Ahaanshaha mid ka mid ah darajooyinka birta aan wanaagsanayn ee ugu caansan suuqa, tuubooyinka SA312 tp304 waxay caddaynayaan inay yihiin walxo la isku halleyn karo oo loo isticmaali karo dhammaan warshadaha muhiimka ah ee kala duwan. Sababta loo yaqaan Alloy class 304 Stainless Steel 304 Tubooyinka inay caan yihiin waa inay si fiican u caabisay daxalka dhowr dhexdhexaad ah. Tan waxa u sabab ah maaddo sare oo chromium ah oo loo isticmaalo isku-darka tuubooyinka birta aan-dhalatada lahayn 1.4301.

Dhuumaha birta ah ee 304 waxay leedahay awood adag oo aad u fiican, xitaa marka tuubooyinkani ay soo gaadheen heerkul hooseeya. Birta 304 ee birta welded ma aha oo kaliya inay muujiso iska caabbinta wanaagsan ee daxalka atmospheric, laakiin sidoo kale cuntada iyo sidoo kale cabitaannada iyo kiimikooyin badan oo organic iyo kuwa aan organic ahayn. astm a312 tp304 seamless iyo SS 304 ERW tuubada waxay u adkeysan kartaa daxalka warbaahinta aan soo sheegnay, xitaa si dhexdhexaad ah oksijiinta iyo si dhexdhexaad ah u yareynaya bay'ada.
