ASTM A302 Gulu A Mn-Mo Alloy Pressure Vessel Steel Plate

Izi zimakwirira mbale zachitsulo za manganese-molybdenum ndi manganese-molybdenum-nickel alloy zitsulo zopangira ma boiler owotcherera ndi zotengera zina zokakamiza. ASTM A302 ndi mtundu wa otsika aloyi zitsulo specifications chimakwirira 4 giredi (A, B, C, D), Gulu C ndi D lili mankhwala zikuchokera Ni, ndi makulidwe ofanana, zokolola ndi matenthedwe mphamvu ya kalasi C ndi chimodzimodzi kalasi. B, pamene mlingo wa elongation wa giredi C ndi wapamwamba kwambiri. Izi zimakwirira manganese-molybdenum ndi manganese-molybdenum-nickel alloy zitsulo mbale zomwe zimapangidwira makamaka zowotchera zitsulo ndi zotengera zina zokakamiza. ASTM A302 ndi mtundu wa otsika aloyi zitsulo specifications chimakwirira 4 giredi (A, B, C, D), Grade C ndi D lili mankhwala zikuchokera Ni, ndi makulidwe ofanana, zokolola ndi matenthedwe mphamvu ya kalasi C ndi chimodzimodzi kalasi. B, pomwe kuchuluka kwa giredi C ndikokwera. Amapangidwira Pressure Vessel, Boiler, Matanki Osungirako ndi Kusinthanitsa Kutentha mu Mafuta, Gasi Project.
