TFS/ECCS
TFS/ECCS is an electrolytic chrome plated steel consisting of a thin layer of metal chromium and a layer of hydrated chromium oxide deposited on the steel base which gives it a lustrous metallic finish on both surfaces.
TFS / ECCS may be Single Reduced (SR) or Double Reduced (DR) type and available, both in sheet / coil form.
TCIL is certified to produce SR TFS under BIS certification (IS 12591 / ISO 11950). TFS/ECCS (SR/DR) is available in the same range of dimensions/ temper/ mechanical properties and oil film as ETP.
Typical End Uses of TFS / ECCS
TFS / ECCS is used for Crowns and Lug Caps. It is also used for General line cans for various end uses.
