ASME SA387 GR.22 CL2 Boiler and Pressure Vessel Steel plate

Ko te ASME SA387 he pereti rino molybdenum molybdenum chromium i hangaia mo te kohua me nga oko pehanga i hangaia mo te ratonga pāmahana teitei.
ASME SA387 GR.22 CL2 Pressure Vessel Steel plate Whakaahuatanga:
SA 387 GR.22 CL.2 PATE kei te chromium o 2.25% me te molybdenum o 1% me te kaha ki te mahi i roto i te 600 Deg C pāmahana e karapoti ana i te pai. Ko nga pereti rino molybdenum me te chromium e mahi pai ana i te rerekee o te pāmahana e whakarato ana i nga mahi tino pai. Ko te taapiri o te molybdenum i roto i te koranu SA 387 kei te piki ake te kaha o nga pereti i te pāmahana nui ake. Ano hoki, kei te whakarato i te kaha pai ki te aukati i te waikura me te waikura ma te whakanui ake i te riaka kupenga. He pai tenei ki te aukati i te kaikawe mai i te rino e memeha ana, ka pai te kaha o te wera wera, ka waiho hei whiringa pai mo te hau e karapoti ana. Ano, he pai te weldability. No reira, ka tino hiahiatia tenei pereti puta noa i te ao.

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]
