Hlau Phaj
309/309s Stainless Steels (UNS designation S30900/S30908) yog austenitic, chromium-nickel
stainless hlau uas muab zoo heev corrosion kuj thiab tshav kub kuj ntxiv zog zoo
ntawm chav tsev thiab qhov kub siab. 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-magnetic li annealed thiab
ua me ntsis sib nqus thaum txias ua haujlwm.
Cov alloys no muaj kev tiv thaiv oxidation zoo heev, siab -qhov kub thiab txias tsis kam.

Corrosion kuj
309 thiab 309S muab kev tiv thaiv corrosion zoo heev. Lawv muaj ntau resistant rau marine
Cov huab cua ntau dua li Hom 304. Lawv muaj kev tiv thaiv siab rau sulfite cawv thiab muaj txiaj ntsig zoo rau kev tuav
nitric acid, nitric -sulfuric acid sib tov, thiab acetic, citric, thiab lactic acids.
Cov ntaub ntawv no feem ntau suav hais tias yog cua sov- tiv thaiv cov hlau. Lawv scaling puas tsuaj
Qhov kub thiab txias yog li 2000℃F (1093 degree). Lawv pom zoo scaling tsis kam nyob rau hauv ob qho tib si nruam thiab sib quas ntus kev pab cuam, tab sis cov alloys yuav tsum tsis txhob siv saum toj no 1800℃F (982 degree) rau intermittent kev pab cuam.
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;
