904L (N08904,, 14539) super austenitic simbi isina tsvina ine 19.0-21.0% chromium, 24.0-26.0% nickel, uye 4.5% molybdenum. 904L super austenitic Stainless simbi isimbi yakaderera, yakakwira nickel, molybdenum austenitic stainless acid-resistant steel, inova zvinhu zvemuridzi zvakaunzwa kubva kuFrench H·S company. Iine yakanaka activation-passivation shanduko kugona, yakanakisa kusadzivirirwa kwecorrosion, yakanaka corrosion kuramba mune isiri-oxidizing asidhi senge sulfuric acid, acetic acid, formic acid, phosphoric acid, yakanaka pitting kuramba mune neutral chloride ion media, uye yakanaka crevice corrosion uye kusagadzikana corrosion kuramba. Inokodzera zvakasiyana-siyana zve sulfuric acid iri pasi pe 70 ° C, uye ine yakanaka corrosion resistance muacetic acid chero ipi zvayo yekuisa uye chero tembiricha iri pasi pekumanikidzwa kwakajairika, uye yakasanganiswa asidhi yefomic acid uye acetic acid.
AISI 904L Stainless simbi isimbi yakakwira-alloy austenitic Stainless simbi ine yakaderera zvakanyanya kabhoni. Iko kusanganiswa kwechromium yakakwira, nickel, molybdenum uye mhangura inopa simbi yakanaka yunifomu yekusagadzikana. Kuwedzerwa kwemhangura kunoita kuti ive yakasimba asidhi inodzivirira, inogona kuramba yakasiyana-siyana yeorganic uye inorganic acids, kunyanya chloride crevice corrosion uye stress corrosion cracking, haisi nyore kuva nemarara emarara uye kuputika, uye ine yakasimba pitting resistance. AISI 904L ine yakanaka corrosion resistance mu dilute sulfuric acid. The alloy isimbi yakakodzera dilute sulfuric acid yakasimba corrosive medium. Iyo zvakare inopesana nemvura yegungwa, ine yakanaka machinability uye weldability, uye inoshandiswa zvakanyanya mukuvaka, makemikari, ekurapa uye mamwe maindasitiri.
AISI 904L simbi isina tsvina inowanzoshandiswa mumareactors mu petroleum uye petrochemical equipment; sulfuric acid kuchengetedza uye midziyo yekufambisa, yakadai semagetsi ekupisa; flue gasi desulfurization midziyo mumagetsi emagetsi, senge shongwe, flue, zvivharo, zvemukati zvemukati, sprayers, mafeni, nezvimwe mune organic acid kurapwa masisitimu; midziyo yekuchenesa mvura yegungwa, yakadai semvura yegungwa inopisa kupisa; midziyo yeindasitiri yemapepa, sulfuric acid, nitric acid midziyo; midziyo yemakemikari, midziyo yekumanikidza, midziyo yechikafu senge acid kugadzira uye maindasitiri emishonga.

Madimikira ekugadzirwa neWomic Steel: 904L simbi isina simbi mapaipi anowanikwa akasiyana siyana ekugadzira saizi muWomic Steel Production mutsara, kusanganisira mapaipi asina musono nemapombi akaiswa. Iyo dhayamita yekunze yepombi isina musono inowanzobva pa3 kusvika ku720 mm (φ1 kusvika 1200 mm), ine madziro emadziro e0.4 kusvika 14 mm; dhayamita yekunze yepombi dzakasungwa kazhinji dzinobva pa6 kusvika ku508 mm, nehupamhi hwemadziro hwe 0.3 kusvika 15.0 mm.
Pamusoro pezvo, kune zvakare akasiyana maratidziro akadai semapaipi akaenzana uye mapaipi ane rectangular, simbi bar, mahwendefa, makoiri ane simbi isina tsvina yesarudzo yako muWomic Steel.
