Hardness testing of tinplate

Hardness testing of tinplate is conducted using either the Rockwell or pencil hardness method, which assesses the surface resistance to deformation of the tin-coated steel through steel ball indentation or scratch tests. This is used to control the scratch resistance and forming stability of can packaging materials, ensuring the adhesion of printed coatings and resistance to wear during transportation.
Selection
Select Rockwell HR30T or pencil hardness tester based on product thickness; use H scale for tin coating weight greater than 2.8 g/m², and T scale for thin coatings; use HR30T 68-72 degrees for can bodies, and HR30T 72-76 degrees for lid materials; verify coating uniformity with a film thickness gauge.
