PRODUCT DETAILS

DX53D/SGCD2/SGCD3 Galvanized Coil Description

DX53D (according to European standard EN 10346) and its equivalents SGCD2/SGCD3 (according to Japanese standard JIS G 3302) represent the highest grades of formability in hot-dip galvanized steel coils.

Specifically designed for severe and complex cold forming operations, such as deep drawing, stretch forming, and intricate stamping, these grades feature:

Exceptionally low yield strength and high elongation.

Excellent plastic strain ratio (r-value) and strain hardening exponent (n-value) for uniform deformation.

A consistent microstructure, typically from an aluminum-killed steel substrate, to prevent yielding issues during forming.

The zinc coating provides reliable sacrificial corrosion protection while maintaining the substrate's superior forming characteristics.

Scope of Application

Automotive Deep-Drawn Parts: Fuel tanks, oil pans, complex structural brackets, and inner door panels.

Advanced Appliance Components: Deep-drawn washing machine tubs, sink bowls, and complex outer shells.

Electrical Industry: Precision-formed electrical housings and connector parts.

Construction & Furniture: Complex formed profiles and fittings that require high deformation without failure.


Scope of Application

Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.
