Alloy steel bolting materials are often used for high temperature service due to their enhanced strength and resistance to heat, corrosion, and oxidation. Some common alloy steel bolting materials for high temperature service include:

1. Grade B7: This is a medium carbon alloy steel bolt material typically used in applications ranging from -20°F (-29°C) to 1000°F (538°C) for petroleum and chemical industries.

2. Grade B16: This heat-treated chromium-molybdenum-vanadium alloy steel is suitable for high-temperature service up to 1100°F (593°C) and is commonly used for pressure vessels and valves.

3. Grade B8: Made from type 304 stainless steel, this alloy is used in high-temperature environments ranging from -325°F (-198°C) to 1000°F (538°C) in various industries, including chemical and petroleum.

4. Grade B8M: Similar to Grade B8, this alloy steel bolting material is made from type 316 stainless steel and is specifically designed for corrosive high-temperature applications.

5. Grade B8T: This alloy steel is made from type 321 stainless steel, which is stabilized with titanium, making it suitable for high-temperature environments up to 1500°F (816°C), particularly in the petrochemical industry.

6. Grade B8C: This alloy is made from type 347 stainless steel, which is also stabilized, making it resistant to sensitization and suitable for high-temperature service up to 1500°F (816°C).

These are just a few examples of the alloy steel bolting materials commonly used for high temperature service. It is important to choose the appropriate grade based on the specific temperature, pressure, and corrosion requirements of the application.
