AWS A5.9 ER316 is a bare stainless steel filler metal specifically designed for its enhanced corrosion resistance.
It is most notably characterized by the addition of **molybdenum**, which provides superior performance in aggressive environments.
The key difference is the presence of **2-3% molybdenum** in ER316, which is absent in ER308.
This molybdenum content gives ER316 much better resistance to **pitting and crevice corrosion**, especially in chloride-rich or acidic conditions.
ER316 has a nominal composition of **18-20% chromium** and **11-14% nickel**.
The presence of **2-3% molybdenum** is the crucial element that sets it apart from standard 300 series stainless steels.
It is the standard choice for welding **Type 316 and 316L stainless steels**.
It can also be used to weld other molybdenum-bearing stainless steels and for certain dissimilar metal applications where high corrosion resistance is needed.
Pitting corrosion is a localized form of corrosion that creates small holes or "pits" in the metal, particularly in chloride environments.
The molybdenum in ER316 significantly increases the alloy's resistance to this type of attack, protecting the weld joint from premature failure.
ER316 is a highly versatile filler metal compatible with multiple welding methods.
It is commonly used for **Gas Metal Arc Welding (GMAW/MIG)**, **Gas Tungsten Arc Welding (GTAW/TIG)**, and submerged arc welding.
The primary benefits include excellent resistance to **pitting and crevice corrosion**, good mechanical strength, and suitability for both high-temperature and cryogenic applications.
It produces a strong, ductile weld that can withstand demanding service conditions.
The "L" in ER316L signifies a **low carbon content** (max 0.03%).
This makes ER316L even more resistant to **intergranular corrosion** or weld decay, making it the preferred choice for applications that will be exposed to elevated temperatures for extended periods.
Choose **ER316L** when the welded component will be exposed to temperatures that could cause sensitization, leading to weld decay.
It's also the safer choice for applications where long-term corrosion resistance is absolutely critical.
For Gas Metal Arc Welding (MIG), a mixture of **98% argon and 2% carbon dioxide** is often recommended.
This combination provides a stable arc and a high-quality weld bead with minimal spatter.
Preheating is generally not necessary when welding with ER316 stainless steel.
However, for extremely thick sections or complex joint designs, following a controlled welding procedure is always advisable.
ER316 is a staple in the **marine and shipbuilding industries** due to its resistance to saltwater corrosion.
It's also heavily used in **chemical processing plants**, **pharmaceutical manufacturing**, and for food processing equipment.
The weld metal from ER316 maintains its strength and corrosion resistance at elevated temperatures.
It is suitable for service up to approximately 800°C (1472°F) in non-corrosive atmospheres, where its creep strength is beneficial.
An ER316 weld deposit typically has a tensile strength of around **80,000 psi (550 MPa)**.
This provides a strong, reliable joint that can handle significant structural and thermal stresses.
To ensure the highest quality welds, the wire must be stored in a **clean, dry, and sealed environment**.
Moisture and contaminants can lead to weld defects like porosity and affect the wire's performance.
It is sometimes used for joining stainless steel to other metals, but other consumables like ER309 are often more suited for that specific task.
ER316's primary strength lies in its ability to weld molybdenum-bearing stainless steels.
ER316LSi is a **low-carbon, high-silicon** version of ER316.
The added silicon improves weld puddle fluidity, arc stability, and produces a smoother weld bead, making it an excellent choice for MIG welding applications.
Yes, the austenitic structure of ER316 provides good toughness and ductility at very low temperatures.
This makes it a suitable filler metal for applications in the cryogenic industry.
The weld metal from ER316 is designed to contain a small, controlled amount of **delta ferrite**.
This helps to prevent solidification cracking, which can be an issue in fully austenitic welds.
The excellent corrosion resistance of ER316, especially against chlorides, makes it perfect for fabricating food processing equipment.
It resists corrosion from cleaning agents and food products, ensuring a sanitary and long-lasting surface.
