2.5mm NSB-310-16 Nikko Steel - 310 Stainless Steel MMA Welding Rods
Complete with CE approval these rods conform to AWS A5.4 E309L-16
BS EN 1600: E23 12 L R
2.5mm in diameter these rods are perfect for small jobs within the chemical industry as well as food and brewery industry. Recommended amperage is 65-100 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 310-16 rods can be used in various positions including vertical up.
PA - 1G, 1F, 1FR - Flat Position
PB - 2F, 2FR - Horizontal Vertical Position, Fixed Pipe and Pipe Rotation
PF - 3G uphill, 3F uphill - Vertical Up Position
PE - 4G - Overhead Position
What Nikko Say:
Description:
A unique rutile based flux formulated with very low levels of acid and amphoteric minerals combined 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:
The electrode is used to best advantage on DC+ but is also stable on AC. Weld beads are smooth and slag detachability is good. Because weld metal silicon is low by design to reduce solidification cracking (a feature common to all ferrite free austenitic alloys), the weld profile is more u-convex than normal.
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 using the following materials: ASTM/UNS 310/S31000 CK20 (cast) 310S/S31008 Proprietary materials - Immaculate S (Firth Vickers) 15 RE 10 (Sandvick)
