Home >> Tin Free Steel

Overview

Tin Free Steel (TFS)  is also called ECCS (Electrolytic Chromium / Chromium Oxide Coated Steel), obtained by coating the metal base (low-carbon steel) with an ultra-thin layer of metallic chrome and then with a chromium oxide layer. TFS offers outstanding corrosion resistance, lacquer adhesion as well as printability.  With all of these featuresTFS widely used for the production of Draw Redraw two-piece cans, seamed cans and many components that do not have to be welded, such as ends, lids, crown corks, twist-off caps and aerosol bottoms and tops.

 

Special Applications

DR TFS

DR- Double Reduced , make DR TFS have higher level of  Rigidity and Strength , with these features, enable thinner DR TFS display an identcial level of durability to the General TFS,  widely used for Twsit off caps , Two- pieces Cans, Can Body etc products, and reduced costs to a large extent. 

Soft TFS

Soft for Temper,  T1 which Rockwell hardness at 49. Clean surface with good property make TFS to be a perfect protective material for optical fiber cables.

Gerneral TFS

TFS play more and more important role in Metal Packing Industry, it's an economical and high quality replacement for tinplate .Lower in price than tin plates, tin free steel boasts superior lacquer and paint adhesion and strong resistance against corrosion. widely used for food and chemical packing industries.
