what is Inconel 600(UNS N06600)?
Inconel 600 (UNS N06600, EN W.Nr 2.4816) is a nickel-chromium-iron alloy (Ni ≥ 72%, Cr 14.0–17.0%, Fe 6.0–10.0%) with excellent resistance to chloride stress-corrosion cracking, high-temperature oxidation and many corrosive media.

Corrected Weight Table (Density 8.47 g/cm³)
Weight per unit area: kg/m² = 8.47 × thickness (mm); lb/ft² = 44.06 × thickness (in.). The values below are calculated from the density and are directly usable for quotation and freight estimation.
| Thickness (mm) | Thickness (in.) | Weight (kg/m²) | Weight (lb/ft²) |
|---|---|---|---|
| 0.5 | 0.020 | 4.2 | 0.87 |
| 1.0 | 0.039 | 8.5 | 1.74 |
| 2.0 | 0.079 | 16.9 | 3.47 |
| 3.0 | 0.118 | 25.4 | 5.21 |
| 4.76 (3/16) | 0.1875 | 40.3 | 8.26 |
| 6.35 (1/4) | 0.250 | 53.8 | 11.02 |
| 9.53 (3/8) | 0.375 | 80.7 | 16.52 |
| 12.7 (1/2) | 0.500 | 107.6 | 22.03 |
| 19.05 (3/4) | 0.750 | 161.4 | 33.05 |
| 25.4 (1) | 1.000 | 215.1 | 44.06 |
| 38.1 (1-1/2) | 1.500 | 322.7 | 66.10 |
| 50.8 (2) | 2.000 | 430.3 | 88.13 |
Example: 10 tons of 12.7 mm plate = 10,000 / 107.6 ≈ 92.9 m² of surface area - use this figure for area-based quotations (cutting, surface treatment, packaging).
Coil / Strip Thickness Tolerances
Thickness tolerance for coil and strip depends on thickness, width and tolerance class. The table below shows a typical mill tolerance pattern for nickel-alloy strip (values in mm); confirm the exact class with your supplier against ASTM B168 or the applicable EN specification before ordering.
| Thickness T (mm) | Width 630–1000 mm | Width 1000–1250 mm | Width 1250–1550 mm |
|---|---|---|---|
| 0.25 ≤ T < 0.40 | ±0.035 | ±0.030 | – |
| 0.40 ≤ T < 0.60 | ±0.035 | ±0.035 | – |
| 0.60 ≤ T < 0.80 | ±0.040 | ±0.040 | – |
| 0.80 ≤ T < 1.00 | ±0.050 | ±0.040 | ±0.050 |
| 1.00 ≤ T < 1.25 | ±0.055 | ±0.050 | ±0.060 |
| 1.25 ≤ T < 1.60 | ±0.060 | ±0.055 | ±0.060 |
| 1.60 ≤ T < 2.00 | ±0.070 | ±0.065 | ±0.080 |

FAQ:
Q1: What thickness range is available for Alloy 600 plate?
Per ASTM B168, plate is 3/16 in. (4.8 mm) and thicker. Typical industry stock covers 3/16 to 2 in; heavier gauges up to 4 in. are on mill order.
Confirm current stock with the supplier.
Q2: How do I convert Alloy 600 plate weight?
Weight = 8.47 x thickness (mm) kg/m2, or 44.06 x thickness (in.) lb/ft. A 1-inch plate ≈ 44.06 lb/ft2 (215.1 kg/m2).
Q3: Is the steel/aluminum gauge chart valid for Alloy 600?
No. Gauge conversion charts describe carbon steel and aluminum sheet practice. Alloy 600 sizes follow ASTM B168 decimal-inch or milmeter
thicknesses.
Q4: What is the difference between plate, sheet and strip?
Plate is 3/16 in. and over 10 in. wide; sheet is under 3/16 in. and 24 in. wide; strip is under 3/16 in and under 24 in. wide.
Q5: Which standards cover Alloy 600 coil and strip?
ASTM B168/ASME SB168 (flat products). ASTM B167 (eamless tube), ASTM B166 (rod/bar. ASTM B564 (forgings). UNS N06600, EN W.Nr2.4816.
