Stainless steel strip size specifications

Thickness: Commonly 0.1mm~6.0mm (ultra-thin strips are used for electronic components, and thick strips are used for structural parts).

Width: Narrow strips (<100mm) are used for precision parts, and wide strips (>1000mm) are used for stamping plates.

Length: Coil (such as 100 meters/coil) or cut to length (such as 6 meters/strip).

Note: Tolerance requirements (such as ±0.02mm) affect processing accuracy and need to be clarified with the supplier.

Surface treatment

Surface type Features Applicable scenarios

2B surface Bright annealing after cold rolling, smooth and reflective General use, such as kitchenware, building materials

BA surface Mirror polishing, high gloss High-end decoration, electronic products

No.4 (brushed) Matt texture, anti-fingerprint Home appliance panels, elevator decoration

Sandblasting/etching Rough or patterned surface Art decoration, signage

Passivation treatment Enhanced corrosion resistance Medical equipment, chemical environment

Mechanical properties

Hardness: Soft state (such as 304-O) is easy to form, and hard state (such as 304-H) is suitable for springs.

Tensile strength: Select according to load requirements (such as 301 can reach more than 1000MPa).

Ductility: Low hardness materials (such as 304-DDQ) are required for deep drawing.
