2.0mm NSB-309L-16 Nikko Steel - 309L Stainless Steel MMA Welding Rods

Complete with CE approval these rods conform to AWS A5.4 E309L-16 
BS EN 1600, JIS Z 3221, E23 12 L R

2.0mm in diameter these rods are perfect for small jobs joining mild steel to stainless steel. Recommended amperage is 35-80 amps and they are sold in packs of 1kg. 

We favour Nikko branded rods for the quality of the weld result as well as how well these rods perform in terms of ease of striking and lower volume of spatter compared to other rods on the market. They may cost slightly more than others but for a good finish these rods prove to be excellent value for money. 

The 309L-16 rods can be used in most positions;
PA - 1G, 1F, 1FR - Flat Position
PB - 2F, 2FR - Horizontal Vertical Position, Fixed Pipe and Pipe Rotation
PC - 2G - Fixed Pipe
PF - 3G uphill, 3F uphill - Vertical Up Position
PE - 4G - Overhead Position

What Nikko Say: 
Description: 
A metallurgically advanced rutile based flux formulated with balanced additions of chemically basic, amphoteric and acid minerals, together with small alloy additions to compensate for arc losses. The flux is concentrically extruded onto a fully alloyed core wire and bound by a blend of silicates that assures both coating strength and resistance to subsequent moisture absorption.

Features of rod:
This unique flux formulation ensures excellent arc stability, ease of initial arc strike and re-strike minimal spatter on AC and virtually none on DC+. The resultant weld seams are smooth, evenly rippled and free from undercut while slag detachability is excellent. Metal recovery is some 103% with respect to core wire weight.

Welding applications: 
Applications for the electrode are to be found in the Chemical, Petro-Chemical and Cryogenic Processing and Storage Industries as well as the Food, Brewery and Pharmaceutical Industries. Transition welds between stainless steel and ferritic steel welding clad plate or as a buffer layer on ferritic steel before completing with a more conventional low carbon austenitic stainless steel, such as 304L.
