Double Reduced Cold-Rolled Tinplate Description

Tinplate is a steel product with a stampable thin steel plate as the base, tin plating on the surface, and multiple protective films. It has the characteristics of corrosion resistance, non-toxic, odorless, glossy surface, light weight, high strength, easy to print, easy to weld and process, as well as a strong adaptability to ambient temperature. Double cold-reduced tinplate is usually supplied with a stone surface finish and a flow-brightened tin coating. When ordering double cold-reduced tinplate, the purpose of manufacture for which the material is intended should be stated. Double reduced cold-rolled tinplate is relatively less ductile than single reduced cold-rolled tinplate and has very distinct directional properties, so for some uses, for example for built-up can bodies, the direction of rolling should be stated.

Surface State of Tinplate

Surface State	Features
Light Surface	Electroplated tin smooth raw material strip after melting treatment to obtain the glaze,Smooth surface with very fine grindstone pattern
Stonetextured Surface	Electroplating tin raw material with the glaze obtained after melting treatment,Grindstone pattern with certain direction
Silvercolor Surface	Electroplating tin raw material with the glazed surface obtained after melting treatment, the surface is rough and dull
Mattless Surface	The surface of the substrate is rough and dull, and the tin plating layer is not soft melting

Substrate Type

Substrate Type	Introduction
MR	The most general steel, steelmaking impurity residue less, excellent mechanical properties and corrosion resistance
L	Used for the production of acidic contents (oranges, yellow peaches, pineapples, etc.), and the inner surface of the food cans for iron high corrosion resistance tinplate substrate steel, such tinplate is often calledKPlate
D	Used to produce two pieces of high-processing tin plate substrate steel, such tin plate is often called.DIMaterial
SPCC	Chinese characteristics, using ordinary hot rollingSPHCProduces, usually used for miscellaneous tank purposes.

Ordering Notes

The ordering elements for tin plating generally include: standard grade (including steel grade code, annealing method and other information such as MR T-3 CA), size (the default order is thickness * width * length, tin plating amount ((different thickness plating) Tin needs to add A/D as the marking line mark, if not, no marking line will be marked), surface, order quantity, etc.
When ordering tin plating, please confirm with our sales staff the end use, such as canbody, ends, twist off caps, crown cork, EOE, etc., as well as the contents, special contents such as milk powder, high protein food, mushrooms, fruits, etc.;
