ASTM A514 kalasi A mbale yachitsulo

ASTM A514 kalasi A ndi mtundu wa ASTM A514 zitsulo. Zomwe zatchulidwazi ndizoyenera kuzimitsidwa komanso kupsya mtima. Mipiringidzo ya ma graph pamakadi azinthu zomwe zili pansipa zikufanizira ASTM A514 giredi A ndi: zitsulo zopangidwa ndi aloyi m'gulu lomwelo (pamwamba), ma aloyi onse achitsulo (pakati), ndi nkhokwe yonse (pansi).

Chitsulo chachitsulo A514 Gulu A chili pansi pa chitsulo chokhazikika champhamvu cha zokolola zambiri ASTM A514/A514M.A514GrA ndi mbale yachitsulo yokhala ndi zitsulo zozimitsa ndi kutentha kutentha pamene ikugudubuza. 690Mpa makulidwe m'munsimu 65mm, ndi 620 Mpa makulidwe pamwamba 65mm, mphamvu yamakokedwe adzakhala mkati 760-895 Mpa. Wopanga atha kutenthetsanso mbale zomwe zikulephera kukwaniritsa zofunikira zamakina zomwe zafotokozedwazi pogubuduza mbale yachitsulo yolimba kwambiri A514GrA. Mayesero onse amakanika amayenera kubwerezedwanso zinthu zikatumizidwanso kuti zikawunikidwe.
