What are the common thickness and width specifications for DX51D coils?

A: Thickness typically ranges from 0.4 to 3.20 mm, with 0.5 mm and 0.8 mm being common. Width generally ranges from 600 to 1250 mm, with 1000 mm and 1250 mm being the mainstream specifications.

What are the common zinc coating weight specifications for DX51D coils?

A: Common double-sided zinc coating weights are 80 g/m², 120 g/m², 150 g/m², 180 g/m², and 275 g/m², with the highest domestic weight reaching 275 g/m², and imported products even exceeding 300 g/m².

What is the approximate zinc coating thickness of a DX51D coil corresponding to a 150 g/m² zinc coating?

A: The weight and thickness of the zinc coating are positively correlated. A zinc coating thickness of 150g/㎡ is approximately 22μm (e.g., 80g/㎡ corresponds to approximately 11μm, and 180g/㎡ corresponds to approximately 27μm).

Which JIS and ASTM standards are equivalent to DX51D coils?

A: DX51D+Z is equivalent to SGCC of JIS G3302 and CS C type of ASTM A653M.

What forming and processing techniques are suitable for DX51D coils?

A: Suitable for cold working processes such as bending, stamping, and shearing. Its low carbon content gives it good plasticity and toughness, making it less prone to zinc coating peeling or steel base cracking during processing.
