304 Birta aan Birta lahayn ee Wareega Bar

304 bir ah oo siman oo siman waxa loola jeedaa dusha siman, kaas oo lagu farsameeyo dhamaystirka duubista, diirinta ama nadiifinta sawirka qabow;waxaa inta badan loo isticmaalaa kiimiko kala duwan, cunto, dhar iyo qalab kale oo farsamo iyo ujeeddooyin qurxineed oo kala duwan.Waxa loogu yeero 304 ahama birta madow wareega ama 304 usha birta ah (usha madow) waxaa loola jeedaa birta wareegsan ee dusha sare waa madow iyo qallafsanaan, si toos ah kulul-rogid, been abuur ah, ama annealed iyada oo aan habayn lakabka oksaydhka ee dusha.

304: 18-8 bir ah, heerka GB tixraaca waa 0Cr18Ni9;Halbeegga hirgelinta Ameerikaanka: ASTM A276.

GB: C≤0.07;Si≤1.0;Mn≤2.0;P≤0.045;S≤0.03;Ni: 8.0-11.0;C: 17.0-19.0

ASTM: C≤0.08;Si≤1.0;Mn≤2.0;P≤0.045;S≤0.03;Ni:8.0-11.0;C:18.0-20.0

304 steel waa tan ugu badan ee loo isticmaalo birta chromium-nickel, kaas oo leh iska caabin daxalka wanaagsan, iska caabinta kulaylka, heerkulka hooseeya iyo sifooyinka farsamada.Waxay u adkaysataa daxalka jawiga.Haddii ay tahay jawiga warshadaha ama meel aad u wasakhaysan, waxay u baahan tahay in la nadiifiyo wakhtiga si looga fogaado daxalka.[1]

Marka loo eego habka wax soo saarka, 304 birta wareegsan ee birta ah waxay u qaybsan tahay saddex nooc: rogid kulul, foorno iyo sawir qabow.Qeexitaanka kulul ee duuban 304 birta wareegsan ee birta ah waa 5.5-130 mm.Waxaa ka mid ah: 5.5-25mm yar yar oo ah 304 bir wareeg ah oo birta ah ayaa inta badan lagu bixiyaa xariijimo toosan, oo inta badan loo isticmaalo birta birta, boolal iyo qaybo farsamo oo kala duwan;ama si toos ah gobolka wareega, sida badeecooyinka dhammeeyey ee dib-u-habaynta dambe.304 bir wareeg ah oo ka weyn 25 mm ayaa inta badan loo isticmaalaa in lagu soo saaro qaybo makaanik ah ama daloolin tuubooyin bir ah oo aan lahayn.[2]

304 bir ah oo wareeg ah oo miisaankeedu yahay qaabka xisaabinta aragtida:

Miisaanka mitirkiiba (kg) = dhexroor * dhexroor * 0.00623
