Yog - thiab kev puas tsuaj feem ntau nyob mus ib txhis.
Ntau lub Hoobkas sivAISI 304 stainless hlau xaimhlua nyob ze rau qhov cub, cov khoom siv kho cua sov, lossis hauv siab -rhiav kub. 304 yog kub dua- tiv taus ntau dua li cov pa roj carbon steel, tab sis nws tsis yog "universal high-kub tov."
Peb qhov kev pheej hmoo tseem ceeb:
1. Sensitization (450℃- 850 degree)
Hauv qhov tseem ceeb no, chromium carbides tsim ntawm cov ciam teb nplej, tawm hauv chromium - thaj chaw depleted. Tom qab txias, txoj hlua yuav poob mus tas li los tiv thaiv corrosion - nws yuav xeb sai sai hauv qhov chaw ntub dej lossis ntug hiav txwv.
2. Poob lub zog ntawm qhov kub thiab txias
Tshaj 300 degree, tensile lub zog poob qis heev. Ntawm 600 degree, lub zog tsuas yog ib nrab ntawm nws chav ntsuas kub. Qhov no txo koj cov npoo kev nyab xeeb rau kev nqa cov haujlwm.
3. Lubricant burnout & thermal qaug zog
Internal lubricants carbonize los yog evaporate, ua rau hnav sai dua. Kev rov ua cua sov thiab cua txias ua rau muaj kev ntxhov siab thermal, ua rau qaug zog thaum ntxov.
Cov txheej txheem kev lag luam
- Surface temperature >200 degree: siv ceev faj
- Surface temperature >300 degree: feem ntau cov qauv tsis pom zoo AISI 304 rau nqa
- Rau kev ua haujlwm siab -kev pabcuam kub: xaiv 321 (titanium-stabilized), 347 (niobium-stabilized), lossis 310S tshav kub-cov hlau tsis muaj zog
Tsis paub tias304 steel hlau hluapuas haum rau koj daim ntawv thov? Kev xaiv tsis ncaj ncees nyob rau hauv siab - qhov kub thiab txias ib puag ncig tuaj yeem raug nqi ntau. Xa peb koj qhov kub thiab txias, ib puag ncig, thiab kev thauj khoom tshwj xeeb, thiab peb yuav tshuaj xyuas koj qhov kev xaiv dawb.
