Haynes 188 Plate (AMS 5608, W.Nr. 2.4683)
Haynes 188 (UNS R30188, W.Nr. 2.4683, AMS 5608) yog cobalt-nickel-chromium-tungsten solid- daws teeb meem muaj zog superalloy.
Qhov zoo tshaj plaws ntawm cov khoom siv no yog qhov sib ntxiv ntawm me me ntawm lanthanum-tsuas yog ob peb ntu ntawm ib txhiab. Thaum lub luag haujlwm ntawm lanthanum tuaj yeem ua suab tsis paub, nws tseem ceeb kom ntseeg tau tias cov yeeb yaj kiab oxide nyob ruaj khov thiab tsis sib cais. Thaum raug kub siab ntawm 1095℃rau ncua sij hawm, cov oxide nplai ntawm cov hlau zoo tib yam nyhav rau hlwv thiab flake tawm, tawm hauv cov hlau hauv qab ncaj qha mus rau qhov chaw corrosive. Nyob rau hauv sib piv, oxide zaj duab xis ntawm Haynes 188 "loj hlob" rau hauv lub substrate; nws yog tus kheej- kho thiab tsis tev tawm. Vim li cas cov hlau no yog tus qauv xaiv rau ntau xyoo rau cov nplaim taws thiab cov kav dej hloov pauv ntawm aero- cav combustion chambers? Nws tsis yog vim nws boasts lub siab tshaj plaws lub zog, tab sis vim hais tias ntawm nws exceptional ntev lub neej.
Tej kev siv
Cov ntawv thov ib txwm muaj xws li:
Aerospace: Combustor liners, hloov ducts, afterburner liners, nozzle flaps, thiab nplaim tuav
Gas turbines: Muaj roj turbine combustor Cheebtsam, foob rings, thiab nozzle partitions
High-kub muaj cua sov: Lub tshuab hluav taws xob hauv ob sab phlu, radiant tubes, thiab siab -kub fixtures
Nuclear fais fab / Tshuaj lom neeg kev lag luam: Cheebtsam uas yuav tsum tau ua hauj lwm rau siab -kub oxidation thiab kub corrosion los ntawm sulfates
Hauv cov ntsiab lus:Rau txhua daim ntawv nyias nyias - daim ntawv thov kev ua haujlwm siab tshaj 900℃uas yuav tsum tau ntev - lub sij hawm oxidation kuj nrog rau weldability thiab formability, Haynes 188 yog ib qho pov thawj, kev xaiv txhim khu kev qha txhawb nqa los ntawm ntau xyoo ntawm kev siv.

Daim ntawv ceeb toom hais txog qhov ntsuas kub: Haynes 188 yog qhov tsim nyog rau kev ua haujlwm ntev - ntawm qhov kub txog li 1095℃. Tshaj qhov kub no, oxidation accelerates thiab lub zog txo. Yog tias daim ntawv thov muaj qhov kub siab dua, Haynes 230 raug pom zoo.
Standards thiab Qib
Thaum peb cov neeg siv khoom tab tom nrhiav Haynes 188 phaj, cov qauv xav tau feem ntau yuav tsum tau lees paub raws li cov khoom siv rau daim ntawv thov:
| ASTM B 435 3 | General standard rau phaj / ntawv |
| TIAB SA 5608 | Cov qauv tseem ceeb rau aerospace- qib phaj / daim ntawv thiab sawb |
| ASME SB-435 | Standard rau kev siv lub nkoj siab |
| UNS R30188 | Feem ntau cov npe hu ua Unified Numbering System |
| W. Nr . 2.4683 | German standard designation |
| GH5188/GH188 | Suav teb chaws Standard grade designation |
Kev Sib Txuas Lus
Peb feem ntau ntseeg tias cov lus nug hauv qab no yuav pab tau zoo rau kev sib tham txog kev yuav khoom ntawm Haynes 188 phaj.

Summary of Our Experience
Factors cuam tshuam tus nqi:
Tus nqi ntawm Cobalt, Tungsten, thiab Nickel: Nrog rau cov khoom sib xyaw ntawm kwv yees li 40% cobalt, 14% tungsten, thiab 22% npib tsib xee, kev hloov pauv ntawm cov nqi ntawm peb cov hlau cuam tshuam ncaj qha rau cov nqi.
Specifications: Cov ntawv nyias nyias (<1mm) are more expensive than thick plates; narrow slit strips are more expensive than full-width sheets.
Nto tiav: Ci annealed yog kim dua li pickled.
Qhov xwm txheej: Cov mob laus yog kim dua li kev daws teeb meem-qhov mob annealed (vim muaj kev kho cua sov ntxiv).
Daim ntawv pov thawj yuav tsum tau: AMS aerospace-qib yog kim dua ASTM industrial- qib.
Kev yuav ntim: Cov luv nqi yog sib tham rau tonnage - qib xaj.
