Features 3~6 times better corrosion-resistant compared to GI, but has a similar level of processability and weldability.
Has greater surface hardness than GIs, and is much more wear-resistant.
Corrosion resistance increased more with resin-coating treatment, which enables roll forming
Or press forming without the spraying of processed oils.
