DX54D+AS120 / AS80

DX54D+AS80 and DX54D+AS120 share the same excellent deep-drawing performance, heat resistance, and formability because they use the same DX54D steel substrate. The main difference is the coating weight. AS80 is a cost-effective choice for general industrial and automotive applications, while AS120 provides enhanced corrosion resistance and longer service life for exhaust systems, outdoor equipment, and high-temperature environments.

Product Details

DX54D+AS120 and DX54D+AS80 are aluminized steel grades produced according to EN 10346. Both use the same DX54D extra deep drawing steel substrate, while the difference lies in the aluminum-silicon coating weight. The higher coating weight of AS120 provides better corrosion protection and longer service life, while AS80 offers a more economical solution for general applications.

Understanding the Designation

Grade	Description
DX54D	Extra deep drawing steel
AS	Aluminum-Silicon coating
AS80	80 g/m² total coating weight (both sides)
AS120	120 g/m² total coating weight (both sides)

Since both grades use the same steel substrate, their mechanical properties are nearly identical.

DX54D+AS120 vs DX54D+AS80

Property	DX54D+AS80	DX54D+AS120
Steel Grade	DX54D	DX54D
Formability	Excellent	Excellent
Deep Drawing Performance	Excellent	Excellent
Coating Weight	80 g/m²	120 g/m²
Corrosion Resistance	Very Good	Excellent
Heat Resistance	Excellent	Excellent
Surface Protection	Good	Better
Service Life	Long	Longer
Material Weight	Slightly Lower	Slightly Higher
Cost Efficiency	Higher	Moderate

Mechanical Properties

Since both products use the same DX54D substrate, typical mechanical properties are essentially the same.

Property	Typical Value
Yield Strength	120–260 MPa
Tensile Strength	270–400 MPa
Elongation	≥ 36%
Formability	Excellent
Deep Drawing Capability	Outstanding

The coating weight does not significantly affect strength or formability.

Corrosion Resistance Comparison

DX54D+AS80

Suitable for:

Indoor equipment
Automotive heat shields
Industrial housings
Ventilation systems

Provides good protection in normal atmospheric environments.

DX54D+AS120

Recommended for:

Automotive exhaust components
Industrial furnace parts
Outdoor equipment
High-humidity environments

The thicker coating offers improved long-term corrosion protection.

Heat Resistance Comparison

Characteristic	AS80	AS120
High Temperature Oxidation Resistance	Excellent	Excellent
Exhaust System Suitability	Excellent	Excellent
Thermal Stability	Excellent	Excellent

Because both use the same aluminum-silicon coating composition, heat resistance remains very similar.

Typical Thickness Range

Thickness	Available with AS80	Available with AS120
0.40–1.00 mm	Yes	Yes
1.00–2.00 mm	Yes	Yes
2.00–3.00 mm	Yes	Yes

Both coating options can be supplied in coil, sheet, or cut-to-length formats.
