The Chiyoda E309L-16 is a premium, extra-low carbon rutile-type electrode designed for high-integrity stainless steel welding. It is the industry standard for joining 300 stainless steel to mild or low-alloy steels. With its advanced moisture-resistant flux coating and superior slag lift, it delivers exceptional radiographic integrity and a clean, professional finish.
As a leading Chiyoda industrial welding supplier in Malaysia, we provide genuine Chiyoda solutions for refineries, food processing plants, and marine repair workshops nationwide.
The Chiyoda 309L-16 is engineered for high alloy content (22% Cr / 12% Ni), making it indispensable for specific engineering challenges:
Superior Dissimilar Welding: Specially formulated to join stainless steel to mild steel or low-alloy steel without risking weld brittleness or cracking.
Enhanced Slag Control: Features an "Improved Slag Lift" technology that makes post-weld cleaning fast and effortless.
Extra-Low Carbon (309L): The "L" stands for low carbon, which minimizes carbide precipitation and ensures maximum corrosion resistance in the weld zone.
All-Positional Excellence: Provides a smooth arc and low spatter in all positions (except vertical down), ensuring high-quality beads even in restricted spaces.
Radiographic Integrity: Produces welds with high radiographic quality, meeting the strict inspection standards of the oil, gas, and pressure vessel industries.
The Chiyoda 309L-16 is versatile, performing exceptionally with both AC and DC+ power sources.
Maintenance & Repair: Welding stainless steel liners or cladding to mild steel structures.
Marine Engineering: Joining stainless fittings to mild steel hulls or decks.
Food Processing: Fabrication of transition joints in stainless steel machinery.
Power & Chemical: Welding of high-alloy 309 and 309L base metals in heat exchangers and furnaces.
Preparation: Ensure the base metals are clean and free from grease, oil, and moisture to maintain the extra-low carbon integrity.
Arc Length: Maintain a short arc to ensure the best shielding gas coverage from the rutile flux.
Storage: Store in a dry area. While the flux is moisture-resistant, keeping electrodes in a quiver (hot box) during site work is recommended for critical applications.
Don't compromise on weld strength. As an authorized dealer, we guarantee:
Fresh Stock: Correctly stored to prevent flux degradation.
Fast Logistics: Quick shipping to Kuala Lumpur, Selangor, Johor, and East Malaysia.
Technical Support: Help determining the right electrode for your dissimilar metal combinations.

What does "E309L-16" mean? "E" stands for electrode, "309" refers to the alloy type (22% Cr, 12% Ni), "L" indicates extra-low carbon for corrosion resistance, and "-16" denotes the rutile-type coating suitable for AC and DC currents.
Can I weld stainless steel to mild steel with STAINARC 309L? Yes. This is the primary application for this electrode. It provides a tough, crack-resistant joint between dissimilar ferrous metals.
Is Chiyoda 309L suitable for vertical welding? Yes, it is an all-positional electrode, though it is not recommended for the vertical-down position.
