ASTM A302 GR.B Mn-Mo Alloy Pressure Vessel Plate Plate Sharaxaadaha: Halabuurka Kiimikada iyo Qalabka Makaanikada:

ASTM A302 GR.B Mn-Mo Alloy Pressure Vessel Plate Plate Sharaxaadaha:

ASTM A302 qeexitaanka heerka caadiga ah ee taarikada weelka cadaadiska ee birta alloy, manganese molybdenum iyo manganese-molybdenum-nickel.
ASTM A302 waa nooc ka mid ah qeexida birta daawaha hoose ee daboosha 4 darajooyin kala duwan (A, B, C, D), Fasalka C iyo D ka kooban yahay kiimikaad Ni, oo leh dhumuc isku mid ah, dhalidda iyo xoogga xajinta ee darajada C waa isku mid B, halka heerka kordhinta darajada C uu sareeyo.
A302 saxan bir ah oo darajada B ah waa in sida caadiga ah lagu bixiyaa xaalad duuban. Taarikada waxaa laga yaabaa in lagu dalbado in la caadiyeeyo ama laga khafiifiyo walbahaarka, ama labadaba. Haddii A 302 Fasalka B ee ka sarreeya 50mm dhumucdiisuna waa in la caadiyeeyaa.
Farsamada Dheeraadka ah: Imtixaanka HIC | NACE MR0175 | Z15 | Z25 | Z35 |

Dhumucda: 6MM ilaa 300MM,
Ballaca: 1500mm ilaa 4050mm,
Dhererka: 3000mm ilaa 15000mm
