| AWS A5.9 ER310 Stainless Steel Welding Wire Comment & FAQ


What is AWS A5.9 ER310 stainless steel welding wire?

AWS A5.9 ER310 is a highly-alloyed stainless steel filler metal.
It is primarily known for its exceptional resistance to heat and oxidation, making it suitable for high-temperature applications.


What is the chemical composition of ER310?

ER310 has a nominal composition of **25% chromium** and **20% nickel**.
This high alloy content is what gives the weld metal its superior properties at elevated temperatures.


What is the main application for ER310 welding wire?

Its primary use is for welding stainless steels of a similar composition, such as **Type 310 and 310S**.
It's a staple for applications that involve continuous exposure to high temperatures, such as furnaces and heat exchangers.


Why is ER310 considered a "fully austenitic" filler metal?

The high nickel content in ER310 stabilizes the austenitic microstructure, preventing the formation of ferrite.
This fully austenitic structure provides excellent toughness and good corrosion resistance, even at high service temperatures.


What types of metals can ER310 join?

Besides welding similar 310-grade stainless steels, ER310 can be used for **welding dissimilar metals**.
It's an effective choice for joining stainless steel to carbon or low-alloy steels in demanding, high-temperature environments.


Does ER310 have good oxidation resistance?

Yes, its high chromium content creates a stable oxide layer that provides outstanding resistance to **oxidation and scaling**.
This allows the weld joint to perform reliably at service temperatures up to 1100°C (2012°F).


Is ER310 suitable for cryogenic applications?

Yes, the fully austenitic microstructure of ER310 also gives it good ductility and toughness at cryogenic temperatures.
This makes it a versatile choice for applications that must withstand both extreme heat and cold.


What is the difference between ER310 and ER309?

The main difference is the alloy content.
ER310 has higher chromium and nickel percentages (25Cr-20Ni) compared to ER309 (23Cr-12Ni), giving it superior heat and oxidation resistance.


What welding processes can use ER310 wire?

ER310 is a versatile consumable compatible with various welding methods.
It is commonly used for Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), and submerged arc welding.


What are some common applications for ER310?

You'll find ER310 in furnace parts, heat exchangers, combustion chambers, and other components in the **thermal processing industry**.
It's also used in the fabrication of various high-temperature equipment.


Is there a low-carbon version of ER310?

No, unlike other grades like 308 or 309, there isn't a specific "ER310L" designation.
The standard ER310 composition already offers excellent properties for its intended high-temperature service.


What shielding gas is recommended for MIG welding with ER310?

For Gas Metal Arc Welding (MIG), a shielding gas mixture of **98% argon and 2% carbon dioxide** is often a good choice.
This helps to ensure a stable arc and a high-quality weld bead.


Is preheating necessary when welding with ER310?

Preheating is generally not required for welding with ER310 due to its excellent high-temperature properties.
However, it's always best to follow specific welding procedure specifications for your application.


How does the lack of ferrite in ER310 affect its performance?

A fully austenitic weld metal, while excellent for high-temperature resistance, can sometimes be susceptible to **solidification cracking**.
However, proper welding techniques and a controlled procedure can minimize this risk.


How should ER310 welding wire be stored?

To prevent contamination and moisture absorption, the wire must be stored in a **clean, dry, and cool environment**.
Always keep spools in their original, sealed packaging until you are ready to use them.


What is the typical tensile strength of an ER310 weld?

The weld deposit from ER310 typically has a tensile strength of around **85,000 psi (586 MPa)**.
This provides a strong and durable joint capable of withstanding thermal cycling.


Can ER310 be used for dissimilar welding to carbon steel?

Yes, its high alloy content allows it to tolerate dilution from the carbon steel base metal.
This makes it a reliable filler metal for creating strong transition joints in high-temperature service.


How do I choose between ER310 and ER316L?

Choose **ER310** for applications focused on high-temperature service and oxidation resistance.
Choose **ER316L** for superior resistance to pitting and crevice corrosion, especially in environments with chlorides.


What is the difference between ER310 and ER310Si?

ER310Si is a high-silicon version of ER310.
The higher silicon content provides better weld puddle fluidity and arc stability, which is especially beneficial for MIG welding.


Is ER310 suitable for cryogenic applications?

Yes, the fully austenitic microstructure of ER310 also gives it good ductility and toughness at cryogenic temperatures.
This makes it a versatile choice for applications that must withstand both extreme heat and cold.
