ASTM B166 for Inconel 600 Bars
ASTM B166 covers Inconel 600 bars, rods, and wires. This standard tells you how to check the quality of each bar. You will find that ASTM B166 asks for many tests. These tests make sure the bar will not fail when you use it.
Here are some of the main quality control measures for Inconel 600 bars:
| Test Type | Tests Included |
|---|---|
| Inspection Procedures | Flattening test, Flaring test, Hardness test, Chemical analysis, Resistance test, Strength test, Durability test |
| Primary Tests | Micro and macro test, Ultrasonic test, Intergranular corrosion test, Radiographic test, Chemical test, Pitting corrosion test |
| Secondary Tests | Positive material test, Mechanical test, Hardness test, Tensile test, Flaring test, Flattening test, Thermal stability analysis |
You can see that ASTM B166 checks for strength, hardness, and corrosion resistance. These tests help you know that the bar will last in tough places.
ASTM B168 for Inconel 600 Plates
ASTM B168 is the standard for Inconel 600 plate, sheet, and strip. This standard tells you how to test and inspect each plate. You will find that ASTM B168 also uses many tests to check the quality.
Here is a list of typical inspection and testing methods for both ASTM B166 and B168:
| Inspection Certificate | Tests |
|---|---|
| EN 10204 Type 3.1 (Mill Test Certificate) | Chemical analysis |
| EN 10204 Type 3.2 (3rd Party Inspection) | Tensile test |
| N/A | Flattening test |
| N/A | Flange test |
| N/A | Nondestructive testing (NDT) |
These tests make sure each plate meets the right chemical and mechanical properties. You can use these results to check if the plate is safe for your job.
Main Differences Between Bar and Plate Standards
- ASTM B166 is for bars, rods, and wires. ASTM B168 is for plates, sheets, and strips.
- Bar standards focus more on shape and strength. Plate standards focus on thickness and flatness.
- Both standards require chemical and mechanical tests, but the test methods may change based on the product form.
Note: ASTM B166/B168 help you get products that meet strict rules. These standards make sure you receive Inconel 600 that works well in high heat and tough environments.
When you follow ASTM B166/B168, you know your Inconel 600 plate or bar will meet the needs of your project. These standards give you confidence in the quality and safety of your materials.
Inconel 600 Plate and Bar Properties
Inconel 600 Chemical Composition (UNS N06600)
You need to know what makes up inconel 600 plate and bar. The chemical composition decides how the nickel alloy performs in tough places. ASTM B166 and B168 set strict rules for the elements in n06600. You will find that nickel is the main part of this alloy. Chromium and iron also play important roles.
Here is a table showing the chemical composition for n06600:
| Element | Composition (%) |
|---|---|
| Ni + Co | 72.0 min |
| Cr | 14.0–17.0 |
| Fe | 6.0–10.0 |
| C | 0.15 max |
| Mn | 1.00 max |
| S | 0.015 max |
| Si | 0.50 max |
| Cu | 0.50 max |
You see that nickel makes up most of the alloy. Chromium helps with corrosion resistance. Iron adds strength. The low amounts of carbon, manganese, sulfur, silicon, and copper help keep the nickel alloy stable.

Nickel content in n06600 must be at least 72%. Chromium ranges from 14% to 17%. Iron stays between 6% and 10%. These limits make sure inconel 600 plate and inconel 600 cold-rolled sheet have the right properties for your needs.
Tip: The high nickel content gives inconel 600 cold-rolled strip and inconel 600 hot-rolled plate their toughness and ability to resist heat.
Inconel 600 Mechanical Properties
You want your nickel alloy to stay strong when things get hot or rough. ASTM B166 and B168 set rules for mechanical properties like tensile strength and yield strength. These rules help you pick the right inconel 600 materials furnished in hard condition for your job.
Here is a table showing the mechanical properties for n06600:
| Property | Minimum Value (MPa) |
|---|---|
| Tensile Strength | 585 |
| Yield Strength | 240 |
| Elongation | 30 |
Tensile strength tells you how much force the nickel alloy can handle before it breaks. Yield strength shows when the material starts to bend. Elongation means how much the alloy can stretch before it snaps.
You can compare inconel 600 to other nickel alloys like inconel 625. Here is a table to help you see the difference:
| Property | Inconel 600 | Inconel 625 |
|---|---|---|
| Yield Strength (MPa) | 310 | 517 |
| Ultimate Tensile Strength (MPa) | 655 | 930 |
| Elongation (%) | 40 | 42.5 |

You see that inconel 600 has lower yield and tensile strength than inconel 625, but it still works well in many places. The high nickel content keeps n06600 tough and flexible.
Note: Inconel 600 plate and bar keep their strength even when you use them in high heat or harsh chemicals.
Why These Properties Matter
You need inconel 600 plate and bar for places with high temperatures and strong chemicals. The nickel alloy resists corrosion and stays strong from very cold to very hot. You can use n06600 in places like nuclear power plants, chemical factories, and food processing.
Here are some reasons why these properties help you:
- The chromium forms a protective layer, so the nickel alloy resists oxidation.
- The alloy keeps its strength up to 2000°F, so you can use it in hot places.
- Nickel gives n06600 ductility and toughness, so it does not crack under stress.
- You get longer life and less risk of failure in critical jobs.
Inconel 600 is a top choice when you need a nickel alloy that stands up to heat and corrosion. You can trust inconel 600 plate, inconel 600 cold-rolled sheet, and inconel 600 cold-rolled strip to perform in tough environments.
