ASTM A302 GR.C Mn-Mo-Ni Alloy Pressure Vessel pā kila

ʻO ASTM A302 Grade C ʻo Manganese-molybdenum-nickel alloy boiler plate steel. E pepehi ʻia ke kila o A302 Grade C a e kūlike me nā koi nui o ka palaoa. ʻO ka paila kila A203 Grade C e kau ʻia i ka hoʻāʻo ʻana e hoʻoholo ai i ka ikaika tensile, ka hoʻoulu ʻana i ka ikaika, a me ka elongation. I ka wā e ʻōwili ai i ka SA302 Grade C ma lalo o ke alakaʻi kila NACE MR0175, hoʻāʻo HIC, SCC, hoʻāʻo SSC e hana ʻia i loko o kā mākou hale hana wili no ka waiwai kila SA302 Grade C. ʻO nā ho'āʻo ʻenehana ʻē aʻe, e like me PWHT, DWTT, E koho ʻia ka hoʻāʻo ʻana i ka wela wela e nā mea hoʻohana hope inā koi lākou.
