- Tom qab ua haujlwm kub, forgings yuav tsum txias kom tsawg dua 1000 "F [538 degree] ua ntej kev kho cua sov raws li Table 1.
- Tsawg-Alloy, Ferritic, thiab Martensitic Stainless Steels-Low-alloy, ferritic, thiab martensitic stainless hlau yuav tsum tau kho cua sov raws li qhov yuav tsum tau muaj
Tshooj thiab Cov lus xav tau rau kev kho cua sov.
aLiquid quenching-Tom qab kev pom zoo los ntawm tus neeg yuav khoom, cov kua quenching ua raws li tempering tau tso cai, thiab qhov kub thiab txias yuav tsum tau siv rau txhua qib.
bMarking - Cov kua quenched thiab tempered qhov chaw yuav tsum tau cim nrog cov ntawv "QT".
c Tsis tas li ntawd, Qib 1, Qib 2 Qib F1, F2, thiab F12 cov ntaub ntawv yuav raug kho kom sov rau qhov kub tsawg kawg nkaus ntawm 1200F [650 degree] tom qab qhov kawg txias los yog kub sib sau.
- Austenitic thiab ferritic-austenitic stainless hlau-Austenitic thiab ferritic-austenitic stainless hlau yuav tsum tau kho cua sov raws li qhov yuav tsum tau muaj ntawm ntu thiab rooj.
a Tsis tas li ntawd, thaum qhov kub ntawm cov forgings tsis tsawg tshaj li qhov tsawg kawg nkaus kev daws teeb meem kub teev nyob rau hauv Table 1, tam sim ntawd tom qab kub ua hauj lwm, austenitic qib steel forgings (tshwj tsis yog rau qib F 304H, F 309H, F 310, F 310H, F 316H, F 321, F 321H, F 347, F 347H, F 348, F 348H, F 45, thiab F 56) tej zaum yuav yog (a) Lub quenching yog nqa tawm ib los ntawm ib tug sai sai.
b Yog tias yuav tsum siv txoj kev kho cua sov tshwj xeeb, saib Cov Lus Qhia Ntxiv S8.
- Kev kho cua sov tuaj yeem ua tiav ua ntej machining.
- Wrought los yog dov tuav - Wrought los yog dov austenitic stainless hlau tuav tso cai nyob rau hauv seem 5.4 rau machining ntawm cylindrical qhov chaw thiab qhov chaw machined los ntawm cov tuav, uas tsis yuav tsum tau kev kho cua sov tom qab machining, yuav tsum tau muab nyob rau hauv raws li cov kev kho cua sov yuav tsum tau teev nyob rau hauv A 479/A 479M los yog nyob rau hauv tus qauv no, thiab tau tso cai kom maj mam txias-drawn thiab straightened tom qab kev kho cua sov.
