Introduction

Tinplate is a thin steel sheet coated by tin. It has a beautiful metallic luster as well as

excellent properties in corrosion resistance, solderability, and weldability. Tinplate is used

for making all types of containers such as food cans, beverage cans, and artistic cans etc. Its

applications are extended for making electrical machinery parts and many other products.

Our tinplate products are manufactured under the ISO9001-based integral quality

management system. Every step from materials sourcing to final finishing processes is

designed to focus on product quality. OS STEEL places utmost emphasis on the product

quality and competitive pricings in order to meet customer requirements. OS STEEL seeks

your continued patronage.

Features and Coating Structure

Characterised by its shiny and beautiful metallic luster. Tinplate

products with various types of surface roughness are produced by

selecting the surface finish of the substrate steel sheet.

Appearance

It has superior painting adhesion properties. Printing is easily and

beautifully finished using various lacquers and inks.

Paintability &

Printability

Through the selection of the correct temper grade, appropriate

formability is obtained for various applications as well as the

required strength after forming.

Formability &

Strength

Excellent corrosion resistance after painting. By selecting the proper

coating weight, the correct resistances against rust, acid, alkali are

obtained.

Corrosion

Resistance

Widely used for making various types of cans by soldering or

welding.

Steel Types of Tinplate

Steel Type

Code Characteristics

MR It contains few residual minor constituents which provides good

corrosion resistance.

L It contains higher concentrations of residual minor constituents

such as Cu, Ni, Cr, Mo, for improved corrosion resistance

R

It is aluminium steel which is suitable for application uses which

bear deep drawing or other working that is liable to produce

Lude’s line.

Manufacturing Process of Tinplate

Electro Cleaning & Pickling

Oil traces on the steel sheet are removed through the physical

force of gas produced by electrolysis of water and the chemical

reaction of caustic soda. Any rust is removed through pickling.

Electro Tin Plating

The vertical cells in operations will be determined by the

coating weight. Equal plating and differential plating are

possible.

Reflow

Electro tin plated coil is heated up to the melting point of tin

and then cooled down by quenching, to give luster to the

product.

Chromate Treatment

Chromate will be treated by electrolytic or non-electrolytic

method, with the plating range from 1~15§·/m².

Oiling

An electrostatic oiler, which uses electromagnetic force to oil

the plates. The range of oiling is 1~20§·/m².

Specification and Sizes

Tinplate can be produced according to standards of JIS G 3303, GB2520-88, and DIN

EN10203-91. This standard specifies two types of cold-rolled tin plates, single-rolled plates

and double-rolled plates. Single cold-rolled tinplates are made of carbon steel with nominal

thickness of 0.15mm to 0.60mm.

Roughness Features & Applications

Bright 0.25 Bright finish for general use.

Stone 0.40 Surface finish with stone marks which 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).

Temper Classifications of Tinplate

The temper designation gives a guide to the hardness (and stiffness) of tinplate products.

For single reduced products, the softer tempers are normally produced from Batch

Annealed (BA) feed, while the harder tempers are offered only from Continuous Annealed

(CA) feed.

Continuous Annealed (CA) products normally have more consistent mechanical properties

throughout the length of coil than Batch Annealed (BA), due to the nature of the process

involved.

T1 BA: Has excellent deep-drawing, anti-aging, mini-earing characteristics. Due to its superb ductility, It is used to make aerosol tops, food can tops, and portable gas containers.

T2 BA/T2.5 BA: It is used to make battery bodies, small tube bodies and lids, and D&I cans.

T3 BA: Has a fine finish and excellent workability. Proper stiffness to prevent buckling. It is used to make bodies and lids of general cans by light drawing.

T4 CA: Has fine finish and excellent strength, perfect characteristics for making cans for carbonated beverages.

T5 CA: Has outstanding cold rolling strength and is used as a substitute for T4 to lower the gauge
