Corrosion Resistance:
Kev tiv thaiv corrosion hauv oxidizing ib puag ncig yog los ntawm 18 mus rau 19% chromium uas 304 alloys muaj.
Kev tiv thaiv rau cov organic acids tsis zoo yog qhov tshwm sim ntawm 9 mus rau 11% npib tsib xee uas 304 alloys muaj.
Qee lub sij hawm, alloy 304L tuaj yeem pom qhov qis qis dua qhov siab dua carbon Alloy 304;txwv tsis pub, 304, 304L, thiab 304H tej zaum yuav raug suav hais tias ua tau zoo ib yam hauv feem ntau qhov chaw corrosive.
Alloy 304L yog qhov zoo dua rau kev siv nyob rau hauv ib puag ncig txaus corrosive los ua intergranular corrosion ntawm welds thiab tshav kub-tshem tawm tsam ntawm cov alloys raug.
Thaum tshav kub kub Resistance:
Zoo oxidation kuj nyob rau hauv intermittent kev pab rau 1600 ° F thiab nyob rau hauv tas li ntawd mus rau 1690 ° F.
Kev siv txuas ntxiv ntawm 304 hauv 800-1580 ° F ntau yam tsis pom zoo yog tias tom qab aqueous corrosion kuj tseem ceeb.
Qib 304L yog tiv taus ntau dua rau cov nag lossis daus thiab tuaj yeem ua kom sov rau hauv qhov kub thiab txias.
Cov khoom ntawm 304 Alloy
Welding yam ntxwv:
Cov khoom siv vuam zoo heev;post-weld annealing tsis tas yuav tsum tau thaum vuam nyias ntu.Ob qhov kev txiav txim siab tseem ceeb hauv kev tsim cov pob qij txha hauv austenitic stainless hlau yog:
preservation ntawm corrosion kuj
zam kev tawg
Processing - Kub forming:
Rau forging, kub uniformity rau 2100 / 2300 ° F
Tsis txhob forge hauv qab 1700 ° F
Forging tuaj yeem ua cua txias yam tsis muaj kev phom sij ntawm kev tawg
Kev Ua Haujlwm - Cold forming:
Nws cov qauv austenitic tso cai rau nws ua kom sib sib zog nqus tsis muaj qhov nruab nrab annealing, Ua qhov no stainless hlau qib ntawm kev xaiv hauv kev tsim cov dab dej, hollow-ware thiab saucepans.
Cov qhab nia no ua haujlwm hnyav sai.Txhawm rau txo cov kev ntxhov siab uas tsim los ntawm kev sib sau loj lossis kev sib tw, cov khoom yuav tsum yog tag nrho annealed los yog kev ntxhov siab nyem annealed sai li sai tau tom qab tsim.
Machineability:
Kev siv cov chips tawg yog qhia vim hais tias cov chips tuaj yeem ua stringy.Stainless hlau ua hauj lwm harden ceev, hnyav zoo feeds, ntse tooling, thiab ib tug nruj set-up yuav tsum tau siv.of txiav hauv qab ntawm cov ua hauj lwm-hardened txheej uas tshwm sim los ntawm yav dhau los passes.
