Bolts are essential hardware components that join two or more objects together. However, not all bolts are created equal, particularly regarding their strength and durability. This is where the ASTM A194 2H and Grade 8 bolts come into play. In this blog post, we will discuss the difference between these two types of bolts and their respective applications.
Difference Between ASTM A194 2H and Grade 8
ASTM A194 2H is a high-strength, high-temperature resistant alloy commonly used in industrial and petrochemical applications. Grade 8 is a general-purpose, low-carbon steel commonly used in construction and other applications. Both materials are strong and durable, but they have some key differences.
Composition
ASTM A194 2H is an alloy that contains chromium, molybdenum, and manganese. Grade 8 is carbon steel that contains iron and carbon. Adding these elements gives ASTM A194 2H superior strength and corrosion resistance compared to Grade 8.
Temperature Range
ASTM A194 2H can be used at temperatures up to 1200 degrees Fahrenheit, making it ideal for high-temperature applications. Grade 8 has a lower temperature range of -20 to 150 degrees Fahrenheit, making it less suitable for high-temperature applications.
Yield Strength
ASTM A194 2H has a yield strength of 100 ksi, while Grade 8 has a yield strength of 36 ksi. This means that ASTM A194 2H is much stronger than Grade 8 and can withstand more force before it begins to deform.
Applications
ASTM A194 2H is typically used in industrial applications such as valves and fittings, while Grade 8 is more commonly used in construction applications such as bolts and screws.
Conclusion
ASTM A194 2H and Grade 8 bolts are designed to handle high-stress applications. However, they differ in their manufacturing process, threading, and applications. While ASTM A194 2H bolts are ideal for high-pressure and high-temperature applications, Grade 8 bolts are more commonly used in machinery and automotive applications. Choosing the right bolt for each application is essential to ensure optimal performance and safety. It is always advisable to consult with a professional to ensure you use the right bolt for your specific needs.
