Tin Coating Thickness

Description

The STM- provides accurate tin coating thickness (tin plating analysis) using the Windows' operating system. It is a computerized coulometric metal thickness gauge for tin plated steel.
The system uses new electrolytic/coulometric hardware and software. These coulometer cells are used by the STM- to inspect the tinplate samples and perform thickness measurement testing on the tin plated ferrum.

The operator inserts the metal sample (strip, or actual sample ' coated with tin) into the cell. Electrolytic fluid fills the cell and the cell is closed. Next, the measurement process can proceed, with top only, top & bottom or 3x top and bottom measurements. Profiles are presented for each of the tin plate steel measurements.

Type of Steel

It contains few residual minor constituents and has good corrosion resistance.
It is widely used for the applications of containers.

It contains particularly few residual minor constituents as Cu, Ni, Cr, Mn.
It is suitable for the materials of containers requiring improved corrosion resistance.

It is an aluminum killed steel.
It is suitable for the applications, that bear deep drawing or other workings which may produce Luder's lines patterns.

Note 1:

Double reduced product is only supplied as stone finish.

Note 2: Sub-classfied based on the surface finishing of the blackplate.

Note 3: The appearance is governed by:
a) the surface characteristics of the steel base which principally result from controlled preparation of the work rolls used during the final stages of temper rolling;
b) the mass of the coating applied; and
c) whether the tin layer is flow-melted or unflow-melted.
