Product Overview
The Hyundai S-312L (S-312.16) Weld All Electrode, 2.6mm is a premium lime-titania type stainless steel welding electrode engineered for high-performance dissimilar metal welding. Renowned for its excellent usability, smooth arc characteristics, and superior weldability, this electrode is a trusted choice among professional welders, fabricators, and industrial workshops working with stainless steel, carbon steel, and low-alloy steel combinations.
With an all-weld metal chemical composition of 29% Chromium – 9% Nickel (29Cr-9Ni), the Hyundai 312L electrode produces a duplex austenitic-ferritic structure with a high ferrite content, delivering outstanding crack resistance and an excellent buffer effect against outer stress — making it ideal for joining metals of different compositions and hardenability.
Key Features & Benefits
- Dissimilar Metal Welding – Specifically formulated for bond welding of dissimilar metals such as stainless steel to carbon steel and low-alloy steel
- High Crack Resistance – Austenitic-ferritic microstructure with elevated ferrite content minimizes solidification cracking
- Excellent Buffer Effect – Absorbs and cushions stress between dissimilar base metals, reducing weld failure risk
- Versatile Applications – Ideal for stainless steel clad welding, underlaying/build-up welding of high-alloyed tool steel, and hardfacing work
- Smooth Arc & Easy Slag Removal – Lime-titania coating ensures stable arc performance, low spatter, and a clean, easy-to-remove slag layer
- Reliable Weld Quality – Consistent bead appearance and mechanical properties suited for demanding industrial applications
