WELDING ROD E138MO (E309 LMo) RODS 2.5MM

Product Description

The WELDING ROD E138Mo (E309LMo) 2.5MM is a low-carbon stainless-steel covered electrode designed for welding stainless steels to unalloyed and low-alloy steels, as well as other dissimilar-metal applications. The E309LMo classification provides a chromium-nickel-molybdenum weld deposit, with molybdenum contributing to improved corrosion resistance and suitability for demanding stainless-steel applications.

The 2.5mm diameter is suitable for controlled welding and fabrication work. Comparable E309LMo 2.5mm electrodes are commonly supplied at approximately 50–100 amps, depending on the electrode formulation and welding conditions.

Pricing is based on per kilogram.
