Description
AS150 aluminized steel coil is one of the most widely selected aluminium-silicon coating classes for industrial heat-resistant applications. With a nominal coating mass of 150 g/m², it provides a strong balance between oxidation resistance, coating durability, and manufacturing efficiency.
For automotive exhaust systems, heating equipment, ovens, and high-temperature industrial components, AS150 is often considered a practical standard choice because it delivers reliable protection without requiring the heaviest coating level.
What Does AS150 Mean in Aluminized Steel?
The AS150 designation refers to an aluminium-silicon coating class under the aluminized steel coating system. The number “150” represents the nominal total coating mass on both surfaces.
| Item | AS150 Specification |
|---|---|
| Coating Type | Aluminium-silicon alloy coating |
| Nominal Coating Weight | 150 g/m² total coating mass |
| Approximate Thickness | About 21–25 μm per side |
| Main Feature | High-temperature oxidation protection |
The actual coating thickness depends on production conditions, coating distribution, and measurement location. Therefore, coating mass inspection is normally used for acceptance verification.
Why AS150 Became the Common Industrial Standard
The popularity of AS150 comes from the balance between protection performance and practical manufacturing requirements. A lighter coating may reduce protection time, while a heavier coating increases material consumption and may not provide additional value for normal service conditions.
• Suitable for continuous heat exposure environments
• Strong resistance against oxidation
• Good coating stability during forming
• Balanced choice for large-volume industrial production
In many exhaust and heating applications, the operating temperature can approach around 600–700°C. AS150 provides sufficient aluminium protection for these environments while maintaining good processability.
Typical Applications of AS150 Aluminized Steel
AS150 is widely used where steel components must resist repeated heating cycles and oxidation.
| Application | Why AS150 Is Selected |
|---|---|
| Automotive exhaust mufflers | Protects against high-temperature oxidation |
| Catalytic converter shells | Maintains durability under heat cycles |
| Boiler components | Improves oxidation resistance |
| Oven and grill parts | Provides heat-resistant surface protection |
AS150 vs AS120 vs AS200 Comparison
Different coating classes are selected according to temperature exposure, service life requirements, and environmental severity.
| Coating Class | Approx. Thickness | Protection Level | Typical Selection |
|---|---|---|---|
| AS120 | 17–20 μm/side | Balanced protection | General industrial components |
| AS150 | 21–25 μm/side | Standard high protection | Exhaust and heating systems |
| AS200 | Higher than AS150 | Heavy-duty protection | Severe environments |
AS150 Coating Uniformity and Edge Effect
During continuous coating production, coating distribution must be carefully controlled. One common inspection point is the edge effect, where coating thickness near the strip edge may differ from the center area.
For critical applications, buyers should confirm:
- Coating weight test results
- Thickness measurement positions
- Surface condition across the coil width
- Coating adhesion after forming
A visually smooth surface does not always guarantee uniform coating weight, so technical inspection documents are important for industrial purchasing.
