Hastelloy B2 Spiral Wound Gasket

hastelloy b2 spiral wound gasket

What is Hastelloy B2 Spiral Wound Gasket?

Hastelloy B2 is a nickel-molybdenum alloy with solid solution strengthening that exhibits high resistance to reducing environments such as HCl gas. The alloy prevents grain boundary carbides from forming in the welding high-hazard zone. The V-shaped Hastelloy B2 strip tape and soft filler are used to create the Hastelloy B2 spiral wound gasket. Hastelloy B2 spiral wound gasket is suitable for handling reducing acids at high concentrations and temperatures. It is also suitable for most chemical process conditions. Due to a severe loss of ductility, HASTELLOY B2 shouldn’t be exposed to temperatures in the 1000–1600°F range.

Why We Use Hastelloy B2 Outer Ring?

Hastelloy B2 spiral wound gasket is used because of its many beneficial qualities and advantages. It has excellent resistance to pitting and stress corrosion cracking and can withstand hydrochloric acid at all temperatures and concentrations. Additionally, it functions well with acetic, phosphoric, sulfuric, and wet HCl gas. The Hastelloy B2 outer ring is used to make high-temperature gas path components for the chemical industry’s pipes and valves. Also make for turbine combustors, flame holders, liners, and pressure vessels for some nuclear reactors, chemical reactors, and pressure vessels.

Characteristics of Hastelloy B2 Inner Ring

When working with reducing acids at high temperatures and concentrations, this nickel-molybdenum alloy excels. It can be used in its welded state since grain-boundary carbide precipitation is not likely to occur after welding. When oxidizing media are present, the alloy shouldn’t be used. Pharmaceuticals, acetic acid, the alkylation of ethylene, and herbicides have all been made using alloy B-2. Hastelloy B2 Inner ring has a high level of resistance to stress corrosion cracking and pitting. Also, it has significant resistance to reducing conditions like sulfuric, acetic, and phosphoric acids at all temperatures and concentrations.

Is UNS N665 Spiral Wound Style CG Gasket Suitable For Oil & Gas Applications Use?

The UNS N10665 Spiral wound-style CG gasket is considered suitable for use in the oil and gas industry. It can handle various severe chemicals and corrosion, as well as high temperature and pressure conditions. All of this makes them suitable for these applications. However, it is not advised to use Alloy B-2 in oxidizing media or in the presence of ferric or cupric salts. It’s due to its poor corrosion resistance to oxidizing environments and they may cause rapid premature corrosion failure.

What Are The Advantages And Disadvantages Of Hastelloy B2 Spiral Wound Style R Gasket?


  • This alloy offers exceptional resistance to phosphoric and acetic acid-induced reducing conditions, hydrochloric acid, and sulfuric acid.
  • They are adequately resistant to stress corrosion-induced cracking as well as corrosion of all types (including crevice and marine corrosion). These rough conditions are available in B2 Hastelloy spiral wound gaskets without an inner and outer ring.


  • The Hastelloy B2 spiral wound style R gasket cannot withstand the oxidizing conditions that are present in many industrial settings.
  • Additionally, it should not be used when there are salts such as cupric and ferric salts present. When iron and copper come into contact with HCL, these salts are created.

How Are Werkstoff Nr. 2.4617 Spiral Wound Style CGI Gasket Coated?

If you want to create industrial coatings of the stainless type you should choose aluminum and nickel powder. Because of their superior corrosion resistance and good wear characteristics, nickel-iron-aluminum coatings excel in applications requiring tough bearings. Just as in the case of Werkstoff Nr. 2.4617 spiral wound style CGI gasket. These materials are highly advised for applications that call for resistance to particle erosion, cavitation, fretting, and abrasive wear. Such harsh conditions are available in the case of Alloy B2 spiral wound gasket inner and outer rings. It’s because it is also possible to create high-strength and low-shrink coatings with them. Don’t forget that nickel-iron-aluminum coatings are ideal for building up and salvaging machinable corrosion-resistant steels.
