Esab 63342520L0 Stick Electrode Ok 63.34 E316L-16

Product Description

The ESAB 63342520L0 is a rutile-coated manual metal arc (MMA) stick electrode classified E316L-16, designed for welding 19Cr 12Ni 3Mo austenitic stainless steels of similar composition. This is the OK 63.34 formulation, engineered specifically for vertical down welding positions. It produces beads with a clean finish and solid tie-in profiles at the joint edges, reducing post-weld cleanup time. ESAB supplies this electrode in VacPac packaging — a hermetically sealed, vacuum-packed format that protects covered electrodes from moisture pickup and re-absorption. Each package weighs 1 pound. Welders working on stainless fabrication, piping, and sheet metal applications will recognize this classification and deposit characteristics.

The 63342520L0 is suited for welding austenitic stainless steel base metals with 19Cr 12Ni 3Mo chemistry, including grades such as 316 and 316L. Vertical down capability makes it practical on piping runs, structural members, and sheet applications where positional welding is required. The E316L-16 classification indicates a low-carbon deposit with an AC/DC rutile coating, which supports stable arc starting and consistent slag removal. This electrode is appropriate for use in fabrication shops, field piping crews, and maintenance welding environments where 316L-type filler metal is specified.

Key Features

• E316L-16 classification: low-carbon 19Cr 12Ni 3Mo deposit for corrosion-resistant stainless applications
• Rutile (AC/DC) coating for stable arc characteristics and easy slag removal
• Optimized for vertical down welding position
• Produces smooth bead finish with good tie-in to joint edges
• VacPac hermetically sealed vacuum packaging protects electrodes from moisture absorption
• Minimum order quantity of 9 units per package carton

Compatibility

Designed for MMA welding of austenitic stainless steels with 19Cr 12Ni 3Mo composition, including 316 and 316L base metals requiring an E316L-16 classified filler deposit.

Installation Notes

Installation and use should be performed by a qualified welder or welding technician familiar with stainless steel MMA procedures. Verify base metal chemistry and joint design before selecting electrode diameter and heat input parameters. Store electrodes in their VacPac packaging until immediately before use to prevent moisture contamination; re-dry per applicable WPS or manufacturer guidance if packaging integrity has been compromised. Follow applicable welding procedure specifications (WPS) and any governing codes such as AWS D1.6 for structural stainless applications.
