1. Standard: ASTM A213 / ASME SA213
2. Size: 1/8”-5”
3. Thickness: 0.381 mm - 12.7 mm
4. Equivalent:UNS S31603, WNR.1.4404, WNR.1.4435, AISI 316L
ASTM A213 316L Stainless Steel Tube is a low carbon, molybdenum-containing austenitic stainless steel. 316L is more resistant to general corrosion, pitting and crevice corrosion than traditional chromium-nickel austenitic stainless steels such as 304, especially in sour environments. A213 TP316L tube also provides higher creep strength, rupture stress and tensile strength at elevated temperatures. The recommended temperature range includes -425°F to 1,200°F (-255°C to 605°C).

SS 316L Seamless Tube Heat Treatment
Annealing temperature is generally 1040-1150°C, ASTM A213 316L stainless steel tube is annealed according to ASTM A213 specification, with uniform grain structure and maximum corrosion resistance.
316L SS Pipe Surface Condition
Austenitic steel pipes should be pickled to remove the oxide scale. Pickling is not required when bright annealing is used. If any special surface treatment requirements are required, contact us, SS TP316L Seamless Round Pipe Supplier.
