Ngathi
Uluhlu lobubanzi
I-ASTM A179 yeetyhubhu ezinobubanzi obungaphandle obuphakathi kwe-3.2 -76.2 mm [NPS 1/8 - 3 intshi.].
Unyango lobushushu
Ubushushu bunyangwa kwi-1200℉ [650℃] okanye ngaphezulu emva kokudlula kokugqibela kokufunxa umkhuhlane.
Inkangeleko
Umbhobho wentsimbi ogqityiweyo akufuneki ube nesikali. I-oxidation encinci ayithathwa njengesikali.
