2. 304L stainless hlau. Yuav kom daws tau qhov teeb meem ntawm kev txhim kho ntawm ultra-low carbon austenitic stainless hlau vim nag lossis daus ntawm Cr23C6 ua rau muaj kev cuam tshuam loj heev ntawm 304 stainless hlau nyob rau hauv qee qhov xwm txheej, nws lub xeev sensitized intergranular corrosion kuj zoo dua li ntawm 304 stainless. hlau. Tsuas yog lub zog qis me ntsis, lwm yam khoom yog tib yam li 321 stainless hlau. Nws yog tsuas yog siv rau cov khoom siv corrosion-resistant thiab cov khoom uas tsis tuaj yeem raug kho tom qab vuam, thiab tuaj yeem siv los tsim ntau lub cev ntsuas.

3. 304H stainless hlau. Cov ceg sab hauv ntawm 304 stainless hlau muaj cov pa roj carbon ntau ntawm 0.04% -0.10%, thiab nws qhov kub thiab txias ua haujlwm zoo dua li ntawm 304 stainless hlau.

4. 316 stainless hlau. Ntxiv molybdenum rau lub hauv paus ntawm 10Cr18Ni12 steel ua rau cov hlau muaj kev tiv thaiv zoo los txo qhov nruab nrab thiab pitting corrosion. Hauv dej hiav txwv thiab lwm yam xov xwm, qhov kev tiv thaiv corrosion yog zoo dua li 304 stainless hlau, feem ntau yog siv rau pitting-resistant cov ntaub ntawv.

5. 316L stainless hlau. Ultra-tsawg carbon steel muaj kev ua haujlwm zoo rau sensitized intergranular corrosion thiab tsim nyog rau kev tsim cov khoom siv welded thiab cov khoom siv nrog tuab ntu qhov ntev, xws li cov khoom siv tiv thaiv corrosion hauv cov khoom siv petrochemical.

6. 316H stainless hlau. Cov ceg sab hauv ntawm 316 stainless hlau muaj cov pa roj carbon ntau ntawm 0.04% -0.10%, thiab nws qhov kub siab ua haujlwm zoo dua li ntawm 316 stainless hlau.
