Tshuaj muaj pes tsawg leeg ntawm ASTMA335P91 seamless steel yeeb nkab: carbon: 0 08 ~ 0.12, manganese: 0.3{{1{12}}}} ~0.60, phosphorus: Tsawg dua lossis sib npaug rau 0.020, sulfur Tsawg dua lossis sib npaug rau 0 . ~ 1.05, vanadium: 0.18 ~ 0.25, Nitrogen: 0.030 ~ 0.070, Nickel: Tsawg dua lossis sib npaug rau 0.40, Aluminium: Tsawg dua lossis sib npaug rau 0.040, Niobium: 0.06 ~ 0.10
Mechanical zog: tensile zog Ntau tshaj los yog sib npaug rau 585, yield zog Ntau tshaj los yog sib npaug rau 415, elongation: Ntau tshaj los yog sib npaug rau 20% cuam tshuam lub zog: Ntau tshaj los yog sib npaug rau 35J hardness: Tsawg dua los yog sib npaug rau 250HB
Hlau yeeb nkab specifications: txheej kab: 57mm ~ 762mm, phab ntsa thickness: 5.0 ~ 130mm
Cov txheej txheem ntau lawm: kub dov, forging dov, kev xa khoom: kev kho cua sov.
1. Sab nraud txoj kab uas hla: 3.5-250mm
2. Phab ntsa thickness: 0 5-30mm
3. Ntev: 2-12m
4. Kev ua haujlwm qib: P91
ASTM A335 P91 seamless steel yeeb nkab tsis tsuas yog muaj oxidation siab thiab siab kub chav corrosion kuj, tab sis kuj muaj kev cuam tshuam zoo toughness, siab thiab ruaj khov ntev yas thiab thermal zog zog. Thaum qhov kev pabcuam kub qis dua 620 degree, nws qhov kev cia siab yog siab dua li ntawm austenitic stainless hlau. Tshaj li 550 degree, qhov kev pom zoo tsim kom muaj kev ntxhov siab yog kwv yees li ob zaug ntawm T9 thiab 2.25Cr-1Mo steel.
ASTM A335 P91 Hlau Yeeb Nkab yog muaj nyob rau hauv nominal bore qhov ntau thiab tsawg los ntawm 1/8 nti mus rau 24 nti. Sab nraud diameters thiab phab ntsa thickness sib txawv, thiab lawv muaj nyob rau hauv ntau qhov sib txawv ntawm sch20 txog XXS. P91 chromium kav muaj nyob rau hauv phab ntsa thickness xws li 2 hli mus rau 14 hli thiab ntev mus txog 16000 hli. Cov kav dej tuaj yeem muaj ntau yam xws li puag ncig, square, duab plaub, thiab hydraulic, nrog rau qhov xaus, beveled xaus, thiab threaded xaus. Yog tias koj muaj ib qhov project uas yuav tsum tau P91 steel yeeb nkab, thov hu rau peb hauv lub sijhawm kom nug! sales@gneetube.com

FAQ
Q.Dab tsi yog qhov txawv ntawm ASTM A335 P91 Hom 1 thiab Hom 2?
A.ASTM A335 P91 Hom 1 & Hom 2 muaj qhov sib txawv me ntsis hauv cov ntsiab lus Mn, S, Si, N, Sn thiab Sb cov ntsiab lus, thiab Hom 2 muaj cov kev cai nruj dua ntawm cov ntsiab lus ntau dua li Hom 1. P91 hom 1 thiab 2 yuav tsum muaj hardness nyob rau hauv thaj tsam ntawm 190 txog 250 [HBW] lossis 196 txog 265 [HV] lossis 91 HRBW txog 25 HRC.
Q.Vim li cas xaiv koj?
A.Firstly zoo, tus nqi thib ob, peb tuaj yeem muab rau koj ob qho tib si. Peb cov qauv kev pabcuam: zoo zoo + tus nqi zoo + kev pabcuam zoo=cov neeg siv khoom ntseeg.
