Inconel 601 Fittings and Flanges

Inconel 601 is a nickel-chromium alloy that is highly resistant to oxidation through 2200°F. 601 alloys develop a tightly adherent oxide scale which resists spalling even under severe thermal cycles.

Chemical composition

Inconel alloy 601 introduces superior creep rupture strength and is extensively utilized in the apparatus that operate under high temperatures for an extended or longer course of time. The substantial nickel and chromium contents of INCONEL alloy 601 in conjunction with its content of aluminum give the alloy superior resistance to high temperature corrosion mechanisms.

Physical Properties

Specification of Flange

The specified ASTM Standard Specification for Nickel Alloys Flanges is ASTM B 564 with manufacturing standard such as ANSI/ASME B16.5, B16.47, BS4504, B 16.47 Series A & B, BS 10, EN-1092, DIN, etc.

According to application and uses in pipes and tubes Inconel 601 Flanges are broadly grouped into different sort, for example, Welding Neck Flange(WNF) & Long Welding Neck Flange(LWNF), Slip-on Flange(SOF), Lap Joint Flange(LJW), Blind Flange, Socket Welding Flange (SWF), Threaded Flange(THW), Plate Flange.

Inconel 601 Flange for the most part has different face type, for example, Flat Face (FF), Raised Face (RF), Ring Type Joint (RTJ), blind flange, with various class rating as 50 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16,din 2.4856 , 25, 40 & ANSI B16.5.

Specification of Fittings

The specified ASTM Standard Specification for Nickel Alloys Pipe Fitting is ASTM B 366, having Specific manufacturing Standards as ASME/ANSI B16.9, ASME B16.28, MSS-SP-43.

Inconel 601 pipe fittings are categorically available are Elbow, Reducer, Tee, Coupling, Bend, Stub End, Cap, Nipple, Washer, Cross, Union etc. which are available in different types such as Welded, Seamless and Fabricated having thickness range from 5s, 10s, 40s, 80s, 10, 20, 40, STD, 60, 80, XS, 100, 120, 140, 160, XXS available with NACE MR 01-75.

Mechanical Properties

Application

Alloy 601 Flange and Fittings have good creep rupture strength, and the alloy is widely used for equipment that must withstand extended exposure to high temperatures. The alloy's usefulness for such applications is increased by its resistance to oxidation and other forms of high-temperature corrosion
