FAQ
Puas yog TP439 sib nqus?
Yog lawm. Raws li ferritic stainless hlau, TP439 yog ferromagnetic nyob rau hauv tag nrho cov mob (annealed los yog txias - ua hauj lwm). Qhov no yog thawj txoj hauv kev kom paub qhov txawv ntawm 300-series austenitic stainless hlau yam tsis muaj tshuaj ntsuam xyuas.
TP439 vs TP304: Qhov twg zoo dua?
Nws nyob ntawm qhov chaw ua haujlwm:
Corrosion kuj: TP304 feem ntau muaj me ntsis zoo dua tag nrho corrosion kuj; Txawm li cas los xij, TP439 yog qhov zoo tshaj rau TP304 nyob rau hauv cov nqe lus ntawm kev tiv thaiv kev nyuaj siab corrosion cracking (SCC) nyob rau hauv chloride ib puag ncig, qhov twg TP304 feem ntau tsis ua hauj lwm.
Tus nqi: TP439 feem ntau yog tus nqi ntau dua - siv tau vim nws tsis muaj npib tsib xee (Ni).
Thermal expansion: TP439 muaj qis coefficient ntawm thermal expansion, ua rau nws ruaj khov nyob rau hauv daim ntawv thov uas muaj kub cycling.
Qhov txawv ntawm TP439 thiab TP430 yog dab tsi?
TP439 yog qhov tseem ceeb ntawm kev txhim kho ntawm TP430. Titanium (Ti) ntxiv rau TP439 los pab kev vuam thiab tiv thaiv "sensitization" (carbide nag lossis daus), qhov txheej txheem TP430 nyhav dhau los ua nkig thaum vuam.
TP439 puas tuaj yeem siv rau hauv siab -cov ntawv thov kub?
Yog lawm. TP439 muaj oxidation zoo heev thiab tuaj yeem tiv taus kub txog li 850℃(1560℃F). Nws yog dav siv nyob rau hauv automotive tso systems (manifolds, mufflers) thiab tshav kub exchangers rau tsev qhov cub.
