Qhov sib txawv ntawm Stainless Hlau Yeeb Nkab Thiab Carbon Steel Yeeb Nkab

Nyob rau hauv kev ua lag luam, tib neeg feem ntau confuse carbon steel kav thiab stainless hlau kav. Qhov tseeb, muaj ntau qhov sib txawv ntawm cov kav hlau tsis muaj steel thiab carbon steel kav. Tej zaum koj "tsis tau xav" tias muaj qhov sib txawv ntawm cov kav hlau tsis muaj steel thiab cov kav dej carbon steel.
1. Composition: Stainless hlau yeeb nkab yog ib hom nickel-chromium hlau. Ntxiv nrog rau cov pa roj carbon thiab hlau, kuj tseem muaj cov khoom xws li nickel, chromium, manganese, thiab tooj liab. Carbon steel kav kuj hu ua carbon steel kav. Feem ntau, cov pa roj carbon steel kav yog ua los ntawm kub-kuav los yog txias-kuav los tiag cov pa roj carbon steel los yog low-alloy structural steels xws li 16Mn thiab 5MnV los yog alloy steels xws li 40Cr, 30CrMnSi, 45Mn2, thiab 40MnB.
2. Corrosion kev ua tau zoo: Stainless hlau kav muaj chromium thiab nickel ntsiab. Ob lub ntsiab lus no cuam tshuam nrog cov pa oxygen hauv huab cua los tsim cov yeeb yaj kiab oxide, yog li tiv thaiv cov yeeb nkab los ntawm corrosion. Yog li ntawd, stainless hlau kav muaj zoo corrosion kuj. . Carbon steel kav yog yooj yim rau xeb.
3. Qhov saum npoo ntawm cov kav hlau stainless tuaj yeem ua tiav ntau txoj hauv kev, thiab tuaj yeem ua rau hauv daim iav saum npoo, ci ntsa iab, txhuam nto, thiab lwm yam. Yog li ntawd, cov kav hlau stainless feem ntau yog siv rau cov kav dej zoo nkauj, cov kav dej prop, thiab cov kav dej. Tab sis cov pa roj carbon steel kav feem ntau yog siv hauv kev lag luam.
4. Tus nqi ntawm cov kav hlau tsis muaj steel yog kim dua li cov pa roj carbon steel kav.
