Clifton Steel’s Tensaweld Mang-312 is a gas shielded, flux cored, stainless steel electrode designed to weld in all positions.
The Mang-312 weld wire is formulated to weld dissimilar products such as manganese to Carbon Steel. The high level of ferrite makes the weld metal very resistant to cracking, even when highly diluted. It provides superb performance characteristics in all positions, using either 100% CO2 or 75-80% Ar/Balance CO2 shielding gas. Flat, well-washed beads can be achieved with minimal weaving. Spatter is very low and slag peeling is excellent, minimizing cleanup. Shielding gas mixtures with more than 75-80% argon are not recommended.
Clifton Steel strives to provide our customers with a confident experience while deciding what wire to purchase. That’s why we’ve taken the guesswork out of the buying experience. By developing these wires to compliment our products, we guarantee compatibility when partnered with our material.

important: special ventilation and/or exhaust required
Fumes from the normal use of some welding products can contain significant quantities of components – such as chromium and manganese – which can lower the 5.0 mg/m3 maximum exposure guideline for general welding fume.
Before use, read and understand the material safety data sheet (MSDS) for this product and specific information printed on the product container.
