Thaum Lub Xya Hli 8, 2023, peb xa ASTM A335 P92 seamless alloy steel kav mus rau Ltalis, thiab xa lawv raws sijhawm. Lub sijhawm no, peb tau ua 100% kev ntim khoom ntxiv, suav nrog cov ntim PVC, lub hnab ntim khoom, thiab cov ntawv ntim cov ntaub so ntswg, uas tuaj yeem rov qab siv tau raws li tag nrho cov hlua hlau siv los ntim cov kav dej, thiab cov raj ntawm lawv tau ntim nrog. anti-kev sib tsoo npuas daim ntawv thiab daim txhuam cev sau ntawv, thiab thaum kawg tau ntim rau hauv cov thawv ntoo. Nyob rau sab nraud ntawm lub thawv ntoo, peb kuj siv ib txoj hlua hlau uas muaj zog heev los kho lub thawv, thiaj li tiv thaiv cov yeeb nkab sab hauv thiab sab nraud ntawm tag nrho.
Kev xa khoom los ntawm cov neeg siv khoom Italian tau tsim lub hauv paus zoo dua rau peb cov lag luam European, thiab peb tos ntsoov rau peb txoj kev koom tes tom ntej!
ASTM A335 P92 yog ib qho hlau tsis muaj seamless steel yeeb nkab, uas yog siv rau hauv thermal fais fab nroj tsuag hauv xyoo tas los no, feem ntau yog rau cov kav dej loj thiab cov kav dej ua kom sov.
A335 P92 tshuaj lom neeg muaj pes tsawg leeg: C: 0.07 ~ 0.13 Si: ≤0.50 Mn: 0.30 ~ 0.60 P≤0.020 S≤0.010 Cr: 8.50 ~ 9.50 Mo: 0.30 ~ 0.60Ni≤0.40 V: 0.70N: Al ≤0.02 Ti: ≤0.01 Zr≤0.01Nb: 0.04 ~ 0.09 W: 1.5 ~ 2.0 B: 0.001 ~ 0.006
ASTM A335 P92 seamless alloy steel yeeb nkab txhua yam khoom: tensile zog ≥ 620Map, yield zog ≥ 440Mpa, elongation tom qab tawg ≥ 20%
ASEM SA335 P92 Seamless Alloy Steel Yeeb Nkab Xa Khoom: Normalizing + Tempering
ASEM A335 P92 seamless alloy steel yeeb nkab loj: 60.3-765 * 2-120, feem ntau siv txoj kab uas hla 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 3555.8, 10, 660, ib. 711, 762, thiab lwm qhov ntau thiab tsawg kuj tuaj yeem kho raws li cov neeg siv khoom xav tau.
Daim ntawv thov tseem ceeb ntawm ASME SA335 P92 alloy steel yeeb nkab: feem ntau yog siv rau hauv kev tsim cov superheaters thiab reheaters rau lub tshuab hluav taws xob loj.
American txuj ASTMA335 alloy yeeb nkab sib raug rau steel qib P11, P12, P5, P9, P91 khoom
A335 P11 yog cov khoom siv code uas tau muab los ntawm ASTM (American Society for Testing and Materials), thiab cov qauv sib xws hauv tebchaws yog 15CrMo, cov khoom siv hlau alloy.
ASTM A335 P5 sib raug rau cov hlau hauv tsev: 1Cr5Mo. Cov qauv hlau ntawm 1Cr5Mo yog martensite, uas muaj qhov zoo oxidation tsis kam ntawm 650 degrees Celsius, zoo thermal zog hauv qab 600 degrees Celsius, zoo poob siab absorbing thiab thermal conductivity, thiab yog dav siv nyob rau hauv chav turbines.
American standard astm a335p91 yog sib npaug rau lub teb chaws tus qauv 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Cov khoom muaj pes tsawg leeg ntawm P91 (cov khoom xyaw wt%):
C 0.08 ~ 0.12; 0.30 ~ 0.60 hli; 0.20 ~ 0.50 hli; P ≤0.02; S ≤0.01; Cr 8.0 ~ 9.5;
Mos 0.85 ~ 1.05; V 0.18–0.25; Nb 0.06 ~ 0.1; N 0.03 ~ 0.07; Al ≤0.04; Ni ≤0.4
American standard seamless steel yeeb nkab a106 seamless steel yeeb nkab kuj yog ib yam khoom uas muaj ntau heev.
ASTM A106 seamless steel yeeb nkab belongs rau American standard steel yeeb nkab, A106 suav nrog A106-A, A106-B. Tus qub yog sib npaug rau cov khoom siv hauv tsev 10 #, thiab tom kawg yog sib npaug rau cov khoom siv hauv tsev 20 #.
