Wax-soo-saarka
Qalabka birta kaarboon ee ASTM A234 waxaa laga yaabaa in laga sameeyo tuubooyin aan fiicneyn, tuubooyinka alxanka leh ama taarikada iyadoo la qaabeynayo hawlgallada riixitaanka, daloolinta, soo saarista, foorarsiga, alxanka fiyuuska, mashiinnada, ama isku darka laba ama ka badan oo hawlgalladan ah.Dhammaan alxanka oo ay ku jiraan alxanka alaabta tuubada ee laga sameeyay qalabyada waa in loo sameeyaa si waafaqsan Qeybta IX ee ASME.Daawaynta kulaylka ka dib 1100 ilaa 1250F[595 ilaa 675°C] iyo baadhitaanka shucaaca waa in la sameeyaa ka dib habka alxanka.
