ER 308Lsi Welding wires

ER 308Lsi Chemical Composition

ER 308Lsi is a type of stainless steel welding wire designed for welding 18-8 austenitic stainless steels such as 304L and similar grades. The “L” in ER 308Lsi indicates a lower carbon content compared to standard ER308, promoting better weldability and minimizing the risk of carbide precipitation. The “si” signifies the addition of silicon to improve wetting and fluidity during welding. The typical chemical composition (wt%) for ER 308Lsi is as follows:

Carbon (C): Maximum 0.03%
Manganese (Mn): 1.00 – 2.50%
Phosphorus (P): Maximum 0.04%
Sulfur (S): Maximum 0.03%
Silicon (Si): 0.65 – 1.00%
Chromium (Cr): 19.0 – 22.0%
Nickel (Ni): 9.0 – 11.0%
Iron (Fe): Balance
This composition meets the requirements set by the AWS A5.9/A5.9M:2012 standard for stainless steel welding and filler metals. The controlled levels of alloying elements ensure good corrosion resistance, strength, and weldability. As always, it’s important to refer to the specific manufacturer’s data sheet for the ER 308Lsi welding wire being used, as different manufacturers may slightly vary in their formulations and recommended welding parameters.

ER 308Lsi is a stainless steel welding wire that is widely used in various applications where corrosion resistance, strength, and good weldability are crucial. The lower carbon content and the addition of silicon in ER 308Lsi make it suitable for welding austenitic stainless steels such as 304L and similar grades.
