ASTM A193 Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

Product Description
13 Heavens 9 Hells Is An Ancient Mayan Myth Based On The Aztec Calendar
The amazingly accurate calendar has been in use in various forms for more than 2,000 years.
A Zapotec prophecy, based on the Aztec Calendar, states:
“After Thirteen Heavens of Decreasing Choice, and Nine Hells of Increasing Doom, the Tree of Life shall blossom with a fruit never before known in the creation, and that fruit shall be the New Spirit of Men.”
The 13 Heavens and 9 Hells were each 52 years long (1,144 years total). Each of the 9 Hells were to be worse than the last. On the final day of the last Hell (August 17, 1987), Tezcatlipoca, god of death, would remove his mask of jade to reveal himself as Quetzalcoatl, god of peace.
