E309L-17 Stainless Steel Stick Electrodes – 14" Long, 10 lb Metal Can (Select Size From Options Above)

Low-carbon stainless steel electrodes for stainless fabrication and stainless-to-carbon-steel welding.
E309L-17 stainless steel Stick electrodes provide approximately 24% chromium and 13% nickel filler metal with reduced carbon compared with standard 309. The low-carbon formulation helps reduce the possibility of intergranular carbide precipitation while providing good crack resistance.

E309L-17 is a versatile choice for stainless steel fabrication and is especially useful when welding stainless steel to carbon steel. The electrode provides easy arc starts and re-strikes, low-spatter performance, self-releasing slag, and a smooth bead appearance.

Important Ordering Information: Electrodes are 14" long, priced per pound, and sold in 10 lb metal cans.

Available Electrode Sizes

Select either 3/32" or 1/8" electrode diameter from the options above. Both sizes are supplied in 14" lengths.

Why Choose E309L-17?

• Stainless-to-Carbon-Steel Welding: A good choice for compatible dissimilar-metal joints involving stainless and carbon steel.
• Low-Carbon Weld Metal: Helps reduce the possibility of intergranular carbide precipitation.
• Good Crack Resistance: Designed to provide dependable performance in demanding stainless welding applications.
• Easy Arc Starts: Provides easy strike and re-strike characteristics.
• Low-Spatter Arc: Helps produce cleaner welds with less post-weld cleanup.
• Self-Releasing Slag: Helps simplify slag removal after welding.
• Smooth Bead Appearance: Produces a smooth bead ranging from slightly concave to flat.
• All-Position Capability: Can be used in multiple welding positions with proper technique and parameters.
• 14" Electrode Length: Both available Arc-Zone sizes are supplied in 14" lengths.

Stainless-to-Carbon-Steel Applications

One of the key uses for E309L-17 is joining stainless steel to carbon steel. Its higher chromium and nickel content helps provide the alloying needed for compatible dissimilar-metal welding applications.

This makes E309L-17 a useful electrode for fabrication, repair, maintenance, and modification work where stainless components must be joined to carbon steel.

Low-Carbon 309L Composition

E309L-17 provides approximately 24% chromium and 13% nickel filler metal. The "L" identifies the electrode as a low-carbon version of 309.

Reducing carbon helps lower the possibility of intergranular carbide precipitation while maintaining good crack resistance and corrosion-resistant weld characteristics.

Typical Weld Metal Properties

All-Position Welding

E309L-17 can be used for all-position welding. Because the slag freezes more slowly, additional care should be used when welding out of position.

Flat and horizontal welding provide smooth arc transfer. A slight weave may be helpful when welding vertical-up.

Frequently Asked Questions

How long are the E309L-17 electrodes?
Both the 3/32" and 1/8" electrodes are 14" long.

What is E309L-17 commonly used for?
E309L-17 is used for compatible stainless steel welding applications and can be a good choice when joining stainless steel to carbon steel.

What does the "L" mean?
The "L" indicates a low-carbon version of 309 stainless filler metal. The reduced carbon content helps decrease the possibility of intergranular carbide precipitation.

Can E309L-17 weld stainless steel to carbon steel?
Yes. Washington Alloy specifically identifies 309L electrodes as a good choice for compatible stainless-to-carbon-steel welding applications.

What sizes are available?
This listing is available in 3/32" and 1/8" diameters. Both sizes are supplied in 14" lengths.

What polarity can I use?
Washington Alloy lists typical E309L-17 SMAW procedures for DCEP or AC.

Can E309L-17 be used in all positions?
Yes. It is an all-position electrode. However, the slag freezes more slowly, so additional care should be used when welding out of position. A slight weave may be helpful for vertical-up welding.

How are these electrodes sold?
They are priced per pound and sold in 10 lb metal cans.

Can I buy only one pound?
No. The minimum purchase is one complete 10 lb metal can.

How do I choose the correct electrode diameter?
Choose the diameter based on material thickness, joint design, welding position, available amperage, and your approved welding procedure.
