What P Number Is Inconel 625?

What is Inconel 625 made of?

Inconel 625 is a high-performance nickel-chromium-molybdenum alloy known for its high level of strength, temperature resistance, and corrosion resistance.

This superalloy is composed mainly of nickel (58% min.).

What is the difference between Inconel 600 and 625?

For instance, Inconel 625 has a nickel content between the range of a minimum of 58% and this means that it thus falls in the middle of the 330 and 600 alloys. On the other hand, Alloy 600, has a nickel content of a minimum of 72%. … As compared with other alloys of Inconel, Grade 625 is pretty easy to weld.

Does Inconel work harden?

Starting with a Solutionized Metal Cold-drawing metal hardens the work surface and makes Inconel even harder to work, causing more stress to tooling. Starting with a solutionized piece of Inconel is optimal because it helps to limit the amount of work hardening which reduces the wear on machining tools.

Why is Inconel so expensive?

For one thing, Inconel is much more expensive than stainless steel alloys. Inconel also has much better corrosion resistance and strength at high temperatures. … When deciding between the two different alloys, the main deciding factor is cost, temperature, and strength.

How strong is Inconel?

How Strong is Inconel®? When determining strength, tensile strength, corrosion resistance, and even melt resistance can be measured. Inconel 625® has a high tensile strength range of 103 – 160 ksi compared to the 73.2 ksi of stainless steel and can maintain that strength at higher operating temperatures.

What is s number in welding?

S-Nos. These are the listing of those materials which have been included by ASME B31 code or by selected ASME boiler and pressure vessel code cases but are not included in ASME boiler and pressure vessel code material specifications (ASME Sec. II). Purpose is the same as of P-numbers.

What is Inconel 600 material?

Inconel 600 is a nickel-chromium alloy with good oxidation resistance at higher temperatures, with good resistance in carburizing and chloride containing environments. Inconel 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000 deg F(1093 deg C).

What is the difference between Monel and Inconel?

In the most basic terms INCONEL® is a nickel-chromium alloy whereas MONEL® is a nickel-copper alloy. Both metals are commonly used in applications with extreme heat, high temperature corrosion, and generally severe conditions. … There are various other MONEL® and INCONEL® alloys which may be more suitable to your needs.

What does Inconel look like?

Inconel jewelry looks like stainless steel, but feels more like aluminum in weight.

Does Inconel rust?

What is Inconel? Inconel encompasses a particular set of nickel alloys or nickel-chromium alloys. Inconel alloys are durable, corrosion resistant, rust resistant and very sturdy.

Is Inconel 625 a stainless steel?

What is P number and group number?

P numbers are groupings of base metals with similar welding characteristics that have been approved for pressure boundaries when constructing pressure vessels or piping systems. Group numbers are sub-groupings within a P number that further subdivides the P number.

What is a number in ASME?

1) The A-Number: The A-Number is a calculated value based on a combination of the chemical composition of the weld filler metal (which may be found in ASME Section II Part C), and ASME Section IX’s A-Number Table QW-442.

What does Monel mean?

Monel is a group of nickel alloys, primarily composed of nickel (from 52 to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. (Alloys with copper contents 60% or more are called cupronickel.)

How much is scrap Inconel worth?

$2.00-$2.75/lb These prices are current as of today’s date and are subject to change, at any time due to outstanding market conditions.

What is Inconel 625 used for?

INCONEL® nickel-chromium alloy 625 (UNS N06625/W.Nr. 2.4856) is used for its high strength, excellent fabricability (including joining), and out- standing corrosion resistance. Service temperatures range from cryogenic to 1800°F (982°C).

What is F number in welding?

The F number grouping of filler metals refers to their similarity on their usability characteristics. … Like the P number, the F number designed to reduce the number of procedure qualification and welding performance qualification.
