Internal structure composition of tinplate
Tinplate in Italy Market
As is known to all, Italy is rich in tomatoes, and spaghetti and pizza are their specialties, so they need cans to store ketchup and tomato paste.
Tinplate is the most suitable material for producing cans.
So there is a huge demand of tinplate in Italy market.
Coating Mass /Coating weights for tinplate
There are two types coating of mass: the Equally coated Mass(in which both sides have the same mass of tin coating) and
the Differentially Coated Mass(in which one side is more heavily coated than the other )
|Letter symbol of classification||Type of Coating||Designation of |
|Nominal coating |
|Former designation |
|SPTE Tinplate||Equally coating||2.8/2.8||2.8/2.8||2.45/2.45||#25|
Temper of Tinplate
XINO Steel produces tinplate in the following tempers:
|Nominal hardness |
|Yield strength |
|SR||T-1||49||230+/-50||TS230||Soft for drawing||Drawing requirements, drawn ironed cans, nozzles, spouts, closures|
|T-2||53||245+/-50||TS245||Moderate drawing where some stiffness is required||Rings and plugs, dome tops, closures, shallow drawn and specialized can parts|
|T-2.5||55||260+/-50||TS260||Combines the characteristics of T-2 and T-3.||Battery cell bodies, small can ends and bodies|
|T-3||57||275+/-50||TS275||Shallow drawing, general purpose with fair degree of stifness to minimum fluting||Can ends and bodies, large diameter closures,crwon caps|
|T-3.5||59||290+/-50||TS290||Decreased stifness||Can bodies, and closures and crown caps|
|T-4||61||340+/-50||TH415||Moderate stiffness||Can bodies, and closures and crown caps|
|T-5||65||480+/-50||TH435||Increased stifness to resist buckling without the use of rephosphorized steel||Can ends and bodies|
|DR||DR-7.5||71||520+/-50||TH520||Great stifness and strength||Can ends and bodies, drawn-and-redrawn-cans|
Surface / Finishes of Tinplate
Tinplate surface: Bright,Stone,Super Stone,Matt, Silver
Finishes: Bright, fine stone ,stone,silver matte
Different finishes have differently Roughness:
|fine stone||0.25 – 0.45|
|stone||0.30 – 0.75|
|silver matt||0.40 – 2.25|
|matt||0.40 – 2.25|
Steel types/ Grade:
XINO Steel produces tinplate base metal in a broad range of types to meet customers' requirements for corrosion resistance, workability and strength. Chemical compositions are controlled by ladle analysis.
|L||This steel which is low in metalloids and residual elements, us sometimes used for improved internal corrosion resistance for certain food product containers.|
|MR||Similar in metalloid content to Type L but less restrictive in residual elements, is commonly used for most tinplate applications.|
|D||Aluminum killed, is sometimes required for severe drawing applications or to minimize severe fluting and stretcher strain hazards.|

Packing and Marking
XINO STEEL tinplate is packed with special care to withstand severe handling in marine transit. Special care is given to prevent rust and scratching.
Typical examples of packaging methods are shown above.
Each package is marked with product name. Specifications, coating mass, thickness, dimensions, temper, number of sheets contained, met weight, gross weight, production number, package number, origin and “XINO STEEL”. Other marks can be added, if desired.
