309/309s Stainless Steels (UNS designation S30900/S30908) yog austenitic, chromium-nickel
stainless steels uas muab zoo heev corrosion kuj thiab tshav kub kuj ntxiv zog zoo nyob rau hauv chav tsev thiab siab kub. Hom 309s yog qhov qis carbon version ntawm 309 uas txo qis carbide nag lossis daus thiab txhim kho weldability. Cov alloys no tsis yog-sib nqus li annealed thiab ua me ntsis sib nqus thaum ua haujlwm txias.
Cov alloys no muaj kev tiv thaiv oxidation zoo heev, siab -qhov kub thiab txias tsis kam.

FABRICATION
Hom 309 thiab 309S Stainless Steels tuaj yeem yob tsim, stamped thiab kos tau yooj yim.
Hauv - txheej txheem annealing feem ntau yuav tsum tau txo qis hardness thiab nce ductility
Vuam
Cov chav kawm austenitic ntawm stainless hlau feem ntau suav hais tias yog weldable los ntawm qhov ntau
fusion thiab tiv thaiv txheej txheem. Kev txiav txim siab tshwj xeeb yuav tsum tau them rau qhov siab dua
coefficient ntawm thermal expansion kom tsis txhob warping thiab distortion. Hom 309 thiab 309S feem ntau yog
suav tias muaj weldability ze li qhov sib npaug ntawm cov alloys feem ntau ntawm cov chav kawm no, Hom 304
ib 304l. Thaum xav tau ib qho kev sib txuas, AWS E/ER 309 thiab 310 feem ntau tau teev tseg. Qauv 309
thiab 309S tau paub zoo hauv cov ntaub ntawv siv thiab cov ntaub ntawv ntau ntxiv tuaj yeem tau txais los ntawm txoj kev no
FAQ
Q. Kuv puas tuaj yeem muaj cov qauv txiav txim rau cov khoom siv stainless hlau phaj?
A: Yog lawm, peb txais tos cov qauv txiav txim los kuaj thiab xyuas qhov zoo. Cov qauv sib xyaw ua ke tau txais.
Q. Yuav ua li cas txog lub sijhawm ua haujlwm?
A: Qauv xav tau 3-5 hnub;
Q. Koj puas muaj MOQ txwv rau stainless hlau phaj khoom xaj?
A: Tsawg MOQ, 1pcs rau kev kuaj xyuas yog muaj
Q. Koj yuav xa cov khoom li cas thiab yuav siv sijhawm ntev npaum li cas thiaj tuaj txog?
A: Peb feem ntau xa los ntawm DHL, UPS, FedEx lossis TNT. Nws feem ntau yuav siv 3-5 hnub los txog. Lub dav hlau thiab hiav txwv shipping kuj xaiv tau. Rau cov khoom loj, nkoj freight yog nyiam.
Q. Puas yog nws luam kuv lub logo ntawm cov khoom?
A: Yog. OEM thiab ODM muaj rau peb.
Q: Yuav ua li cas kom ntseeg tau qhov zoo?
A: Mill Test Certificate yog muab nrog cov khoom xa tuaj. Yog tias xav tau, Kev Tshuaj Xyuas Thib Peb tau txais
