Weld Star ER 316LSi Stainless Wire [15kg Spool]

The Weld Star ER 316LSi is a premium austenitic stainless steel MIG wire designed for critical applications requiring maximum corrosion resistance. The "L" (Low Carbon) designation ensures minimal carbide precipitation, protecting the weld against intergranular corrosion without the need for additional stabilisers.

Formulated with 2.5% Molybdenum, this wire provides exceptional resistance to pitting and "creep" in halide and acidic atmospheres, making it the definitive choice for marine engineering, chemical processing, and chlorinated environments. The increased Silicon (Si) content significantly improves weld pool fluidity, resulting in a smooth, aesthetically pleasing deposit that requires minimal post weld clean-up. Precision layer wound on 15kg D300 spools, this wire is engineered for the high feed reliability demanded by professional fabricators.

Key Features

Molybdenum Alloyed: Provides essential protection against pitting and corrosion in marine, acid, and chlorinated media.

Versatile Diameter Range:

- 0.8mm: Ideal for thin walled pipework and sheet metal.

- 1.0mm & 1.2mm: The industrial standard for heavy duty tanks, architectural structures, and food processing plant.

High Silicon Fluidity: Enhanced silicon levels ensure a stable arc and a "wet" puddle that flows beautifully for a flat, smooth bead.

Low Carbon (316L): Reduces the risk of intergranular corrosion, ensuring long term structural integrity in harsh environments.

Temperature Resistant: Suitable for service temperatures up to 400°C.

Marine & Food Grade: Widely used in the manufacture of hot water tanks, roofing, food processing machinery, and chemical vessels.
