304/304L Stainless Simbi Tube Pipe
Tsanangudzo
ASTM A312 ASTM A269 ASME SA 213 / ASTM A213 TP304, EN 10216-5 1.4301 simbi isina simbi inosiyana ye18% chromium - 8% nickel austeniticstainless simbi chubhu, inonyanya kuzivikanwa uye inonyanya kushandiswa mumhuri yesimbi isina tsvina.Iyi simbi isina tsvina inotariswa seyakasiyana siyana yekushandisa pane yakanaka corrosion resistance, kugadzirwa nyore, kuumbwa kwakanaka, uye kusimba kwepamusoro nehuremu hwakaderera.
304 Stainless Simbi ndiyo yakajairwa "18/8" simbi isina tsvina;ndiyo inonyanya kushandiswa uye inoshandiswa zvakanyanya simbi isina tsvina, inowanikwa muhuwandu hwakawanda hwezvigadzirwa, mafomu uye kupera kupfuura chero ipi zvayo.Iyo ine yakanakisa kuumba uye welding maitiro.Iyo yakaenzana austenitic chimiro cheGiredhi 304 inoita kuti ive yakadzika yakadzika yakakweverwa pasina yepakati annealing, izvo zvaita kuti giredhi iri rive nesimba mukugadzirwa kwesimbi isina tsvina yakaita se sink, hollow-ware uye saucepan.Kune aya maapplication zvakajairika kushandisa akakosha "304DDQ" (Deep Drawing Quality) akasiyana.
Giredhi 304 iri nyore bhureki kana roll inoumbwa kuita zvakasiyana-siyana zvekushandisa muindasitiri, yekuvaka, uye yekufambisa minda.Grade 304 zvakare ine yakatanhamara welding hunhu.Post-weld annealing haidiwi kana welding zvikamu zvitete.
Giredhi 304L, iyo yakaderera kabhoni vhezheni ye304, haidi post-weld annealing uye saka inoshandiswa zvakanyanya muheavygauge component (inodarika 6mm).Giredhi 304H ine yakakwira kabhoni yemukati inowana application pane yakakwirira tembiricha.Iyo austenitic chimiro chinopawo aya mamakisi kusimba kwakanyanya, kunyangwe pasi kune cryogenictemperature.
