DIPTI METAL INDUSTRIES
Leading ER308Si TIG Rod Stockist, ER308Si Supplier & ER308Si Exporter in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized ER308Si Supplier and the primary ER308Si Stockist of High-Silicon Stainless Steel Welding consumables in Mumbai, India. ER308Si is a specialized variant of the standard 308 filler metal, engineered with a higher Silicon content (0.65% to 1.00%). This technical enhancement significantly improves arc stability and weld pool fluidity (wetting action), making it the preferred choice for high-speed automated welding and projects requiring an aesthetic, smooth bead appearance. As a premier ER308Si Exporter, we supply certified TIG rods to automotive plants, kitchenware manufacturers, and pharmaceutical equipment fabricators across 75+ countries.
🏭 Strategic Advantage of ER308Si High-Silicon Filler
As a specialized ER308Si Supplier in Mumbai, we address the demand for high-efficiency welding consumables. The elevated Silicon level in ER308Si acts as a deoxidizer and reduces surface tension in the molten weld pool. This allows the filler metal to flow more easily into the joint edges, reducing the risk of cold laps and undercuts. It is specifically designed for welding Type 304, 304L, 321, and 347 stainless steels where productivity and bead aesthetics are critical.
The ER308Si Technical Edge
- Improved wetting action for faster travel speeds
- Minimal spatter and smoother weld bead transition
- Excellent arc stability even at low current settings
- Higher productivity in both manual and robotic TIG welding
Precision Welding Solutions
- Automotive: Exhaust systems and manifolds.
- Kitchenware: High-finish SS furniture and sinks.
- Pharma: Smooth internal welds for tanks and tubes.
- General Fab: High-speed production of SS components.
