An acoustic beam simulation makes use of ultrasonic beams that are used in a phased array (PA) ultrasonic, which is considered to be an advanced method of ultrasonic testing.This method is better at finding flaws in manufactured materials such as welds. The acoustic beam simulation mimics how the ultrasonic beam in a PA probe can be focused and...

Alloy 2507

Definition - What does Alloy 2507 mean?

Alloy 2507 is a super duplex stainless steel alloy with a mix of 25% chromium, 7% nickel and 4% molybdenum. The chemical composition of this alloy is as follows:

Cr – 25%

Ni – 7%

Mo - 4%

C – 0.030% max

N – 0.24% to 0.32%

Mn – 1.2% max

Si – 0.8% max

Cu – 0.5% max

P – 0.035% max

S – 0.020% max

Fe – Balance or remaining percentage

Alloy 2507 is also known as Super Duplex 2507.

Corrosionpedia explains Alloy 2507

Industrial nomenclature or the recommended grade for Alloy 2507 is UNS S32750.

Alloy 2507 contains high quantities of chromium, nickel, molybdenum and nitrogen which makes it an excellent inhibitor to chloride pitting and crevice corrosion attack. This alloy has a duplex structure that provides exceptional resistance to chloride stress corrosion cracking. This alloy possesses excellent mechanical properties in terms of light weight and durability, thus translating to lower fabrication costs for mechanical materials. It is resistant to corrosion by organic acids such as formic acid and acetic acid. It also shows corrosion resistance to all inorganic acids that contain chlorides.

Its use is limited to applications below 315 °C (599 °F); at higher temperatures it loses both corrosion resistance and its toughness properties.
