FerroChrome
Loj:1-100 hli
Ferrochrome (FeCr) yog ib qho alloy ntawm chromium thiab hlau uas muaj nyob nruab nrab ntawm 50% thiab 70% chromium.Ntau tshaj 80% ntawm lub ntiaj teb no ferrochrome yog siv nyob rau hauv zus tau tej cov stainless hlau.Raws li cov ntsiab lus carbon, nws tuaj yeem muab faib ua: Cov pa roj carbon ntau ferrochrome / HCFeCr (C: 4% -8%), Nruab nrab carbon ferrochrome / MCFeCr (C: 1% -4%), Cov pa roj carbon tsawg ferrochrome / LCFeCr (C: 0.25). %-0.5%), Micro carbon ferrochrome / MCFeCr: (C: 0.03 0.15%).Tuam Tshoj rau nce kev faib ua feem ntawm lub ntiaj teb no ferrochrome ntau lawm.

Daim ntawv thov:
①Utilised nyob rau hauv zus tau tej cov stainless hlau,Stainless hlau nyob ntawm chromium rau nws cov tsos thiab tsis kam mus corrosion.
② Raws li lub ntsiab alloy additive nyob rau hauv steelmaking
③Raws li indispensable additive nyob rau hauv tus txheej txheem ntawm tsawg carbon steel smelting
