Lus piav qhia luv luv:
STAINLESS STEEL 329 ROUND BAR
329 S32900 1.4460 stainless hlau
Cov hlau qib 1.4460 AISI 329 yog stainless, acid resistant, duplex steel nrog txhim kho machinability. Txij li cov hlau yog machinability txhim kho, nws yog tsim rau zus tau tej cov ntsiab lus nrog kev machining. Cov hlau muaj corrosion kuj zoo heev tshwj xeeb hauv cov chloride-cov kabmob ib puag ncig thiab muaj kev tiv thaiv ntxiv rau pitting corrosion, crevice corrosion, kev nyuaj siab corrosion cracking thiab corrosion qaug zog. Nws tseem muaj zog thiab toughness.
1.4460 cov chaw siv feem ntau yog:
- Propeller- thiab Pumpshafting
- Pump- thiab Valveparts
- Pistons
- Cov tshuaj nplaum
- Bolts
- Txiv ntseej

Corrosion kuj
329 muaj Pitting Resistance Equivalent (PRE) ntawm ≥31.
329 muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking hauv chloride ib puag ncig. Cov qib kuj tseem muaj kev tiv thaiv zoo rau kev xeb hauv cov kua qaub tawm, ua tsaug rau cov ntsiab lus chromium siab thiab alloying nrog molybdenum.
Microstructure
Nyob rau hauv cov tshuaj annealed thiab quenched mob Sanmac 329 muaj ib tug austenitic-ferritic microstructure, uas yog dawb los ntawm grain- ciam teb carbides thiab intermetallic theem. Cov ntsiab lus ferrite yog 55-75%.
Zoo machinability, weldability thiab formability
1.4460 yog ua tau rau vuam thiab tsis tas yuav welded nrog vuam consumables zoo ib yam li cov niam txiv. Cov hlau yuav tsum tau welded raws li cov khoom siv austenitic nrog cov cua kub tsawg li tsawg tau. Nws tuaj yeem ua tau ob qho tib si txias- thiab kub tsim. Cov hlau yooj yim dua rau tshuab thiab nws muaj qhov ua tau zoo dua qub, tab sis me ntsis corrosion kuj tsis zoo dua li 1.4462.
KEV NPAJ
Cov khoom yuav tsum tau muab tshuaj annealed ntawm 1870/2010ºF (1020/1100ºC) thiab dej quenched. Kwv yees li ntawm qhov sib npaug ntawm austenite thiab delta ferrite yuav raug tsim tom qab cov tshuaj annealing.
MACHINABILITY
Qib no nyuaj heev rau tshuab, tej zaum ntau tshaj li qhov qub 18/8 austenitics. Hom 309 tsuas muaj li ntawm 50 feem pua ntawm cov machinability Performance index ntawm hom 316. Nws raug nquahu kom siv cov tshuab zoo tshaj plaws thiab cov cuab yeej siv rau kev ua haujlwm ntawm cov khoom ua los ntawm qib no.
