What is ASTM A193 Grade B8 Bolts?
ASTM A193 Grade B8 bolts are a type of fastener that is made from austenitic stainless steel, specifically Grade 304 stainless steel. They are commonly used in high-temperature and high-pressure applications, as well as in industries where corrosion resistance is critical, such as the chemical and petrochemical industries.
ASTM A193 is a specification that covers a range of alloy and stainless steel bolting materials for high-temperature and high-pressure service. Grade B8 is specifically designed for use in applications where high strength and excellent corrosion resistance are required.
Uses and Benefits of ASTM A193 Grade B8 Bolts
ASTM A193 Grade B8 bolts can be used in many different applications, from automotive to construction. They are strong and durable and can withstand heavy loads. Additionally, they are resistant to corrosion and oxidation, making them suitable for outdoor projects or those exposed to harsh elements. This makes them ideal for any project that requires reliable fasteners that won’t corrode or oxidize over time.
Characteristics of ASTM A193 Grade B8 Bolts
The main characteristic of ASTM A193 Grade B8 bolts is their strength and durability. They have a tensile strength rating of 125 ksi (or 862 MPa) and yield strength rating of 95 ksi (or 655 MPa). Additionally, they have an elongation rate of 12% before a fracture occurs. These bolts also feature excellent corrosion resistance due to their chromium-nickel alloy composition which makes them suitable for use in saltwater applications such as offshore drilling rigs or ships/boats. Furthermore, these bolts feature superior creep resistance which makes them ideal for high-temperature applications such as boilers or heat exchangers.
