Manufactured specifically for low-temperature use, ASTM A321 is a specification for welded pipes crafted from stainless steel. These pipes, ranging from seamless to welded designs, are created to meet the specific requirements of high-temperature and general corrosive services. While these pipes are robust enough to withstand intense conditions, they are not suitable for ultra-low temperatures.
ASTM A321 is an austenitic stainless steel that is fortified with titanium to thwart intergranular corrosion during intense heat. The scope of the A321 specification covers both seamless and welded pipeline composition, though it is not suitable for cryogenic temperatures.
The A321 specification provides guidance for the use of pipes with a wall thickness between 3/8” and 4” made of austenitic stainless steel. These pipes are best suited for use in high temperature and generally corrosive environments and should not be employed at cryogenic temperatures.
ASTM A321 is a stabilised austenitic stainless steel alloyed with titanium to ward off intergranular corrosion at high temperatures. This versatile material is available in both welded and seamless pipe forms and is not suitable for applications requiring extraordinarily low temperatures.
The peak temperature tolerable for the A321 specification tops out at 1200F, a level unsuitable for operations involving cryogenic temperatures.
The A321 is not equipped to endure extreme cold temperatures, so using it in such conditions is not recommended.
