Frequently Asked Questions
For joining dissimilar metals, ER309 and ER309L are highly recommended due to their excellent heat and corrosion resistance. For more challenging combinations, ER312 offers low crack sensitivity.
'L' stands for Low Carbon. These grades reduce the risk of carbide precipitation during welding, significantly enhancing resistance to intergranular corrosion.
The increase in Silicon (Si) content improves the fluidity of the molten metal and the overall operability of the arc, resulting in a smoother weld bead and easier application.
ER310 is ideal for high-temperature resistance (25Cr-20Ni), while ER347 is specifically suited for heat-resistant steel due to the addition of Niobium (Nb).
Yes, ER410 is specifically designed for 410 or 420 series stainless steel and is widely used in petroleum refining and the chemical industry for surfacing repair and oxidation resistance.
While both offer corrosion resistance, ER317 contains higher Molybdenum (Mo) content and lower carbon, providing superior strength and protection against intergranular corrosion at higher temperatures.
