Application for Temper and Finish

	Temper Grade	Hardness Guarantee HR30T	Applications
Single Reduced	T-1	49 ± 5	Cans, nozzles and other applications involving deep drawing that requires large flexibility.
	T-2	53 ± 5	Items that require moderate drawability and some stiffness.
	T-2.5	55 ± 5	Items that require the drawability of T-2 in combination with the stiffness of T-3. For general use.
	T-3	57 ± 5	Proper stiffness is imparted to prevent buckling. For general use.
	T-S	59 ± 5	Items that require better formability than T-4 (JFE Standard)
	T-4	61 ± 5	Can bodies, ends and crowns that require comparatively large stiffness.
	T-5	65 ± 5	Can bodies, ends and other applications that require excellent buckling resistance.
Double Reduced	DR-8	73 ± 5	Bodies of carbonated beverage cans and beer cans that require stiffness and strength.
	DR-9	76 ± 5	Ends of carbonated beverage cans and beer cans that require stiffness and strength.
	DR-9M	77 ± 5	The same as DR-9.
	DR-10	80 ± 5	Special applications that require strength.

There are two types of annealing : batch annealing and continuous annealing. When continuous annealing is designated, the symbol of "CA" is added after the temper grade symbol such as "T-4CA".
The soft materials (T-1 to T-3) can also be manufactured by continuous annealing. Please consult us.
DR-8, DR-9, and DR-10 are thin materials with high strength manufactured by cold-reducing the materials after cold-reducing and annealing.

Finish	*Surface Roughness Aim Ra ()**	Features & Applications
Bright	0.25	Bright finish for general use.
Stone	0.40	Surface finish with stone marks that make printing and can-making scratches less conspicuous.
Super Stone	0.60	Surface finish with heavy stone marks.
Matte	1.00	Dull finish mainly used for making crowns and DI cans (unmelted finish for tinplate).
Silver (Satin)	-	Rough dull finish mainly used for making artistic cans (tinplate only, melted finish).
