NSS-310

Specification

Description

• NSS-310 is a rutile coated electrode for the welding of 310 austenitic stainless steel
• Deposits 25% Cr - 20% Ni weld metal that offers high temperature ductility and excellent resistance to oxidation at working temperatures of up to 1200ºC
• Produces a smooth and even metal transfer with low spatter
• Features self-releasing slag
• Ideal for both fillet and butt welding applications

Application

• Fabrication of stainless steel structures 
• Assemblies in the chemical, petrochemical, and power industries

Remarks

Prepare and fit the work carefully, cleaning the joints of all foreign material

Proceed with the lowest current possible and short arc without allowing coating to touch molten pool

Short and intermittent welding is preferred to avoid overheating and distortion

Avoid excessive weaving

Discard exposed core wire by striking or scratch welding on a scrap plate until exposed wire is consumed

Use dry electrodes to prevent blow hole in deposit

If necessary, re-dry at 300ºC for 2 hours before use
