Seamless Pipe Low Temperature ASTM A333 ASME SA333

ASTM A333 (ASME S/A-333) Pipe grades permit low temperature service. ASTM
A333 Pipe shall be made by the seamless or welding process with the addition of no
filler metal in the welding operation. 
This ASTM specification is written so that the end user and the manufacturer can agree upon, and clearly understand, the properties and capabilities of the piping product being supplied. In contrast with national codes (like API, ASME or CSA), ASTM A333 is rarely stipulated by national or state-level legal requirements.
There are several grades in A333, each with different steelmaking approach to improve the steel’s impact properties at lower temperatures. Several grades have nickel (Ni) additions, and are capable of high toughness at cryogenic temperatures as low as -320F (-195C). Many of these grades would be considered rare, and in the experience of Bri-Steel, they are expensive to procure and may be difficult to find a capable fabricator with an proven weld procedure. The exception to this is Gr6, which is quite common and is regularly stocked in colder regions of North America. A333 Gr6 has proven impact toughness at -50F (-45C), and is commonly used in applications where the piping is exposed directly to cold environments during construction and/or in operation. 
A333 Gr6 is also commonly used for pressure piping of compressed gas, where a crack would be expected to have catastrophic consequences. 
Material & Manufacture
ASTM A333 pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.
Heat Treatment Requirements
All seamless and welded pipe shall be treated to control their microstructure by the following methods:
Normalizing per A 333/A 333M-05 section; section or section Quenched and
Tempered per A 333/A 333M - 05 section Double Normalized and Tempered per A 333/A 333M -05 section
