EN 10203 TH415 Cold Rolled Steel Band – High-Quality, Corrosion-Resistant

TH 415 is a single cold rolled band (black plate in coils) of soft unalloyed steel and in the surface qualities plain, stone finish and matt for conventional packaging sheet. The band is produced in thicknesses of 0,17 to 0,49 mm in steps of 0,005 mm. The surface is oiled in order to avoid corrosion. The strip is applicated for the production of - electrolytically tinned tinplate Tin used for coating has to show a purity grade of 99,85%. Preferred tin plating values (double-sided) are: 1,0 1,4 2,0 2,8 4,0 5,0 5,6 8,4 11,2 14,0 15,1 g/m² Tinplate is also delivered diferentially coated. In this case is necessary a special designation . Appearance of the tinplate surface is determined by the surface characteristics of the basic material and type of tincoating. Available surface qualities: bright, stone finish, silver matt and matt - electrolytically special chromed steel (ECCS) Total Cr-content used for coating consists of metallic chromium and chromium oxides. The mean coating weight of metallic chromium accounts for 50 to 140 mg/m² and 7 to 35 mg/m² for chromium oxides. Surface appearance of ECCS which follows from the application of work rolls of a special surface texture during the last cold rerolling steps is determined by the surface characteristics of the basic material. Available surface qualities: matt, plain, stone finish For the choice of surface refined extra-fine sheets has to be considered the final consumption purpose, e.g. requirements, such as suitability for punching, drawing, folding, beading, welding and soldering. Application of extra-fine sheets: - cans, jugs, canister, buckets - household articles, boxes, closures - ceiling elements, fittings, pressure plates etc.
