SA387 GR.12 CL1 Alloy Pressure Vessel pereti maitai

Ko te A387 Koeke 12 CL 1 kei raro i te paerewa tohu rino ASTM A387/A387M mo nga pereti rino oko pehanga, koranu maitai me te Chromium-Molybdenum
SA387 GR.12 CL1 Alloy Pressure Vessel steel plate Whakaahuatanga:
A387Gr12CL1 ipu pereti rino he iti rawa te kaha o te tuku i te 275 Mpa, me te kaha tensile i roto i te 450-585 Mpa. Pressure oko maitai pereti SA387 Grade 12 CL 1 kei roto i te paerewa American ASME SA 387 /SA 387M.Boiler maitai paraharaha A387 Grade 12 Cl 1 e rite ki ASTM A387 /A387M. Ka rite ano enei taonga rino ki te tohu maitai A 20/A 20M. Ko enei whakaritenga e whakaatu ana i nga tikanga me nga tikanga whakamatautau me te whakamatautau ano, nga rereketanga o te rahi me te taumaha, te kounga me te whakatikatika i nga hapa, te tohu, te uta, me era atu.

Te Maamaa Wera mo SA387 Chrom Moly Alloy Steel Plate

Ko te pereti maitai koranu moly moly i raro i te ASME SA387 ka patua te rino, me te whakamaaramatanga ma te whakamaarama, ma te whakamaarama me te whakamaarama. Mena ka whakaaehia e te kaihoko, ka tere te whakamahana mai i te pāmahana austenitizing ma te pupuhi hau, te tinei wai ranei, ka whai i te whakamahana, ko te iti rawa o te pāmahana whakamahana me penei i raro iho i te tepu:
Kōeke Pāmahana, °F [°C]
2, 12 me 11 1150 [620]
22, 22L, 21, 21L me te 9 1250 [675]
