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 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.

On Episode 11 of the web series Hands-On Cars, Kevin Tetz shows you how to bodywork the Camaro and use Primer-Surfacer, Guide Coat and different styles of sanding blocks to get it laser straight. Then KT takes you for a ride in a beautiful unrestored 1959 Chevy Impala!

Kevin’s buddies show up to help bodywork the Camaro – including Chris Slee from Kiwi Classics and Customs and TC Penick from Bay One Customs, plus engine builder John Bouchard. In a day’s time, the bodywork was done on the Camaro, the gaps were set, a new trunk lid was added, a new hood was shaped into place with a piece of 2×4 and an Eastwood MIG 175 welder – and then KT laid down the Eastwood High Build Primer-Surfacer and started block sanding to get the panels laser straight.
This is definitely a crew of Eastwood Guys! Are You an Eastwood Guy?
