I-ASTM A302 GR.B Mn-Mo Alloy Pressure Vessel Plate Yensimbi

Ukucaciswa okujwayelekile kwe-ASTM A302 kwamapuleti omkhumbi wengcindezi kunsimbi ye-alloy, manganese molybdenum kanye ne-manganese-molybdenum-nickel.
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.
Ipuleti lensimbi le-A302 Lebanga B ngokuvamile lizohlinzekwa esimweni esigoqelwe. Amapuleti angase a-odwe ajwayeleke noma akhululeke ukucindezeleka, noma kokubili. Uma u-A 302 weBanga B ngaphezu kuka-50mm ngogqinsi kufanele ujwayeleke.
