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.

This custom Bach Stradivarius ML 37 SN# 151180 was custom modified by legendary studio trumpeter Charly Davis. There is not a dent, scratch, ding, or trauma, on this horn. Originally manufactured around 1977 You got to play this horn to believe!!!! Charly acquired the valve section from another manufacturer who was using the valve section to try out different Lead-pipe and Bell combinations.this valve section was never hardly played. The ports in the valves are still brass colored , not tarnished from use. Charly had a silver 25 lead-pipe drawn and mounted it to the trumpet.. He also acquired an older finger hook for that vintage sculpted look. The 3rd valve slide now has a stop screw instead of that awkward bar and nuts that Bach uses on the Bb’s. He also copied the all metal top caps from a friends 1928 NY Bach Strad. Because of the two different top cap and finger button combinations the horn has received 2 Reeves valve alignments. There are also many extras for the performer to fine tune this incredible instrument. Here’s a list: 1.Gold Plated Bach Stradivarius model 37 ML 2. 3 Tuning slides all gold plated: a. Bach rounded tuning slide b. Bach tuning slide with Amado water key c. Standard Bach tuning slide 3. Bach weighted bottom caps and standard Bach bottom caps 3 sets of bottom caps: a. Mark Curry weighted bottom caps b. Bach heavy bottom caps c, standard Bach bottom caps 4 Sterling silver lead-pipe #25 (with old style finger hook), I got silver tubing from Dick Akright, and got Zig Kanstul to draw a 25 lead-pipe from silver 5. Two Reeves valve alignments, one for each set of top caps: a. standard Bach top caps, stem and finger buttons(Reeves valve alignment) b.Extra top caps duplicated from 1928 Bach with gold plated stems and flat finger tips (with reeves valve alignment) 7. Annealed 37 bell 8. Custom 3rd valve slide stop 9.
