Product Description
1）Classification: This is an American Welding Society (AWS) standard for a bare stainless steel filler metal, specifically a low-carbon variant of the ER316 series.
2）Composition: The "ER316L" classification indicates a nominal composition of 18-20% chromium, 11-14% nickel, and 2-3% molybdenum. The "L" signifies a very low carbon content, held to a maximum of 0.03%.
3）Application: It is the preferred filler metal for welding low-carbon molybdenum-bearing stainless steels, primarily Type 316L, but is also suitable for welding standard Type 316.
4）Properties: The low carbon content is its most critical feature, as it provides exceptional resistance to intergranular corrosion or weld decay, making it ideal for applications where the welded part is exposed to corrosive conditions and high temperatures.
5）Corrosion Resistance: The addition of molybdenum gives the weld metal superior resistance to pitting and crevice corrosion, especially in environments containing chlorides, acids, and other aggressive chemicals.
6）Welding Processes: It is a highly versatile consumable suitable for various welding methods, including Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), and submerged arc welding.

AWS A5.9 ER316L is a bare stainless steel filler metal specifically designed for superior corrosion resistance.
It's a low-carbon version of ER316, featuring a controlled carbon content and the crucial addition of molybdenum.
The "L" stands for **Low Carbon**, indicating that the wire has a maximum carbon content of 0.03%.
This low carbon level is the key feature for preventing intergranular corrosion, also known as weld decay, in the weld and heat-affected zone.
Molybdenum is a critical alloying element in ER316L.
It provides excellent resistance to **pitting and crevice corrosion**, making the weld joint exceptionally durable in chloride-rich or acidic environments.
It is the standard choice for welding **Type 316L stainless steel**, but it's also highly effective for welding standard 316.
Its low carbon content makes it a safer, more versatile option for many applications.
Intergranular corrosion, or weld decay, occurs when carbon and chromium combine at grain boundaries during welding heat, depleting the surrounding area of its corrosion protection.
The low carbon content in ER316L minimizes this reaction, ensuring the weld maintains its full corrosion resistance.
ER316L is a highly versatile filler metal that works well with a range of welding methods.
It is commonly used for **Gas Metal Arc Welding (GMAW/MIG)** and **Gas Tungsten Arc Welding (GTAW/TIG)**.
The main benefits are its exceptional resistance to **pitting, crevice, and intergranular corrosion**.
It produces a strong, ductile weld that's ideal for applications in harsh, corrosive settings.
The primary difference is the carbon content.
ER316L's lower carbon level makes it more resistant to weld decay, making it a better choice for high-temperature service or when the weld will be in a corrosive environment.
ER316L is a staple in the **marine and shipbuilding industries** due to its resistance to saltwater.
It is also essential for **chemical and pharmaceutical processing**, as well as for fabricating food processing equipment.
For Gas Metal Arc Welding (MIG), a gas mixture of **98% argon and 2% carbon dioxide** is often recommended.
This blend provides a stable arc and a high-quality, clean weld bead.
Preheating is generally not required for welding with ER316L.
However, for extremely thick sections or complex joint designs, it is always best to follow a controlled welding procedure to minimize stress.
An ER316L weld deposit typically has a tensile strength of around **75,000 to 80,000 psi (517-550 MPa)**.
This provides a strong, reliable joint that can withstand significant structural and thermal stress.
To ensure optimal performance and to prevent defects, the wire must be stored in a **clean, dry, and sealed environment**.
Moisture and contaminants can lead to weld porosity and poor arc stability.
Yes, the low carbon content makes it an excellent choice for applications that operate at elevated temperatures.
It maintains its corrosion resistance better than standard ER316 in these conditions, preventing sensitization.
ER316LSi is a low-carbon, **high-silicon** version of ER316L.
The higher silicon improves weld puddle fluidity and arc stability, making it the preferred choice for MIG welding where a smooth, cosmetic bead is desired.
While its primary use is for welding 316L to itself, it can be used for some dissimilar welding, particularly when joining stainless steel to low-alloy steel.
However, other filler metals like ER309L are often better suited for this task.
The weld metal from ER316L is designed to contain a small, controlled amount of **delta ferrite**.
This ferrite helps to prevent solidification cracking, which can be an issue in fully austenitic welds.
The combination of its corrosion resistance, mechanical strength, and weldability makes it a reliable choice for pressure vessels.
It ensures the integrity of the welded joints under high-pressure and corrosive service conditions.
ER316L is ideal for this industry due to its excellent resistance to corrosion from various chemicals and cleaning agents.
It ensures a sanitary and durable weld for tanks, piping, and other process equipment.
Yes, the austenitic structure of ER316L provides it with excellent toughness and ductility at very low temperatures.
This makes it a suitable filler metal for applications in the cryogenic field.
