Double - Reduce Tinplate

DR - 8

Aimed Rockwell Hardness Range 30T	Application
68 - 78	Bodies and ends for small diameter cans requiring high strength

DR - 9

Aimed Rockwell Hardness Range 30T	Application
71 - 81	Bodies and ends for small diameter cans requiring high strength

DR - 10

Aimed Rockwell Hardness Range 30T	Application
75 - 85	Bodies and ends for small diameter cans requiring high strength

DR tinplate is thin, strong material developed as a substitute for ordinary tinplate to meet customer's requirements to reduce tinplate thickness
Note:
●	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

Finishes

Code / Classification	Features
B / Bright	A luster surface provided by a flow-brightened tin coating on a smooth grindstone finish steel 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 easy to handle 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 offers exceptional ink adherence and is widely used in crown caps and printed cans
S / Silver	A luster surface provided by a flow-brightened tin coating on a coarse dull finished steel base

Note: Double reduced product is available in stone and super stone finish only

Steel Type

Steel Types	Remarks
MR	Contains low residual elements and has good corrosion resistance. Commonly used for most tinplate applications
L	Contains 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
