Product Description

304 Stainless Steel Metal Sheet SUS304 Metal Sheet

High-quality 304 stainless steel sheets manufactured to ASTM A240 standards with various surface finishes for diverse industrial applications.

Surface Treatments and Characteristics

Surface Finish	Characteristics and Application
NO.2B	Better surface brightness and flatness than NO.2D. Through special surface treatment to improve mechanical properties, suitable for comprehensive uses.
NO.1	Surface finished by heat treatment and pickling after hot rolling.
NO.4	Polished with abrasive belt of grit #150-#180, better brightness with discontinuous coarse stria, thinner than No3. Used for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment.
HL	Polished with abrasive belt of grit #150-#320 on NO.4 finish with continuous streaks. Mainly used for building ornaments, elevators, building doors, and frontal plates.
BA	Cold rolled, bright annealed and skin-passed. Excellent brightness and good reflexivity like mirror. Used for kitchen apparatus and ornaments.
8K	Excellent brightness and preferred reflexivity, can be used as mirror.

Corrosion Resistance

Stainless steel's resistance to corrosion and staining, low maintenance requirements, and familiar luster make it an ideal material for numerous applications. The alloy is extensively used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and as automotive and construction material in large buildings. It is particularly suitable for commercial kitchens and food processing plants, as it can be steam-cleaned and sterilized without requiring paint or other surface finishes.
