Nsonsonoe 3 na ɛwɔ dade a ɛnyɛ den 304 ne austenitic dade a ɛnyɛ den ntam:
Nea edi kan no, ɛsono sɛnea abien no su te:
1. Nneɛma a ɛwɔ 304 dade a ɛnyɛ den mu: 304 dade a ɛnyɛ den yɛ ade a wɔtaa yɛ wɔ dade a ɛnyɛ den mu, a ne kɛse yɛ 7.93g/cm³, a wɔsan frɛ no 18/8 dade a ɛnyɛ den wɔ adwuma no mu. Ɔhyew a ɛkɔ soro a ɛko tia 800 °C, wɔ su a ɛma adwumayɛ yɛ yiye na ɛyɛ den kɛse.
. High silicon austenitic stainless steel no wɔ corrosion resistance pa wɔ nitric acid a wɔahyɛ no den ho.Nea
ɛto so abien no , abien no a wɔde di dwuma no yɛ soronko:
1. Dadeɛ a ɛnyɛ den 304 a wɔde di dwuma: ɛfata sɛ wɔde yɛ aduane, wɔkora so na wɔde fa. wɔ processability pa ne weldability. Mprɛte mu ɔhyew sesa, bellows, ofie nneɛma (adesuakuw 1 ne 2 pon so nneɛma, nkuku, dan mu nsu afiri, nsu a wɔde yɛ ɔhyew, nsu a wɔde yɛ nsu, bathtubs); Auto parts (mframa wipers, mufflers, molded products), nnuruyɛ mu nneɛma, adansi nneɛma, nnuru, aduan ho adwumayɛbea , kuayɛ, po so ahyɛn afã horow, ne nea ɛkeka ho 304 Stainless Steel yɛ ɔman no mu aduan a wogye tom a ɛyɛ dade a ɛnyɛ den.
2. Austenitic stainless steel a wɔde di dwuma: wɔde di dwuma kɛse wɔ nnwuma ne dan mu nneɛma a wɔde siesie fie ne aduan ne aduruyɛ mu. Esiane sɛ austenitic stainless steel no agyapade a ɛyɛ pɛpɛɛpɛ na ɛyɛ papa nti, wɔde adi dwuma kɛse wɔ nnwuma ahorow mu.
Nea ɛto so abiɛsa no, ɛsono akuw abien no:
. Foforo nso ne Division of National Standard, Japanfo gyinapɛn, Amerika gyinapɛn ne nea ɛkeka ho.
. Wɔ C a ɛba fam no mu no, CR a ɛwɔ mu no yɛ 18% ~ 28%, na Ni a ɛwɔ mu no yɛ 3% ~ 10%. Dade binom nso wɔ nneɛma a wɔde afrafra te sɛ MO, Cu, Si, NB, Ti, ne n.
Saa dadeɛ yi wɔ austenitic ne ferritic stainless dadeɛ su. Sɛ wɔde toto ferrite ho a, ɛwɔ plasticity ne toughness a ɛkorɔn, enni dan mu hyew a ɛyɛ mmerɛw, na ɛma intergranular corrosion resistance ne welding adwumayɛ tu mpɔn kɛse.
Bere koro no ara mu no, ɛsan nso kura 475 °C brittleness ne ɔhyew conductivity a ɛkorɔn a ferritic stainless steel, na ɛwɔ su a superplasticity. Sɛ wɔde toto austenitic stainless steel ho a, ɛwɔ ahoɔden kɛse na ɛma ahoɔden a ɛko tia intergranular corrosion ne chloride stress corrosion no tu mpɔn kɛse. Duplex stainless steel wɔ pitting corrosion resistance a ɛkyɛn so na ɛsan nso yɛ dade a ɛnyɛ den a ɛkora nikel so.
Paw Hangao Tech (seko mfiri) . Ɔsoro precision stainless dade welded pipe production line austenitic tube mill afiri . sɛ wubedi dade a ɛnyɛ den 304 ne austenitic dade a ɛnyɛ den a wɔde weld ayɛ ho dwuma bere koro mu. Archway nhyehyɛe ne roller bearing no yɛ nea eye sen biara na ama shaft runout no so atew na ama dade paipu no pɛpɛɛpɛyɛ atu mpɔn kɛse.
