Notes: 1. The tensile test specified value in the table is suitable for longitudinal test piece.
            2. Tensile test uses sample of L0=50mm, b=25mm, namely P14 sample in GB/T228.

            3. Steel strip is delivered in the state of hot rolling.

Application and characteristics

Ordinary use

TDC51D+Z(ZF)

GB/T 12754-2006

Ordinary use

For stamping

TDC52D+Z(ZF)

For mechanical seaming, and deep punching. Coating and welding performances of alloying hot galvanizing are better.

For structure

TS250GD+Z (ZF)

Used for structure. Good corrosion resistance and processability.
