Stainless Hlau 309s Chev
Tus suav ntawm 309S yog Suav 0Cr23Ni13. Cov yam ntxwv thiab kev siv ntawm American standard S30908 (American AISI, ASTM) tau zoo dua 0Cr19Ni9 hauv kev tiv thaiv corrosion thiab kub ua hauj.
Lub 309S yog qhov sib txawv ntawm cov roj carbon qis dua 309 stainless hlau rau kev siv qhov twg vuam yuav tsum tau.Qhov qis cov pa roj carbon monoxide txo qis cov kem carbide hauv thaj chaw muaj cua sov nyob ze ntawm qhov chaw weld, uas yuav ua rau intercrystalline xeb (vuam yaig) ntawm cov hlau tsis xeb hauv qee qhov chaw ib puag ncig.

● Nta thiab kev siv:
SUS309S, 23CR-13NI siab hlau loj stainless hlau, zoo heev corrosion tsis kam thiab lub zog, haum rau qhov chaw nrog kev ua haujlwm kub txog 1000 ℃.
Nta - high alloy stainless hlau nrog zoo heev kub acid tiv thaiv thiab siab kub lub zog.
Lub Hom Phiaj - Kev siv tshuab ntxig ntxig, cua sov kho cua sov thiab cov cua sov ua kom sov
Kev tsim khoom thiab kev kho cua sov
Machinability
Kev ua cov qib 309S stainless hlau zoo ib yam li cov qib 304 stainless hlau.
vuam
Chav kawm 309S stainless hlau tuaj yeem tsim welded siv feem ntau tsis kam thiab fusion txoj kev.Qhov no steel tsis haum rau oxygenacetylene vuam.
Kub ua hauj lwm
Qeb 309 stainless hlau tuaj yeem rov kho ntawm 1177 ° C (2150 ° F) thiab 982 ° C (1800 ° F) rau kev ua kom sov.Qhov txheej txheem no yog ua raws cov cua txias kom ua tiav cov dej siab tshaj plaws.
Txias ua haujlwm
Txawm hais tias chav kawm 309S stainless hlau muaj qhov ua haujlwm siab ntawm kev ua haujlwm siab, nws tuaj yeem kos, chim siab, chim siab, thiab xuas nrig ntaus.Txawm li cas los xij, nws tau tso rau hauv tag nrho tom qab txias ua haujlwm txhawm rau txo kev ntxhov siab sab hauv.
ua txhaum
Hoob 309S stainless hlau tuaj yeem tau annealed ntawm 1038 txog 1121 ° C (1900 txog 2050 ° F) thiab tom qab ntawd quenched nrog dej.
tawv tawv
Qeb 309S stainless hlau yog qhov tsis muaj zog rau kev kho cua sov.Qhov qhov nyuaj thiab lub zog ntawm cov hlau zoo tuaj yeem txhim kho los ntawm kev ua haujlwm txias.
