Thaum tshav kub kub Resistant hlau(feem ntau hu ua High-Temperature Stainless Steel) yog tsim los tswj cov qauv kev ruaj ntseg thiab tshuaj lom neeg kev ncaj ncees ntawm elevated temperatures qhov twg standard structural steels yuav poob.
Peb qib flagship,AISI 310S (1.4845 / 25Cr-20Ni), ua raws li kev lag luam benchmark rau siab -kub siv. Nrog qib siab ntawmchromium (25%)thiabnpib tsib xee (20%), nws tsim ib qho kev tiv thaiv oxide txheej uas tiv taus scaling thiab oxidation mus txog1150 degree. Nws yog dav siv rau kev tsim khoomCov khoom siv hluav taws xob, cov raj boiler, thiab cov khoom siv hluav taws xobuas yuav tsum tau siabcreep rupture zog(tsis kam mus deformation nyob rau hauv load raws sij hawm).

Cov yam ntxwv tseem ceeb thiab qhov zoo
Oxidation Resistance
Cov ntsiab lus siab Chromium tsim kom nruj, tus kheej - kho qhov ntsuas uas tiv thaiv cov pa oxygen los ntawm kev nkag mus thiab rhuav tshem cov hlau matrix, txawm tias ntawm 1100℃.
Creep zog
Tsis zoo li tus qauv 304 stainless uas deforms sai heev nyob rau hauv load thaum kub kub,Austenitic Heat Resistant Steels (310S) maintain high tensile strength at temperatures >600 degree.
Thermal Fatigue Resistance
Tsim los tiv thaiv cua sov thiab cua txias yam tsis muaj qhov tawg (qhov tseem ceeb rau cov pob tawb thiab cov tais).
Carburization Resistance
Qib nrog cov nickel siab (zoo li 310S) tiv thaiv cov pa roj carbon monoxide los ntawm cov cua sov hauv cua sov, tiv thaiv cov khoom los ntawm kev tawg.
Tej kev siv
Thaum tshav kub kub Resistant Steel yog lub caj qaum ntawm siab -kub kev lag luam:
- Muaj Furnaces:Linings, qhov rooj, kiv cua, thiab muffle raj rau annealing thiab hardening furnaces.
- Petrochemical:Cracking hlab thiab pigtails hauv kev tsim ethylene.
- Kev tsim hluav taws xob:Superheater raj, boiler txhawb, thiab thee burners.
- Cement & Ceramics:Rotary kiln qhov chaw thiab refractory anchors (siv309S / 310S).

FAQ
Q1: Qhov txawv ntawm 309S thiab 310S yog dab tsi?
A1: Kub txwv & Nickel ntsiab lus.
310S muaj ~ 20% npib tsib xee thiab ua haujlwm txog 1150 degree. Nws yog qhov kev xaiv hwm rau huab cua kub heev.
309S muaj ~ 13% npib tsib xee thiab ua haujlwm txog 1000 degree. Nws yog tus nqi ntau dua -zoo rau qhov kub nruab nrab.
Q2: Dab tsi yog "creep" hauv steel?
A2: Creep yog qeeb, mus tas li deformation ntawm cov khoom nyob rau hauv load ntawm kub kub. Txheem steel yuav ncab thiab nws thiaj li tsis ua hauj lwm nyob rau hauv lub qhov cub kub. Thaum tshav kub kub- cov hlau tsis muaj zog yog tshwj xeeb alloyed los tiv thaiv qhov ncab no, ua kom lub neej ua haujlwm ntev.
Q3: Puas yog 310S sib nqus?
A3: Tsis yog. 310S yog austenitic, yog li nws tsis yog- sib nqus nyob rau hauv qhov mob annealed. Txawm li cas los xij, ferritic cua sov- cov hlau tsis muaj zog (xws li 1Cr25Si2 / 446) yog cov hlau nplaum.
Q4: Koj puas tuaj yeem muab cov cua sov- tiv taus steel rau lub cav li qub?
A4: Yog. Peb muab 4Cr10Si2Mo (SUH3) puag ncig tuav, uas yog tus qauv martensitic cua sov-cov hlau tsis muaj zog siv rau kev tsim khoom noj thiab tso pa tawm hauv cov tshuab hluav taws xob sab hauv.
