JIS G3103 SB480 Qolka iyo heerkulka qabow Cadaadiska Wessel Birta saxan

Saxanka birta birta ah ee Mo alloy SB480M waxaa inta badan loo isticmaalaa dhismaha weelasha cadaadiska rogid, iyo hoos ama le'eg si ay u dhumucdiisuna 38mm, sida giringiriyey waa ok. Marka laga reebo, Ultrasonic test waa lagama maarmaan, iyo xiisadda sare, la mid ah post welded daaweynta kulaylka waa in la doortay by isticmaalayaasha dhamaadka, sida saarayaasha kulaylka, dhirta kulaylka. darajada birta la mid ah waa ASTM A204GrB ilaa SB480M
QAYBKA BIRTA:
Dhumucda: 6MM ilaa 300MM,
Ballaca: 1500mm ilaa 4050mm,
Dhererka: 3000mm ilaa 15000mm
