Cov yam ntxwv tseem ceeb ntawm ASTM A335 P91 Hom 2 raj
ASTM A335 P91 Hom 2 yog hlau chrome-moly alloy uas paub txog nws lub zog tshwj xeeb, tiv taus kub, thiab lub zog nkag. Nws yog cais ua hlau ferritic (CSEF) uas muaj zog nkag, ua rau nws zoo tagnrho rau kev siv kub thiab siab. Cov khoom siv dhau los ntawm cov txheej txheem kho cua sov tshwj xeeb:

Normalizing ntawm 1050 ° C.

Cua txias rau 200 ° C.

Kub hnyiab ntawm 760 ° C.

Cov txheej txheem no ua rau nws lub zog thiab kev ruaj khov, ua rau nws yog qhov kev xaiv zoo dua rau cov chaw xav tau kev pab.

Cov chaw tsim roj av: Cov cua sov, cov khoom siv ua roj, thiab cov kev pabcuam roj av.

Cov kav dej kub siab: Haum rau kev khoov, flanging, thiab vuam.

Cov Tshuaj Lom Zem ntawm ASTM A335 P91 Steel Tubes
Cov tshuaj lom neeg ntawm P91 ua kom nws ua tau zoo dua:

Cov pa roj carbon: 0.08% - 0.12%

Manganese: 0.30% - 0.60%

Chromium: 8.00% - 9.50%

Molybdenum: 0.85% - 1.05%

Vanadium: 0.18% - 0.25%

Nitrogen: 0.030% - 0.070%

Lwm cov ntsiab lus: Nickel, txhuas, columbium, titanium, thiab zirconium nyob rau hauv kev tswj hwm tus nqi.

Cov Khoom Siv Kho Tshuab
Lub Zog Tensile: Yam tsawg kawg nkaus 85,000 PSI (585 MPa).

Lub Zog Tawm: Yam tsawg kawg nkaus 60,000 PSI (415 MPa).

Vuam thiab Kho Kub ASTM A335 P91 Cov Tubes Hlau
Vuam P91 yuav tsum ua raws li cov txheej txheem kom tswj tau nws cov khoom:

Kev Ua Ntej: Tseem ceeb kom tiv thaiv kev tawg vim yog hydrogen.

Kev tswj qhov kub thiab txias ntawm qhov hla dhau: Tswj xyuas siv cov tshuab cua sov induction niaj hnub.

Kev kho cua sov tom qab vuam (PWHT): Tseem ceeb heev rau kev ua tiav qhov microstructure xav tau thiab zam kev ua tsis tiav.
