B564 UNS06625 ELBOW

Inconel 625 Steel Elbow

AnInconel 625 steel elbow is a piping fitting made from Inconel 625, a high-performance nickel-chromium alloy known for its excellent resistance to extreme environments, including corrosion, oxidation, and heat. This type of elbow is used to change the direction of flow in piping systems while maintaining the unique properties of Inconel 625.

Key Features

1. Material Composition:

   • Inconel 625 is primarily composed of:
     • Nickel (58% min)
     • Chromium (20-23%)
     • Molybdenum (8-10%)
     • Small amounts of other elements such as iron, niobium, and titanium.
   • This composition provides exceptional strength, toughness, and resistance to pitting and stress corrosion cracking.

2. Design:

   • Typically available in standard angles such as 45 degrees and 90 degrees.
   • Can be produced in both long radius (LR) and short radius (SR) designs, depending on application requirements.

3. Standards:

   • Inconel 625 steel elbows are manufactured according to various industrial standards, including:
     • ASME B16.9: Specification for factory-made wrought steel butt-welding fittings.
     • ASTM B446: Specification for Inconel 625 rod and bar.
     • API 598: Standard for valve inspection and testing.

4. Sizes of Inconel 625 Steel Elbow:

   • Available in a wide range of sizes to fit different pipe diameters, typically from 1 inch (25 mm) to 48 inches (1200 mm) or larger.
