Dab tsi yog s30408 steel?
S30408 steel yog ib hom stainless hlau uas yog tus300 seriesCov. tus tswvzoo heev corrosionUa tsaug rau nws cov ntsiab lus chromium cov ntsiab lus, ua rau nws zoo tagnrho rau cov ntawv thov xws li cov khoom siv hluav taws xob, cov tog tog thiab tso pa tawm. Tsis tas li ntawd, nws muaj zooWeldability thiab Formability, ua koj txoj haujlwm yooj yim dua. Nws cov yam ntxwv zoo kuj tseem ceeb, nrog apaib muaj zog ntawm 205 mpathiab ibLub zog tensile ntawm 520-680 MPACov.
Dab tsi yog 304 stainless hlau?
Suav hais tias tus qauv stainless hlau"18/8", 304 steel muaj kwv yees li18% chromium thiab 8% npib tsib xee, muaj feem ntau ntawm cov hlau, chromium thiab npib tsib xee. Ua achromium oxide tiv thaiv txheejNyob rau saum npoo uas txwv tsis pub oxidation, ua cov ntaub ntawv zoo xws li cov cuab yeej siv, khoom noj thiab dej haus hauv tsev, cov khoom lag luam lag luam thiab khoom siv kho tshuab.

Corrosion Kuj
S30408 muaj ame ntsis siab dua corrosionrau 304, feem ntau yog vim nwsTxo cov ntsiab lus roj(txo cov kev pheej hmoo ntawm kev sib txuam ntawm kev txhim kho corrosion tom qab vuam) thiab los ntawmZoo Dua Chromium Cov Ntsiab Lus, uas txhim kho kev ruaj ntseg ntawm nws txheej tiv thaiv passive. Qhov no muab antau dua ruaj khov thiab tiv thaiv, tshwj xeeb tshaj yog nyob rau hauv welded lossis qhov ntsuas kub.
Yog s30408 thiab 304 sib nqus?
Tsis yog, ob qho tib siTsis yog-hlau tsis muaj austenic stainless hlauNyob rau hauv annealed xeev vim nws lub ntsej muag-nruab nrab cubic crystalline qauv. Txawm li cas los xij, kev ua haujlwm txias heev, xws li khoov lossis tawv nqaij tawv lossis muaj kev cuam tshuam hnyav, tej zaum yuav ua rau kev hloov me ntsis rauMARTENSITE LOS YOG HLAV FRERRITITE, uas ua rau aMagnetism tsis muaj zogCov.
