Tin Mill Products - U. S. Steel Košice, s.r.o

Application

Black plate – used for production of transport containers, lids, guide signs and for further metal coating.
Electrolytic tinned plate – used for production of food packages, beverage containers, decorative tins, lids, closures, 2 piece cans, 3 piece cans, ends, crown caps, toys and other products.

Quality control system in accordance with international standard ISO 9001, issued by TÜV CERT has been implemented as an effective instrument of high quality production and products.

All steels are produced by modern BOF technology; prescribed chemical composition is strictly maintained and are fully killed steels continuously cast into slabs.

Material is continuously or batch annealed and skin passed (SR sheets) or double reduced (DR sheets). Coils are continuously electrocoated utilizing the patented Ferrostan process.

Tin mill products are provided as wide coil or sheets with tin utilizing the patented Ferrostan process.

Grades

Tin mill products products are classified into grades according to their mechanical properties.
