ER308L Stainless Steel TIG Filler Rod – 1.6mm, 2.4mm & 3.2mm – 5kg

ER308L Stainless Steel TIG Filler Rod is a premium-quality filler metal designed for professional TIG welding of 304 and other compatible austenitic stainless steels.

Available in 1.6mm, 2.4mm, ER308L is an excellent general-purpose stainless TIG filler for fabrication where good corrosion resistance, clean weld appearance and dependable weld quality are required.

The low-carbon ER308L composition helps minimise the risk of intergranular corrosion caused by carbide precipitation during welding. This makes it a popular filler for stainless steel fabrication across food and beverage equipment, exhaust systems, tanks, pipework and general workshop applications.

Hampdon Industrial TIG filler rods are manufactured for consistent composition and welding performance. Each rod is individually grade marked by stamping or laser engraving for easy identification and traceability.

Supplied in a 5kg pack and securely packaged to help keep the rods clean, straight and protected during storage and transport.

Why Choose ER308L TIG Filler Rod?

ER308L is one of the most commonly used TIG filler metals for welding 18Cr-8Ni austenitic stainless steels, including the widely used 304 and 304L grades.

The “L” designation means low carbon, which helps reduce carbide precipitation and improves resistance to intergranular corrosion in the weld area.

ER308L provides excellent weldability, smooth puddle characteristics and a clean, bright weld appearance, making it an excellent all-round choice for professional stainless steel TIG fabrication.
