What are the commonly used metal stamping materials?

1. cold rolled steel plate:

1. Definition: Cold rolling is made of hot-rolled coil as raw material and rolled below recrystallization temperature at normal temperature. Cold-rolled steel plate is a steel plate produced by cold rolling process, referred to as cold plate. The thickness of the cold-rolled plate is generally between 0.1mm and 8.0mm, and the thickness of the cold-rolled steel plate produced by most factories is less than 4.5mm. The thickness and width of the cold-rolled plate are determined according to the equipment capacity and market demand of each factory.

2. Classification:

The SPCC---S is expressed as steel (Steel),P is expressed as plate (Plate),C is cold (Cold), and C is commercial (Commercial), which is the Japanese JIS standard.

SPCD --- means cold-rolled carbon steel sheet and strip for stamping, equivalent to China 08AL(13237) high-quality carbon structural steel.

SPCE --- means cold-rolled carbon steel sheet and strip for deep drawing, equivalent to China 08AL(5213) deep drawing steel.

2. galvanized steel sheet

1. Definition: Galvanized steel sheet is a welded steel sheet with a hot-dip or electro-galvanized layer on the surface

2. Classification:

Electrogalvanized steel (SECC): uniform gray, mainly imported, fingerprint resistant, has excellent corrosion resistance, and maintains the workability of cold rolled plates. Uses: home appliances, computer chassis shell and some door panels and panels.

Hot-dip galvanized steel sheet (SGCC): dip-plated, bright white, small zinc flowers (more difficult to see), large zinc flowers can clearly see hexagonal flower blocks. Only China Steel in Taiwan Province is available in China, and Corporation two factories in Shengyu Steel can produce it. No steel mill in mainland China can produce high-quality materials, mainly relying on imports.

3. Main characteristics: corrosion resistance, paint, formability and spot weldability. It is widely used, mainly for small household appliances that need good appearance parts, but compared with SECC, its price is more expensive, so many manufacturers switch to SECC to save costs.
