DR tinplate is thin, strong material developed as a substitute for ordinary tinplate to meet customer's requirements to reduce tinplate thickness |
|
|
|
Features
|
|
● |
Stifness and strength are greater for same thickness of ordinary tinplate |
|
● |
Reduced thickness make it possible to increase the number of sheets per unit mass, and consequently reduce costs |

|
Code |
Classification |
Features |
|
B |
Bright |
A luster surface provided by a flow-brightened tin coating on a smooth grindstone finish stell base |
|
R |
Stone |
Melted finish. This finish has fine grit lines, and is easy to handle because it resists scratching during coating and can-making |
|
R2 |
Super Stone |
Melted finish. High resistance to scratching, thus making it asily handling during coating and can-making and is widely used for cna ends |
|
M |
Matte |
Unmelted dull finish. This finish gives the tinplate a unique silver gray surface. It oftens exceptional ink adherence and is widely used in crown caps and printed cans |
|
S |
Silver |
A luster surface provided by a flow-brightened tun coating on a coarse dull finished steel base |
|
Note:
|
|
● |
Double reduced product is available in stone and super stone finish only |

Remarks |
|
MR |
Contains low residual elements and has a good corrosion resistance. Commonly used for most tinplate applicaitons |
|
L |
Contain particularly low residual elements such as Cu, Ni, Cr and Mo and is used for improved corrosion resistance of certain food-product containers |
|
D |
Aluminium killed, is sometimes required for severe drawing applications or to minimize severe fluting and stretcher strain hazards |
