ASTM A269 TP316L Stainless Steel Seamless Coil Tube

Corrosion-resistant seamless austenitic stainless steel tubing for high-temperature service applications, manufactured to ASTM A269 standards and supplied in coiled form for continuous long-length installations.

Product Overview

This seamless austenitic stainless steel tubing meets ASTM A269 standards for general service applications. The coiled form enables continuous runs without joints, while the TP316L grade designation indicates:

TP: Denotes "Tube Pipe" for tubular products
316L: Low-carbon variant alloyed with Molybdenum for enhanced corrosion resistance

Key Advantages

Superior Corrosion Resistance: Molybdenum content provides enhanced resistance to pitting and crevice corrosion in chloride environments
Excellent Weldability & Fabricability: Low carbon content minimizes carbide precipitation during welding
High & Low Temperature Service: Suitable for cryogenic to elevated temperature applications
Seamless Integrity: Uniform structure without weld lines for superior strength and reliability

Standard Specifications & Manufacturing

Governing Standard: ASTM A269/A269M for Seamless and Welded Austenitic Stainless Steel Tubing

Manufacturing Process: Seamless production through piercing and extrusion with cold drawing for precise dimensions

Heat Treatment: Solution annealed condition (≥1040°C) with rapid cooling to optimize corrosion resistance

Testing & Inspection: Non-destructive electric testing, hydrostatic testing, and additional mechanical tests per standard requirements

Material Composition

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 protective layer
Nickel (Ni)	10.0 - 15.0	Stabilizes austenitic structure, enhancing toughness and ductility
Molybdenum (Mo)	2.0 - 3.0	Increases resistance to pitting and crevice corrosion
Manganese (Mn)	2.00 max	Aids deoxidation and improves hot workability
Silicon (Si)	1.00 max	Deoxidizer and enhances high-temperature strength
Phosphorus (P)	0.045 max	Controlled impurity to maintain toughness
Sulfur (S)	0.030 max	Controlled impurity to improve ductility and corrosion resistance

Mechanical Properties

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
