321 yog titanium stabilized chromium-nickel austenitic stainless hlau nrog lub zog zoo thiab zoo heev corrosion kuj, raws li muab nyob rau hauv lub annealed mob nrog ib tug raug brinell hardness ntawm 175.Characterised los ntawm siab corrosion kuj nyob rau hauv dav atmospheric corrosive ib puag ncig nws exhibits zoo heev tsis kam mus rau feem ntau oxidizing. Cov neeg ua hauj lwm, cov khoom noj khoom haus, cov tshuaj sterilizing, dyestuffs, feem ntau cov organic chemicals ntxiv rau ntau yam inorganic chemicals, kuj kub roj av gases, chav combustion gases, nitric acid, thiab ib tug tsawg dua sulfuric acid.Nws qhia tau zoo oxidation tsis kam ntawm qhov kub thiab txias muaj kev tiv thaiv zoo rau intergranular corrosion thiab muaj weldability zoo heev.321 tsis tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov, tab sis lub zog thiab tawv tuaj yeem nce ntxiv los ntawm kev ua haujlwm txias, nrog rau kev txo qis hauv ductility.
321 stainless hlau tshuaj muaj pes tsawg leeg
Siv dav rau cov ntawv thov uas qhov sib ntxiv ntawm titanium thiab nws cov nyhuv stabilizing raws li cov carbide tsim cov khoom tso cai rau nws yuav tsum tau welded thiab / los yog siv nyob rau hauv lub carbide nag lossis daus ntau 430oIb-870oC tsis muaj kev pheej hmoo ntawm intergranular corrosion.Cov no suav nrog kev ua zaub mov, khoom siv mis nyuj, tshuaj lom neeg, Petrochemical, Thauj thiab lwm yam lag luam.
321 stainless hlau tshuaj muaj pes tsawg leeg
Cov khoom tsis sib nqus nyob rau hauv cov mob annealed, tab sis tuaj yeem ua cov hlau nplaum me me tom qab ua haujlwm hnyav.
Annealing yuav tsum tau kho yog tias tsim nyog.
