Description
Compatible Base Materials
ER316L is a high-quality stainless steel TIG filler designed for welding corrosion-resistant steels, making it ideal for applications such as:
- Austenitic Stainless Steels: AISI 316, 316L, 304, 304L
- Marine & Offshore: Shipbuilding, boat components, and offshore structures
- Food & Beverage Industry: Processing equipment, tanks, and hygienic welds
- Pharmaceutical & Chemical Plants: Piping, vessels, and equipment exposed to aggressive chemicals
- Pulp & Paper Industry: Equipment exposed to corrosive process fluids
- Cryogenic Applications: Equipment operating at extremely low temperatures
Standards & Specifications
- EN ISO 14343-A: G 19 12 3 L
- AWS A5.9: ER316L
Typical Mechanical Properties
- Tensile Strength: 550-650 MPa
- Yield Strength: 420 MPa
- Elongation: >30%
- Impact Strength: >80 J at -196°C
Key Features & Benefits
✅ Low Carbon Content (L Grade): Minimizes carbide precipitation and prevents intergranular corrosion
✅ Molybdenum Addition (2-3%): Provides exceptional resistance to pitting and crevice corrosion
✅ Excellent Corrosion Resistance: Superior performance in chloride-rich and acidic environments
✅ Cryogenic Toughness: Maintains ductility and impact strength at extremely low temperatures
✅ Smooth Feeding Performance: Optimized for TIG welding with consistent wire feeding
Recommended Shielding Gases
- TIG Welding: EN ISO 14175 – I1 (Pure Argon)
- For Thicker Materials:
- M12 (Argon + 1-5% CO₂) – Improved penetration for thicker sections
- M13 (Argon + 1-3% O₂) – Enhanced wetting and bead appearance
Please note the rod length in the description above.
Arc Electrode rods (rough finish coating) are 300mm in length.
Tig filler rods (non arc) are sold in two formats;
- Packs of (x10, x20, x30, x40, x50, x100) are cut down from trade 1m lengths to 333mm. This is to reduce postage costs.
- 1kg, 2.5kg, 5kg are 1m, 1000mm original length.
Our prices include free shipping to the standard Royal Mail boundary postcodes (includes IOM, highlands, remote islands)!
Sorry we can’t afford the same to those outside this region.
