kev kub siab ua haujlwm: Ua kom zoo oxidation tsis kam mus txog 1100℃(2012℃F).
2. UNS S31000 (SS 310 Stainless hlau):
- Cov ntsiab lus carbon siab dua: S31000 muaj cov ntsiab lus carbon ntau dua me ntsis (txog li 0.25%).
- Kev ua haujlwm siab kub: Alloy 310 tuaj yeem tiv taus qhov kub thiab txias me ntsis, tswj kev ua haujlwm ruaj khov thiab oxidation tsis kam hauv kev siv txuas ntxiv mus txog 1150℃(2100℃F).
Ntsiab Mechanical & Kev Ua Haujlwm Sib txawv
1. Weldability thiab Intergranular Corrosion
VimUNS S31000muaj txog li 0.25% carbon, nthuav tawm nws mus rau vuam kub ua rau carbide nag lossis daus nyob rau hauv grain ciam teb (sensitization). Qhov no ua rau lub tshav kub tsis muaj zog- thaj tsam cuam tshuam (HAZ) thiab tawm hauv cov yeeb nkab tsis muaj zog rau intergranular corrosion.
Hloov pauv,UNS S31008 (310S)txwv carbon rau 0.08%. Qhov no tsawg - carbon tsim suppresses carbide nag lossis daus thaum lub sij hawm vuam, ua 310S seamless thiab welded kav yog qhov kev xaiv zoo tshaj plaws rau cov txheej txheem welding thiab complex piping manifolds.
2. Qhov Kev Pab Cuam Tshaj Plaws Tshaj Plaws & Ua Tau Zoo
Thaum cov pa roj carbon qis hauv S31008 txhim kho nws lub peev xwm tsim khoom, nws txo qis nws qhov ntev - lub sij hawm siab - kub creep zog piv rau cov qauv S31000 qib.
UNS S31000 (310):Superior zog nyob rau hauv tas li txhua yam load ntawm huab cua kub. Nws withstands nruam raug mus txog1150 ° F (2100 ° F)nyob rau hauv qis- kev nyuaj siab.
UNS S31008 (310S):Zoo heev rau thermal cycling ib puag ncig qhov twg cov khoom nthuav dav thiab cog lus. Nws tuav tau zoo heev oxidation kuj nyob rau hauv tas li huab cua kev pab mus txog rau1100℃(2012℃F).
Cov ntawv thov kev lag luam: Qhov twg rau Deploy 310 vs 310S
Vim lawv cov ntsiab lus siab chromium thiab npib tsib xee, ob qho tib si cov ntaub ntawv zoo hauv kev txo qis, carburizing, thiab sulfidizing ib puag ncig, tab sis lawv tus kheej lub zog hais tias qhov twg lawv siv tau zoo tshaj plaws:
Deploy S31008 (310S Pipes & Tubes):Qhov zoo tshaj plaws rau cov khoom sib dhos hnyav, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom sib txuas, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov kav dej tshuaj uas tom qab -weld annealing tsis tau.
Deploy S31000 (Standard 310):Qhov zoo tshaj plaws rau cov raj radiant, chav boiler tube hangers, refractory thauj tog rau nkoj bolts, thiab muffle furnaces ua hauj lwm tsis tu ncua nrog tsawg vuam kev nyuaj siab.
