Hastelloy Flanges are corrosion-resistant, high-performance components used in a variety of industrial applications. Their impressive chemical composition is comprised primarily of iron, nickel and chromium, with potentially small amounts of molybdenum, tungsten, carbon and manganese. The optimal combination allows Hastelloy Flanges to perform in extreme environments — ranging from acidic or alkaline solutions to oxidizing conditions or exposure to temperatures spanning from cryogenic to elevated levels. As such, they can be used as thermal processing equipment in various industries requiring impact tolerance, superior reliability and superior resistance to oxidation and corrosion.

Hastelloy Flanges are a family of nickel-chromium-molybdenum alloys with excellent corrosion resistance in many industrial environments. This alloy is known for its high-temperature strength, good fabricability and strong resistance against pitting, crevice corrosion and stress-corrosion cracking. It can also withstand diverse types of chemical environments and offer outstanding weldability. Hastelloy Flanges have been used in the production of nuclear fuel reprocessing plants, chemical industries, oil refineries, power generation plants and in applications involving concentrated saline water due to their stress rupture strength and fatigue strength at elevated temperatures. They are available in various sizes, shapes and forms, such as plate flanges, steel flanges, slip-on flanges etc., making them an ideal choice for multiple uses such as pipe connection devices and instrumentation accessories/fittings.

Hastelloy Flanges are available in several grades, each with different alloy compositions and properties suited for specific applications.

Some of the commonly used grades of Hastelloy Flanges are:

Hastelloy B2 Flanges 

This grade is highly resistant to hydrochloric acid and other highly reducing chemicals. It also offers excellent resistance to stress corrosion cracking.

Hastelloy B3 Flanges 

Hastelloy B3 Flanges are flanges made from a nickel-molybdenum alloy called Hastelloy B3. This material is highly resistant to corrosion in various reducing environments.

Hastelloy C22 Flanges 

This grade is highly resistant to pitting, crevice, and stress corrosion cracking. It is ideal for use in the chemical processing and pharmaceutical industries.

Hastelloy C276 Flanges 

This grade has a high resistance to corrosion in a wide range of severe environments. It is suitable for chemical processing, pulp and paper production, and waste treatment plants.

Hastelloy X Flanges

This grade is strong, durable and offers excellent high-temperature strength. It is commonly used in gas turbine engines, boilers and pipe systems in the chemical processing industry.

FAQ'S

What Is the Best Welding Type for Hastelloy Flanges?

The best welding type for Hastelloy flanges is gas tungsten arc welding (GTAW) or shielded metal arc welding (SMAW). These types of welds are highly resistant to corrosion and cracking, making them ideal for joining Hastelloy flange components.

Are Hastelloy Flanges Strong?

Yes, Hastelloy flanges are very strong and can be used in high-pressure applications due to their excellent strength properties.

Is Hastelloy Flanges Heat Resistant?

Yes, Hastelloy flanges are highly heat resistant, making them suitable for use in high-temperature environments.
