A105 ndi nambala ya American ASTM, ndipo A imayimira chitsulo chopangidwa ndi mpweya wamba.
Dzina lokhazikika: zopangira zitsulo za kaboni pazinthu zapaipi.Chifukwa chitsulo chimodzi chokha chopangira chitsulo chomwe chimatchulidwa mu muyezo uwu, A105 ndi gawo lachitsulo chopangira kaboni.A105 ndi code yakuthupi, yomwe ndi yachitsulo chapadera ndipo ndi chitsulo chozizira.A105 ndi otsika mpweya zitsulo forging, ofanana 20 zitsulo.Pali miyezo iwiri, imodzi ndi American standard ASTM A105/A105M Carbon Steel Forgings for Piping Components, ndipo ina ndi Chinese standard GB/T12228-2006 Technical Conditions for Carbon Steel Forgings for General Purpose Valves.
