Thaum Lub Xya Hli 8, 2023, peb tau xa ASTM A335 P92 cov yeeb nkab hlau tsis muaj hlau mus rau Ltalis, thiab xa lawv raws sijhawm. Lub sijhawm no, peb tau ua 100% cov khoom ntim khoom siv, suav nrog PVC ntim, hnab ntim khoom, thiab cov ntawv ntim khoom puv nrog daim txhuam cev, uas tuaj yeem siv dua tag nrho. Cov hlua hlau siv los khi cov yeeb nkab, thiab cov yeeb nkab nyob ib sab ntawm lawv tau ntim nrog daim ntawv tiv thaiv kev sib tsoo thiab daim txhuam cev puv nrog daim txhuam cev, thiab thaum kawg ntim rau hauv cov thawv ntoo. Sab nraud ntawm lub thawv ntoo, peb kuj siv txoj siv hlau muaj zog heev los kho lub thawv, kom tiv thaiv sab hauv thiab sab nraud ntawm cov yeeb nkab tag nrho.
Kev xa khoom los ntawm cov neeg siv khoom Italian tau tsim lub hauv paus zoo dua rau peb lub khw European, thiab peb tos ntsoov rau peb txoj kev koom tes tom ntej!
ASTM A335 P92 yog cov yeeb nkab hlau tsis sib xyaw, uas feem ntau yog siv rau hauv cov chaw tsim hluav taws xob thermal hauv xyoo tas los no, feem ntau yog rau cov kav dej loj thiab cov kav dej rov ua kom sov.
A335 P92 cov 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:0.15~0.25 N:0.03~0.07 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 mechanical zog: tensile zog ≥ 620Map, yield zog ≥ 440Mpa, elongation tom qab tawg ≥ 20%
ASEM SA335 P92 Seamless Alloy Steel Pipe Kev 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, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711, 762, thiab lwm qhov ntau thiab tsawg kuj tuaj yeem hloov 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 cov generator loj
Cov yeeb nkab hlau ASTMA335 tus qauv Asmeskas sib raug rau cov hlau qib P11, P12, P5, P9, P91 khoom
A335 P11 yog cov lej khoom siv uas tau muab los ntawm ASTM (American Society for Testing and Materials), thiab tus qauv hauv tebchaws yog 15CrMo, uas yog cov khoom siv hlau alloy.
ASTM A335 P5 sib raug rau cov hlau sib xyaw hauv tsev: 1Cr5Mo. Cov qauv hlau ntawm 1Cr5Mo yog martensite, uas muaj kev tiv thaiv oxidation zoo ntawm li 650 degrees Celsius, lub zog thermal zoo hauv qab 600 degrees Celsius, kev nqus tau zoo thiab kev ua kom sov thermal, thiab siv dav hauv cov turbines pa.
Tus qauv Asmeskas astm a335p91 sib npaug rau tus qauv hauv tebchaws 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Cov khoom siv sib xyaw ntawm P91 (cov khoom xyaw wt%):
C 0.08~0.12; Mn 0.30~0.60; Si 0.20~0.50; 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
Cov yeeb nkab hlau tsis muaj seamless Asmeskas tus qauv a106 seamless steel yeeb nkab kuj yog cov khoom lag luam uas muaj ntau heev.
ASTM A106 seamless steel yeeb nkab yog ib feem ntawm 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 tus tom kawg yog sib npaug rau cov khoom siv hauv tsev 20 #.
