■Differences between SUS410 and stainless steel (XM7, 304).

SUS410 is hardened by quenching, making it a commonly used material for general-purpose drill screws.
On the other hand, it has lower corrosion resistance and stronger magnetic properties.
SUS304 is one of the most widely used grades among stainless steels, particularly as a heat-resistant steel.
It is known for its excellent corrosion resistance, weldability, and mechanical properties.
