Temper

Single - Reduce Tinplate
Designation Aimed Rockwell Hardness Range 30T Characteristic Application
T - 1 46 - 52 Soft for drawing Nozzles, spouts, toys, and other applications requiring extra deep drawing
T - 2 50 - 56 Moderate drawing where some stiffness is required Rings and plugs, small-deformed cans, and other applications requiring moderately-deep drawing
T - 2.5 52 - 58 Combines the characteristics of T - 2 and T - 3 Battery cells bodies, small can ends, and bodies, and other applications requiring moderately-deep drawing
T - 3 54 - 60 Shallow drawing, general purpose with fair degree of stiffness to minimize fluting Can ends and bodies, large diameter closures, crown caps
T - 4 58 - 64 Moderate stiffness Can ends and bodies where comparatively high strength is required
T - 5 62 - 68 Increased stiffness to resist buckling Can ends and bodies where a combination of high hardness, strength, and good formability is required
 

Double - Reduce Tinplate
Designation Aimed Rockwell Hardness Range 30T Application
DR - 8 68 - 78 Bodies and ends for small diameter cans requiring high strength
DR - 9 71 - 81 Bodies and ends for small diameter cans requiring high strength
DR - 10 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:
  • Stiffness 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 Types
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
