Chithunzi cha ASTM A519machubu amapangidwa ndi njira yopanda msoko ndipo azikhala otentha kapena oziziritsa monga momwe tafotokozera.
Kwa machubu ozungulira okhala ndi m'mimba mwake osapitirira 12 3/4 in (325 mm).
Machubu achitsulo amathanso kupanga masikweya, makona anayi, kapena mawonekedwe ena momwe amafunikira.
ASTM A519 akhoza m'gulu malinga ndi zitsulo:Chitsulo cha Carbonndi Alloy Steel.
Chitsulo cha carbonyagawidwa muLow Carbon MT(Mechanical Tubing),High Carbon SteelndiDesulfurized kapena Rephosphorized, kapena zonse ziwiriChitsulo cha Carbon, kuti zigwirizane ndi zosowa zosiyanasiyana zamafakitale ndi zochitika zogwiritsira ntchito.
Ngati palibe kalasi yomwe yatchulidwa, opanga ali ndi mwayi woperekaMT1015 kapena MTX1020magiredi.
M'mimba mwake: 13.7 - 325 mm;

Chitsulo chikhoza kupangidwa ndi ndondomeko iliyonse.
Chitsulo chikhoza kuponyedwa mu ingots kapena kuponyedwa chingwe.
Machubu adzapangidwa ndi andondomeko yopanda msokondipo idzakhala yotsirizidwa yotentha kapena yozizira, monga momwe zafotokozedwera.
Machubu achitsulo opanda msoko ndi machubu opanda nsonga zowotcherera ponseponse.
Machubu oziziritsa oziziraamalimbikitsidwa kuti azifuna kwambiri kulondola kwa dimensional ndi mawonekedwe apamwamba.
Chodetsa nkhawa kwambiri ndi kutsika mtengo komanso kulimba kwa zinthu,chitoliro chachitsulo chotentha chomalizakungakhale kusankha koyenera.
Chotsatira ndi kupanga ndondomeko ya chitoliro chachitsulo chosasunthika chotentha.
Wopanga zitsulo azisanthula kutentha kwa chitsulo chilichonse kuti adziwe kuchuluka kwa zinthu zomwe zafotokozedwa.
