SA387 GR.12 CL2 Peehanga Waka Pereti maitai

I hangaia mo te whakamahi i roto i te ratonga pāmahana teitei, ko te ASME SA387 Grade 12 he maitai koranu waro molybdenum molybdenum mo te whakamahi i nga oko pehanga weldable me nga kohua ahumahi.
SA387 GR.12 CL2 Pressure Vessel Steel plate Whakaahuatanga:
A387 Grade 12 CL 1, A387 Grade 12 CL 2 kei raro i te paerewa tohu maitai ASTM A387 / A387M mo te pehanga oko pereti rino, te rino whakarewa me te Chromium-Molybdenum.Ko te pereti maitai rite SA387 Grade 12 CL 1 me te SA387 Grade 12 CL 2 kei raro i te American steel stamdard SA 387 / SA 387M.Ko enei papaa koranu rino katoa e tino hiahiatia ana mo nga kohua paiherea me nga oko pehanga&tanks.Rolling matotoru teitei o pereti he iti noa na te kaha o te hanganga ki te whakatutuki i nga whakaritenga rawa miihini kua tohua.
Mo te pereti pereti oko pehanga SA387 Grade 12 CL 1, me noho te kaha tensile i roto i te 380 ki te 550, ko te kaha tuku iti ko 230 Mpa.Mo SA387 Grade 12 CL 2 pereti oko pehanga, ko te kaha tensile kei te 450-585 Mpa me te tuku. me neke ake te tohu i te 275 Mpa. I tua atu i nga waahanga matua e rima, kei roto ano a Cr-Mo i te hanganga matū mo enei tira koranu.

Nga Paerewa Tohu mo ASME SA387 Alloy Steel Plate

ASME

  • SA20/A20M: Nga whakaritenga whanui mo nga pereti oko pehanga.
  • SA370: Whakataunga whakamatautau mo nga taonga miihini o te maitai
  • SA435/A435M: Mo te tirotiro ultrasonic kurupae tika o nga papa rino
  • SA577/A577M: Mo te whakamatautau kurupae koki ultrasonic o nga papa rino
  • SA578/A578M: ​​Mo te UT kurupae tika te tirotiro i nga pereti rino hurihuri i roto i nga tono motuhake
  • SA1017/A1017M: Whakaritenga mo nga pereti waka pehanga o te rino koranu, chromium-molybdenum-tungsten

Whakatakotoranga AWS

  • A5.5/A5.5M: He iti nga hiko koranu maitai mo te whakangungu rakau whakarewa pewa.
  • A5.23/A5.23M: He iti nga hiko koranu rino mo nga fulx mo te whakapiri pewa kua rukuhia.
  • A5.28/A5.28M: Mo te pewa parepare hau
  • A5.29/A5.29M: Mo te whaowhangai pewa whao rere.

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]
