ASTM A193 is a specification for high-strength stainless steel bolts used in extreme environments such as chemical plants, offshore oil rigs, and power generation facilities. The grade B8T hex bolt is a specific type of ASTM A193 bolt that is made from Type 321 stainless steel and is heat-treated for added strength.


Features One of the main features of ASTM A193 Grade B8T hex bolts is their high tensile strength, which makes them ideal for use in harsh environments. The addition of titanium in Type 321 stainless steel improves the bolt's resistance to corrosion and oxidation, increasing its durability and longevity. These bolts also have excellent resistance to high temperatures, making them suitable for use in applications where the temperature may exceed 800°F.

Machining Machining ASTM A193 Grade B8T hex bolts can be challenging due to their high strength and resistance to heat. These bolts require specialized equipment and techniques for cutting and shaping. Carbide tools are recommended for machining as they can withstand the high temperatures generated during the process. Additionally, proper lubrication is crucial to prevent galling and seizing of the bolts.
