NSS-308 is a lime-titania coated stainless steel welding electrode classified as AWS A5.4 E308-16, designed for Shielded Metal Arc Welding (SMAW) of austenitic stainless steels. It deposits an 18% Chromium (Cr) – 8% Nickel (Ni) weld metal that provides excellent corrosion resistance, smooth bead appearance, and minimal spatter. It can be used with AC, DC positive (+), or DC negative (-) current.
Key Features
• Produces high-quality austenitic stainless steel weld deposits (18Cr-8Ni).
• Virtually free from spatter, resulting in cleaner welds.
• Excellent arc stability and ease of operation.
• Superior slag detachability for easier post-weld cleaning.
• Good resistance to corrosion and oxidation.
• Suitable for all-position welding applications.
Typical Applications
• Welding of stainless steel grades 301, 302, 303, 304, 304L, and 321.
• Fabrication and maintenance of:
o Chemical processing equipment
o Food and beverage processing plants
o Pharmaceutical equipment
o Stainless steel tanks and piping
o Architectural and structural stainless steel components
o General stainless steel fabrication works
