A387 Gr12 Cl2 Hlau Phaj rau Muaj Boilers
A387 Qib 12 Chav Kawm 2nkoj phajyog tsim rau cov kev pab kub kub vim nws cov tshuaj muaj pes tsawg leeg. Nws yog chromium-molybdenum- carbon alloy hlau uas tau siv dav hauv cov hlab ntsha uas tuaj yeem siv tau.
Cov khoom zoo ntawm A387 Gr12 Cl2boiler phajthaum kub kub ua rau nws zoo tagnrho rau industrial boilers. Cov chromium nyob rau hauv cov tshuaj muaj pes tsawg leeg pab txhim kho corrosion thiab oxidation kuj. Vim tag nrho cov khoom no, cov khoom siv yog qhov zoo tagnrho rau kev pabcuam qaub rau hauv ntau qhov kev lag luam.
