Type of Steel   
MR It contains few residual minor constituents and has good corrosion resistance.
It is widely used for the applications of containers.
L It contains particularly few residual minor constituents as Cu, Ni, Cr, Mn.
It is suitable for the materials of containers requiring improved corrosion resistance.
D 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.

Surface finish

Ra (μm)
Bright smooth Tinplate Yes ≤ 0.35 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.
