Trusted and recognized name in the stainless steel industry
Manufacturer and supplier of ASTM A269 Austenitic Stainless Steel 316/316L Dual Grade Tubing, ASME SA269 TP316/316L Dual Seamless Tubing
Austenitic Stainless Steel TP316/316L Dual Seamless Tubing
Known for its excellent strength and superior corrosion resistance, ASTM A269 316/316L Dual Seamless Tubing is widely considered a reliable material for demanding applications. This dual grade combines the properties of 316 and low carbon 316L, along with the addition of molybdenum, which enhances resistance to pitting and crevice corrosion. It is particularly suitable for harsh and high-stress environments where resistance to carbide precipitation and improved weldability are essential.
These dual grade seamless tubes are manufactured in accordance with international standards such as ASTM A269 and ASME SA269, along with other relevant specifications including ASTM A249, ASTM A358, and ASTM A790. Seamless tubing sizes typically range from 1/2” NB to 24” NB, while welded options like ERW and EFW are available from 6” NB to 100” NB. Wall thickness is available as per standard schedules up to XXS, depending on application requirements. All products undergo rigorous inspection and testing, including NACE MR0175, cryogenic service testing, hydrogen service, and oxygen service testing, ensuring reliability and performance in critical conditions.
ASTM A269 316/316L Dual Seamless Tubing is widely used in structural, industrial, and processing applications that demand high strength and corrosion resistance. These tubes are manufactured from high-quality raw materials, enabling them to perform effectively in extreme environments. For safe transportation and storage, the tubes are securely packed in bundles, wooden boxes, or crates to prevent damage and corrosion during transit.
