SA387 GR.12 CL2 Cadaadiska Weelka Birta saxanka Sharaxaada: Halabuurka Kiimikada iyo Qalabka Makaanikada:

SA387 GR.12 CL2 Cadaadiska Weelka Birta saxanka Sharaxaada:

A387 Fasalka 12 CL 1, A387 Fasalka 12 CL 2 waxay ku hoos jiraan heerka ASTM A387 / A387M sifeynta weelka cadaadiska birta, steel Alloy leh Chromium-Molybdenum. waa hoos American steel stamdard SA 387 / SA 387M. All kuwan taarikada birta daawaha loogu talagalay ugu horrayn kuleyliyaha welded iyo weelasha cadaadiska & taangiyada. Rolling dhumucdiisuna waxay ugu badnaan taarikada xaddidan oo kaliya by awoodda ka kooban si ay u buuxiyaan shuruudaha hantida farsamo ee cayiman.
Wixii saxan bir ah markabka cadaadiska SA387 Fasalka 12 CL 1, xoogga xajintu waa in ay ahaataa gudahood 380 si ay u 550, ugu yar ee wax soo saarka waa 230 Mpa. dhibicdu waa inay ka sarraysaa 275 Mpa. Marka laga reebo shanta walxood ee ugu waaweyn, Cr-Mo waxa kale oo ay ku jirtaa isku-dhafka kiimikaad ee birta alloy-ga ah.

Daawaynta kulaylka ee SA387 Chrom Moly Alloy Steel Plate

Saxanka birta birta ah ee moly alloy ee hoos yimaada ASME SA387 waa in la dilo birta, iyada oo kulayl ahaan lagu daaweeyaa iyada oo la tirtirayo, caadiyeynayo iyo dabci. Ama haddii uu ku heshiiyo iibsadaha, qaboojinta degdega ah ee heerkulka hagaajinta hawada hawada ama dareere deminta, oo ay ku xigto heerkulka, heerkulka heerkulka ugu yar waa inuu ahaadaa sida shaxda hoose:
