Txhua yam hais txog TP347 Stainless Hlau
ASTM A312 TP 347 Cov Lus Qhia Tshwj Xeebyog hom stainless hlau seamless yeeb nkab uas yog corrosion kuj heev -resistant.1.4550 (AISI 347), S34700feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau ua kom muaj qhov kub thiab txias.
Dab tsi ua rau ASTM A312 TP347 Cim?
CovASTM A 312 Cov Lus Qhiaspecification npog seamless, ncaj- seam welded, thiab hnyav hnyav- ua haujlwm welded austenitic stainless hlau kav npaj rau siab - kub thiab kev pabcuam corrosive.
Nyob rau hauv tus txheej txheem no,TIAB SA 347tau txais txiaj ntsig zoo tshaj cov qib txheem zoo li TP304 vim nws cov columbium ntxiv. Lub stabilization nrog columbium tshem tawm chromium carbide nag lossis daus nyob rau hauv qhov rhiab heev ntawm 800℃F txog 1500℃F (427℃rau 816 degree). Qhov no tseem ceeb tshuaj kom zoo dua tiv thaivintergranular corrosion (IGC), ua rau nws muaj kev ntseeg siab heev rau cov khoom uas yuav tsum tau ua tom qab-weld kho cua sov los yog kev pabcuam thermal.
Technical Note:Rau kev ntxhov siab heev - tawg thiab nkag mus - qhov yuav tsum tau muaj zog ntawm qhov kub siab tshaj 1000℃F, peb kuj tsim thiab muabASTM A312 TP347H (UNS S34709), uas nta cov ntsiab lus carbon ntau dua (0.04–0.10%) rau kev txhim kho siab - qhov kub thiab txias kev ruaj ntseg.

Chemical Composition & Mechanical Data
Qhov sib npaug ntawm qhov sib npaug ntawm cov hlau ua kom ntseeg tau tias qhov ua tau zoo nyob rau hauv siab siab - kev ua haujlwm siab.
Chemical Composition txwv (wt%) rau ASTM A312 / ASME SA312
Chromium (Cr):17.0% - 19.0% (Muab thawj oxidation thiab corrosion barriers)
Nickel (Ni):9.0% - 13.0% (Stabilizes cov qauv austenitic thiab nce toughness)
Columbium + Tantalum (Nb + Ta):10 x Carbon min, 1.10% max (Ua raws li cov khoom ruaj khov)
Cov pa roj carbon (C):0.08% max (0.04% - 0.10% rau Qib 347H)
Manganese (Mn):2.00% max

Sulfur (S):0.030% max
ASTM A312 UNS S34700 Yeeb Nkab Mechanical Properties:
- Tensile Strength: Ntau dua lossis sib npaug li 515 MPa
- Yield zog: Ntau dua los yog sib npaug rau 205 MPa
- Elongation: Ntau dua lossis sib npaug li 35%
1.4550 AISI 347 SS Seamless Yeeb Nkab Resistance rau Corrosion
Ib qho ntawm cov khoom tseem ceeb ntawmASTM A312 TP347 stainless hlau yeeb nkabyog nws tsis kam mus corrosion. Qhov no yog vim nws cov ntsiab lus siab ntawm chromium, uas tsim cov txheej txheem tiv thaiv saum npoo ntawm cov yeeb nkab, tiv thaiv xeb thiab lwm yam corrosion.
ASTM A312 Gr TP347 Kub Resistance
Intergranular Corrosion Immunity:Vim hais tias cov columbium ua ke nrog cov pa roj carbon zoo dua li chromium, qhov tseem ceeb tiv thaiv chromium barrier tseem sib npaug faib thoob plaws ntawm cov hlau nplej.
Extended Thermal Performance: 1.4550 AISI 347 SS kavtuav lub zog ntawm cov qauv thiab ntsuas qhov ua haujlwm siab txog 1500℃F (816 degree), yooj yim ua tau zoo tshaj tus qauv 304 lossis 316 qib hauv kev nruam- tshav kub loops.
Aggressive Media Protection:Ua kom muaj kev tiv thaiv zoo tshaj plaws hauv cov cheeb tsam oxidizing, cov roj qaub, thiab cov ntawv thov uas muaj cov organic / polythionic acids.
Key B2B Engineering Applications
Ua tsaug rau nws cov khoom siv hluav taws xob muaj zog,UNS S34700 seamless kavyog siv critically nyob rau hauv:
Refineries & Petrochemical Plants:Cov kua dej catalytic cracking units (FCCU), radiant tubes, thiab siab -pressure piping manifolds.
Cov Khoom Siv Hluav Taws Xob:Boiler tubes, superheater headers, thiab siab -siab chav faib network.
Kev ua tshuaj lom neeg:Cov khoom siv ua haujlwm nyob rau hauv siab -kub acid cycles thiab tshuaj huv si -shau khiav.
Aerospace & Exhaust Systems:Heavy- lub luag haujlwm sau lub nplhaib, lub cav tso pa tawm manifolds, thiab siab - qhov kub thiab txias expansion pob qij txha.
