Applications and Advantages of Alloy 800 Fasteners in Various Industries

Would you like to learn more about the advantages of using alloy 800 fasteners? Alloy 800, a high-grade stainless steel alloy, is frequently employed for industrial fastening applications. It has superior corrosion resistance, strength, and toughness compared to regular stainless steel, making it an ideal choice for various industries. This blog post will explore the applications and advantages of using alloy 800 fasteners in various industries. Learn how this versatile material can meet your project needs with its remarkable properties!

Aerospace Industry

Alloy 800 fasteners are especially useful in aerospace due to their excellent high-temperature strength and corrosion resistance. In addition, these fasteners have superior mechanical properties compared to other grades of stainless steel. The alloy is specifically designed to withstand elevated temperatures without experiencing embrittlement or loss of strength, unlike many other alloys. Furthermore, its high nickel content protects against chloride stress corrosion cracking, which can compromise the integrity of parts exposed to harsh environments. Because Alloy 800 fasteners retain their properties even under extreme conditions such as those seen in aerospace applications, they are often used in components like engine mounts and landing gear systems for increased durability and safety.

Petrochemical Industry

Alloy 800 fasteners, made of nickel-iron-chromium alloy, are popular in many industries, particularly petrochemicals, due to their high strength and corrosion resistance. They have excellent anti-scaling properties, making them ideal for use in sulfuric acid or steam condensate environments. The impressive scaling resistance of Alloy 800 fasteners prevents external and internal piping equipment surface attacks at high temperatures up to 843°C (1550°F). These features make it a preferred choice for oil refineries, power plants, and chemical processing units. Additionally, Alloy 800 is highly oxid-resistant, making it suitable for extreme conditions like thermal cycling.

Power Generation Industry

Experts highly recommend the use of alloy 800 fasteners in the power generation industry. These fasteners offer excellent corrosion resistance at high temperatures, making them suitable for demanding applications such as turbines and exhaust systems. They have superior tensile strength and good creep rupture properties, making them ideal for withstanding the high cyclic stresses experienced in steam piping and other dynamic operations. Other benefits include reduced weight due to their nickel-chromium composition, superior electrical insulation, and excellent formability and weldability, simplifying installation. In conclusion, Alloy 800 is an ideal choice for power generation systems due to its superior performance against high-temperature oxidation and corrosive environments.

Chemical Industry

Alloy 800’s unique combination of high strength, corrosion resistance, and oxidation resistance makes it a great choice for fasteners in the chemical industry. Its austenitic structure provides excellent heat resistivity and good mechanical properties at elevated temperatures – characteristics that are essential for withstanding harsh chemicals. Its low carbon content also ensures Alloy 800 Fasteners won’t suffer from intergranular stress corrosion cracking common to other alloys operating in highly corrosive environments. This makes them well-suited for use in sulfuric acid processing lines and numerous similar applications found within the chemical industry.

Food Industry

The food industry utilizes Incoloy 800 fasteners in equipment that requires frequent cleaning and sanitation. These fasteners provide excellent resistance to corrosion and oxidation, making them ideal for use in food processing equipment. They are also highly durable, ensuring they can withstand frequent cleaning and sterilization processes.


Many industries, including aerospace, petrochemical, power generation, chemical, and food, widely use alloy 800 fasteners due to their numerous advantages. They provide high-temperature resistance, excellent corrosion resistance, and high-stress retention capabilities. The applications of Alloy 800 fasteners in these industries ensure that machines operate efficiently, safely, and reliably.
