ASTM A335 P92 Seamless Ferritic Alloy Steel Yeeb Nkab

ASTM A335 P92 yog ib qho kev qhia tshwj xeeb rau seamless ferritic alloy steel kav, zoo ib yam li P91 tab sis nrog cov ntsiab lus chromium thiab molybdenum siab dua, muab kev txhim kho nkag siab ntawm qhov kub siab.

Ntau lawm Specification: ASTM A335 P92 qhia txog qhov yuav tsum tau ua rau seamless ferritic alloy steel yeeb nkab haum rau cov kev pabcuam kub kub, tshwj xeeb hauv kev siv hluav taws xob tsim hluav taws xob.

Khoom Specification: Cov khoom muaj pes tsawg leeg rau ASTM A335 P92 muaj xws li alloying ntsiab xws li chromium, molybdenum, thiab tej zaum vanadium.

Cov Khoom Siv Cov Ntsiab LusCov tshuaj lom neeg muaj pes tsawg leeg rau ASTM A335 P92 suav nrog:

Chromium: 8.50-9.50%

Molybdenum: 0 30-0.60%

Cov pa roj carbon: 0 07-0.13%

Manganese: 0 30-0.60%

Silicon: 020-0.50%

Phosphorus: 0.020% max

Sulfur: 0.010% max

Vanadium: 0 15-0.25%

Nitrogen: 0 03-0.07%

Mechanical Properties: ASTM A335 P92 cov kav dej muaj cov khoom siv zoo heev, tshwj xeeb tshaj yog creep zog, ntawm qhov kub siab. Tej yam khoom muaj xws li:

Tensile zog: 620 MPa (90 ksi) yam tsawg kawg nkaus

Tawm Zog: 440 MPa (64 ksi) yam tsawg kawg nkaus

Elongation: 20% yam tsawg kawg nkaus

Hardness: 250 HBW siab tshaj plaws

Daim Ntawv Thov Scope: ASTM A335 P92 cov kav dej yog siv rau hauv high-temperature thiab high-pressure applications, xws li chav pipelines, boiler tubes, superheater tubes, thiab tshav kub exchanger tubes nyob rau hauv fais fab nroj tsuag thiab petrochemical nroj tsuag, uas yuav tsum tau txhim kho creep zog.

Kev tsim khoom thiab kev ceev faj: ASTM A335 P92 cov kav dej feem ntau yog tsim los siv cov txheej txheem kub ua tiav lossis txias tiav. Zoo ib yam li P91, yuav tsum tau saib xyuas tshwj xeeb los tswj cov txheej txheem kho cua sov kom ntseeg tau tias qhov xav tau microstructure thiab txhua yam khoom tiav.

Feem ntau muab Specifications thiab qhov ntau thiab tsawgASTM A335 P92 cov kav dej feem ntau muab nrog cov lus qhia thiab qhov ntau thiab tsawg zoo ib yam li P91:

Sab nraud txoj kab uas hla: 1/2 "- 36"

Phab ntsa Thickness: SCH 20, SCH 40, SCH 80, SCH 160, SCH XS, SCH XXS

Length: Ib qho Random, Ob Chav Random, Txiav Lengths

End Finish: Plain End, Beveled End, Threaded

Common Q&A:

Q: Dab tsi yog qhov txawv ntawm P91 thiab P92?

A: Qhov sib txawv tseem ceeb nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg, qhov twg P92 muaj ntau dua chromium thiab molybdenum cov ntsiab lus piv rau P91, muab kev txhim kho creep zog ntawm qhov kub thiab txias.

Q: P92 puas tuaj yeem siv sib hloov nrog P91?

A: Thaum ob qho kev qhia tshwj xeeb tsim nyog rau cov ntawv thov kub, P92 feem ntau yog xaiv rau nws lub zog nkag siab zoo hauv cov xwm txheej xav tau ntau dua.

Q: Puas muaj kev txiav txim siab tshwj xeeb thaum vuam P92 kav?

A: Yog lawm, zoo ib yam li P91, cov txheej txheem vuam kom zoo thiab kev kho cua sov tom qab vuam yog qhov tseem ceeb kom tsis txhob muaj teeb meem xws li tawg thiab ua kom cov khoom siv kho mob xav tau.
