IDENTIFICATION DATA OF THE TIN
 OPERATION Quality
 Base steelMC = Low resistance to corrosion
MR = The most common.Good resistance to
corrosion
L = High resistance to corrosion
D = Calmed to aluminum. Stuffing
deep
 Thickness of the metal In 1/100 mm.
 Rolling techniqueSD = Simple reduction
DR = Double reduction
EH = Cold humid
 Annealing BA = Base or bell
CA = Continuous
Quenching T 73 (example) = Hardness (Simple reduction)
DR 550 = Elastic limit (Double reduction)
Surface finish Sparkly
Mate
Stone

 Width of the bobbin (or sheet) In mm. (-0 +3)
 Esatañado (Chromado) Tinned = 2.8
Tinned differential = 2.8 / 5.6
Chromed = 0.1-0.1
 Tin remelting
(tin-iron alloy)
 No K
Type K = Longer life – Good resistance to products that
they provoke a rapid unseat.
 Passivation300 = Chemical (CrO) – Unstable – Good varnish adhesion
(sausages) – Weak protection against sulfuration.
311 = Chemical and electrolytic (CrO + Cr) – Stable – Acceptable
adherence of inks and varnishes -The most common
312 = Electrolytic (Cr) – 311 reinforced – High resistance to
sulfuration – Lower adhesion to varnishes
 OiledD.O.S    = Di-octil-sebacate
A.T.B.C. = Actil-tributil-citrate
B.S.O.   = Butyl-stearate-oil
 Height of the leaf In mm.
R = Straight cut
W = Scroll cut
 Quality1st or standard = No major defects
2nd = It has lighters defetos of aspect and form
3rd = It has important defects
Etc
