ASTM A269 TP316L Stainless Steel Seamless Coil Tube

Product Overview

This seamless austenitic stainless steel tubing is manufactured to meet ASTM A269 standards for general service applications. Supplied in coiled form, it enables continuous, long-length installations without joints, making it ideal for complex piping systems.

TP316L Grade Designation

TP: Denotes "Tube Pipe" for tubular products
316L: Low-carbon variant of 316 stainless steel, alloyed with Molybdenum (Mo)

Key Advantages

Superior Corrosion Resistance: Molybdenum addition significantly enhances resistance to pitting and crevice corrosion in chloride environments, outperforming 304/304L grades
Excellent Weldability & Fabricability: Low carbon content (≤0.035%) minimizes harmful carbide precipitation during welding, preserving corrosion resistance at weld zones
High & Low-Temperature Service: Suitable for cryogenic applications to elevated-temperature service
Seamless Integrity: Uniform structure with no weld line, offering superior strength, reliability, and cleanliness for critical fluid handling

Standard Specifications & Manufacturing

Governing Standard

ASTM A269/A269M - Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service

Manufacturing Process

Produced as seamless tubing through processes like piercing and extrusion, followed by cold drawing to achieve precise dimensions and smooth surface finish.

Heat Treatment

All material is furnished in heat-treated (solution annealed) condition. This involves heating to ≥1040°C with rapid cooling to dissolve carbides, restore austenitic microstructure, and optimize corrosion resistance and ductility.

Testing & Inspection

Each tube undergoes rigorous testing including mandatory non-destructive electric testing (eddy current) or hydrostatic testing. Additional tests like flattening, flaring, hardness, and reverse flattening are performed per standard requirements.

Material Composition & Mechanical Properties

Chemical Composition (Weight %)

Element	Content (%)	Role & Benefit
Carbon (C)	0.035 max	Low carbon for reduced carbide precipitation and improved weldability
Chromium (Cr)	16.0 - 18.0	Provides basic corrosion resistance and forms passive protective layer
Nickel (Ni)	10.0 - 15.0	Stabilizes austenitic structure, enhancing toughness and ductility
Molybdenum (Mo)	2.0 - 3.0	Key element that greatly increases resistance to pitting and crevice corrosion
Manganese (Mn)	2.00 max	Aids in deoxidation and improves hot workability
Silicon (Si)	1.00 max	Deoxidizer and enhances strength at high temperatures
Phosphorus (P)	0.045 max	Impurity controlled to maintain toughness
Sulfur (S)	0.030 max	Impurity controlled to improve ductility and corrosion resistance

Mechanical Properties (Solution Annealed Condition)

Property	Metric Unit	Imperial Unit
Tensile Strength, min	485 MPa	70 ksi
Yield Strength (0.2% Offset), min	170 MPa	25 ksi
Elongation in 2 in. (50 mm), min	35 %	35 %
Hardness, max	217 HB / 95 HRB	217 HB / 95 HRB

Primary Application Scenarios

This tubing is designed for general service applications where reliability and corrosion resistance are critical:

Chemical & Petrochemical Processing: Transfer lines for corrosive chemicals, solvents, and process fluids
Food, Beverage & Pharmaceutical Industries: Sanitary process lines, ingredient transfer, and high-purity water systems
Heat Exchangers & Condensers: Heat transfer tubing in shell-and-tube exchangers
Instrumentation & Control Systems: Pneumatic and hydraulic control lines, pressure gauge connections
Marine & Offshore Applications: Components exposed to saltwater environments
