Product Detail

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.

Key Features

🔥 High-Temperature Performance: Retains mechanical stability up to 870°C, ideal for boilers and heat exchangers.
✨ Surface Finish Options: Available in bright annealed (BA), polished, or electropolished finishes.
⚙️ Common Applications: Chemical processing equipment, marine hardware, and industrial piping systems.

Frequently Asked Questions (FAQ)

❓ What is the key difference between ASTM A269 TP316 and TP304?

ASTM A269 TP316 contains 2.0–3.0% molybdenum, which significantly improves its resistance to pitting, crevice corrosion, and chemical attacks in harsh environments compared to the non-molybdenum TP304 grade.

❓ What are the typical applications of ASTM A269 TP316 tubes?

These tubes are commonly used in demanding industries including chemical and petrochemical processing, high-temperature boilers and heat exchangers, food and pharmaceutical equipment, energy sectors, marine environments, and general industrial piping.

❓ What surface finish options are available for these tubes?

ASTM A269 TP316 tubes are available in bright annealed (BA), polished, or electropolished finishes depending on the specific application requirements.

❓ What are the mechanical properties of ASTM A213 TP316?

ASTM A213 TP316 requires a minimum tensile strength of 515 MPa, a minimum yield strength of 205 MPa (0.2% Proof), a minimum elongation of 35% in 50mm, and a maximum hardness of 90 HRB or 192 HBW.

❓ What are the equivalent international grades for ASTM A269 TP316?

Equivalent grades include Germany's X5CrNiMo17-12-2 (1.4401), Japan's SUS316, China's 06Cr17Ni12Mo2, and Russia's 08Х17Н13М2, among others.

❓ How are these stainless steel tubes packed and delivered?

They are packed in wooden boxes, plywood cases, steel strips bundled, or customized according to customer requests. Delivery conditions include cold drawn, annealed and pickled, polished, bright annealed, sand blasting, or shot blasting.
