China Suppliers Factory for ASTM A269/A270/A213 TP316 Stainless Steel Seamless Tubes - Fast Delivery Available
Introduction
ASTM A269 TP316 is a molybdenum-bearing austenitic stainless steel tube, designed for demanding corrosive and high-temperature applications. As part of the 316 family, it incorporates 2.0–3.0% molybdenum (Mo), significantly enhancing its resistance to pitting, crevice corrosion, and chemical attack compared to non-molybdenum grades like TP304. The standard carbon content (≤0.08%) makes it suitable for applications where post-weld heat treatment is feasible or sensitization risks are managed.

Frequently Asked Questions (FAQ)
What is ASTM A269 TP316?
ASTM A269 TP316 is a molybdenum-bearing austenitic stainless steel grade designed for tubes used in high-temperature and highly corrosive applications. The addition of 2.0-3.0% molybdenum provides improved resistance to pitting and crevice corrosion compared to standard TP304 stainless steel.
What are the mechanical properties of ASTM A213 TP316?
ASTM A213 TP316 exhibits a minimum tensile strength of 515 MPa, a minimum yield strength of 205 MPa, and a minimum elongation of 35%. The maximum hardness allowed is 90 HRB (Rockwell) or 192 HBW (Brinell).
What are the standard dimensions and size deviations for ASTM A269 tubes?
Standard outside diameters range from 1/8" NB to 32" NB. According to ASTM A269, permissible variations in outside diameter range from ±0.005 in. for smaller tubes (up to 1 1/2 in.) up to ±0.050 in. for larger tubes (12 to 14 in.), with wall thickness variations kept within ±10% to ±15%.
What surface finishes are available for TP316 tubes?
These tubes can be supplied in bright annealed (BA), polished, or electropolished finishes. Standard delivery conditions include cold drawn, annealed and pickled, sand blasting, or shot blasting.
What are the equivalent international grades for ASTM A269 TP316?
Equivalent international grades include Germany's WNr 1.4401 (X5CrNiMo17-12-2), Japan's SUS316, China's GB 06Cr17Ni12Mo2, and Russia's GOST 08Х17Н13М2.
What inspections and tests are performed on these tubes?
Tubes undergo 100% PMI (Positive Material Identification) testing. They are delivered with an EN10204.3.1B Mill Test Certificate, and third-party inspections are widely accepted to guarantee material quality.
