Hastelloy B2 Fasteners

Hastelloy B2 fasteners are high-performance bolts, nuts, studs, and screws manufactured from Hastelloy B2 (nickel-molybdenum alloy). They are specifically designed for extremely corrosive environments, especially those involving strong reducing acids.

🔹 What Is Hastelloy B2?

Hastelloy B2 is a nickel-molybdenum alloy developed by Haynes International (original developer of Hastelloy alloys). It provides excellent resistance to hydrochloric acid and other reducing chemicals, making it ideal for critical chemical processing applications.

UNS Number: N10665
Werkstoff No.: 2.4617

🔹 Key Features

• Outstanding resistance to hydrochloric acid (all concentrations)

• Excellent performance in reducing environments

• Resistant to pitting, crevice corrosion, and stress corrosion cracking

• Maintains strength at elevated temperatures

• Good fabricability for threaded fasteners

🔹 Available Fastener Types

• Hex bolts & heavy hex bolts

• Hex nuts

• Stud bolts & threaded rods

• Socket head cap screws

• Washers and custom-machined fasteners

🔹 Standard Specifications

• ASTM B574 / ASME SB574 – Nickel alloy bolts and fasteners

• ASME B18.2.1 / B18.2.2 – Dimensional standards

• NACE MR0175 / ISO 15156 – For sour service (oil & gas)

🔹 Typical Applications

• Chemical processing plants

• Acid handling systems

• Reactors and heat exchangers

• Petrochemical piping systems

• Offshore and marine chemical equipment

🔹 Advantages

• Long service life in highly corrosive chemical environments

• Maintains mechanical integrity under acid exposure

• Reliable for critical bolted connections

• Reduces maintenance and replacement costs

If you want, I can also create a comparison chart of Hastelloy B2 vs B3 vs C-276 fasteners, highlighting corrosion resistance, temperature limits, and ideal applications, to help choose the right grade.

🔩 Hastelloy B3 Fasteners

Hastelloy B3 fasteners are high-performance bolts, nuts, screws, and studs made from Hastelloy B3, a nickel-molybdenum alloy with exceptional resistance to strong reducing acids, particularly hydrochloric acid. They are designed for critical chemical and industrial applications where both corrosion resistance and mechanical strength are required.

🔹 What Is Hastelloy B3?

Hastelloy B-3 is a nickel-molybdenum alloy developed by Haynes International. Compared to B2, B3 offers:

• Lower iron content for enhanced resistance to hydrochloric acid

• Excellent corrosion resistance in strong reducing environments

• Good mechanical properties for fastening and structural applications

UNS Number: N10675
Werkstoff No.: 2.4605

🔹 Key Features

• Exceptional resistance to strong reducing acids

• Maintains mechanical strength at elevated temperatures

• Available in standard fastener sizes and grades

• Suitable for chemical processing, petrochemical, and acid-handling equipment

• Resistant to stress corrosion cracking

🔹 Standard Specifications

• ASTM B564 / ASME SB564 – Nickel alloy forged fasteners

• ASTM F467 – Standard fastener specifications (bolts, nuts, screws)

• NACE MR0175 / ISO 15156 – Sour service compliance (if required)

🔹 Applications

• Chemical reactors, vessels, and pipelines handling hydrochloric acid and other reducing acids

• Pressure vessels and storage tanks in corrosive environments

• Industrial and petrochemical plants requiring high-integrity fastening solutions

• Offshore chemical systems exposed to reducing agents

🔹 Advantages

• Outstanding corrosion resistance in aggressive reducing chemicals

• High strength and durability for critical industrial fasteners

• Long service life in harsh environments

• Reliable performance in acidic and high-pressure applications

I can also create a comparison chart of Hastelloy B2 vs B3 fasteners, showing chemical resistance, mechanical strength, and ideal applications, which helps in selecting the right alloy for specific chemical systems.

The different composition, production methods and other mechanical and physical properties all matter. The SS 304 hex bolt is the most used in terms of the material grade as the 304 is a basic austenitic stainless steel with chromium and nickel composition. The torque strength is also good. The next most used is the ss 316 hex bolt due to the added corrosion resistance as it has molybdenum added to the content. The length of the bolts can range from 1 inch to 24 inches depending on the standard and application type. Some applications demand Stainless Steel heavy hex bolt due to the heavy load bearing nature. The bold diameter can range from ½ inches to 2 ½ inches depending on the standards such as the hex bolts din 933. The different standards are useful to maintain a universal measurement and identification of the bolts as they are used in different applications. The thread types, lengths, widths, head and other properties of the bolts vary with different standards such as the hex bolts din 931. The bolts are also specified for different applications such as fittings and flanges. There are differences to suit the connection types such as the hex flange bolts and hex fittings bolts. The fasteners also come with different standards for different use cases. To have an international measure, there are ISO numbers to indicate the types such as the hex bolt iso 4014. Please feel free to contact us for more information and pricing of the hex bolts and other types of fasteners.
