  Small square cans,drawn fish cans (oval), comed beef
cans, ring caps, and other requiring moderate-deep
drawing.

T2.5
52 - 58
  Crowns,top plugs for paint cans, and other applications
where moderate-deep drawability and hardness are
required.

54 - 60
  5-gallon oil can bodies, sundry cans, large cans, and
other applicatons requiring a proper degree of hardness.
 
T4-CA*1
58 - 64
  Can ends and bodies where comparatively high strength
is required.
 
T5-CA*1
62 - 68
  Can ends and bodies where a combination of high
hardness, strength and good formability is desired.
 
Double
Reduced
 
DR8*2
70 - 76
  Bodies and ends for small-diameter cans requiring
high strength.
 
DR9*2
73 - 79
  Bodies and ends for large-diameter cans requiring high
strength.
 
 

Notes:

*1 . The suffix CA means Continuous - Annealing.
*2 . DR: Base metal produced by the double cold reduction process; offers greater
rigidity and strength than conventional base metal and, consequently,provides
the same strength in lighter sections.
