I-ASTM A302 yeBanga A i-Mn-Mo Alloy Pressure Vessel Steel Plate

Lokhu kucaciswa kuhlanganisa amapuleti ensimbi e-manganese-molybdenum kanye ne-manganese-molybdenum-nickel ahloselwe ikakhulukazi amabhayela ashiselwe neminye imikhumbi yokucindezela. I-ASTM A302 iwuhlobo lokucaciswa kwensimbi eyingxubevange ephansi ehlanganisa amabanga ama-4 ahlukene (A, B, C, D), iBanga C kanye no-D liqukethe ukwakheka kwamakhemikhali i-Ni, enogqinsi olufanayo, isivuno namandla aqinile eBanga C kuyafana neBanga. B, kuyilapho izinga lokwelulwa kwebanga C lingaphezulu.
