What is AZ150 material
Xi'an Dongmeng Steel Co., Ltd.,
1. What is AZ150 material?
AZ150 is a designation for a hot-dip galvanized coating applied to steel sheet.
A stands for the coating type:
Z stands for the coating process
150 indicates the total minimum coating mass on both sides of the steel sheet: 150 grams per square meter (g/m²)
2. What is Dx51d AZ150 material?
This combines two specifications defined in EN 10346:
Dx51D:Specifies the steel substrate grade.
`D` = Steel for cold forming.
`x` = Non-alloy steel (with specified mechanical properties).
`51` = Minimum yield strength typically around 140-300 MPa (specific range depends on thickness).
`D` = Quality class (Ductility for deep drawing applications).
AZ150: Specifies the coating (Pure Zinc coating, hot-dip, total min. 150 g/m²).
Meaning: "Dx51d AZ150" means steel sheet suitable for deep drawing/cold forming, coated on both sides with a minimum total of 150 g/m² of pure zinc via hot-dip galvanizing.
3. What is the difference between AZ100 and AZ150?
The only difference is the minimum coating mass:
AZ100:Minimum total coating mass = 100 g/m².
AZ150:Minimum total coating mass = 150 g/m².
Consequence: AZ150 provides significantly more zinc and therefore offers better corrosion protection than AZ100. AZ150 is typically used in more corrosive environments where longer service life is required.
4. How thick is AZ150 coating in microns?
The coating thickness is derived from the mass (150 g/m² total) and the density of zinc (7.14 g/cm³).
Minimum Average Thickness per side (typical):Approximately 10.5 microns (calculated as (150 g/m² / 2 sides) / 7.14 g/cm³ = 75 / 7.14 ≈ 10.5 µm per side).
Total Minimum Average Thickness:Approximately 21 microns.
Typical Range:In practice, the actual average coating thickness for AZ150 material often falls within the range of 20 to 25 microns total (10-12.5 µm per side). The minimum local thickness on each side will be less than the average per side value.
5. How to calculate zinc coating thickness?
You calculate the average thickness based on the coating mass and the density of zinc.
Formula:
`Thickness (microns, µm) = [Coating Mass (g/m²)] / [Density of Zinc (g/cm³)]`
Steps:
1. Identify Coating Mass: This is the "AZ" number (e.g., 100, 150). This is the total mass for both sides.
2. Mass Per Side (Optional but common): Divide the total mass by 2 if you want thickness per side. (e.g., AZ150: 150 g/m² total / 2 = 75 g/m² per side).
3. Use Density:Density of pure zinc = 7.14 grams per cubic centimeter (g/cm³).
4. Unit Conversion: Convert g/cm³ to g/m³ for consistency with m² in mass: 7.14 g/cm³ = 7,140,000 g/m³. Alternatively, convert microns directly:
1 micron (µm) = 10⁻⁶ meters (m)
1 g/m² mass spread over 1 m² area with a density of 7.14 g/cm³ gives a thickness in meters = Mass / (Density * Area) = 1 g/m² / (7,140,000 g/m³) = 1.4 x 10⁻⁷ m.
Convert meters to microns: 1.4 x 10⁻⁷ m * 1,000,000 µm/m = 0.14 µm per g/m² per side.
5. Calculate:
Total Average Thickness (µm) = Total Coating Mass (g/m²) x 0.14
Average Thickness Per Side (µm) = (Total Coating Mass (g/m²) / 2) x 0.14 = Total Coating Mass (g/m²) x 0.07
Examples:
AZ150 Total Thickness:150 g/m² * 0.14 µm/(g/m²) = 21 µm
AZ150 Per Side Thickness: (150 g/m² / 2) * 0.14 µm/(g/m²) = 75 * 0.14 = 10.5 µm OR 150 g/m² * 0.07 µm/(g/m²) = 10.5 µm
AZ100 Total Thickness: 100 g/m² * 0.14 = 14 µm
AZ100 Per Side Thickness: 100 g/m² * 0.07 = 7 µm
