DIPTI METAL INDUSTRIES
Leading ER318 TIG Rod Stockist, ER318 Supplier & ER318 Exporter in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the primary ER318 Supplier and ER318 Stockist of Niobium-stabilized stainless steel welding consumables in Mumbai, India. ER318 is an advanced molybdenum-bearing filler metal specifically stabilized with Niobium (Columbium) to prevent intergranular chromium carbide precipitation. This makes it the definitive choice for welding matching base metals like Type 316Ti that are subject to high temperatures (up to 800°C) in corrosive environments. As a premier ER318 Exporter, we supply certified TIG rods to chemical processing plants, refineries, and exhaust system manufacturers across 75+ countries.
🏭 Strategic Stability for High-Temperature Corrosive Service
As a leading ER318 Supplier in Mumbai, we cater to the most demanding industrial sectors. ER318 filler metal's primary advantage is the presence of Niobium, which reacts with carbon more readily than chromium. This "stabilization" ensures that chromium remains in solution to provide full corrosion resistance even after the thermal cycles of welding and service. It is indispensable for equipment in the chemical and petrochemical industries that operate continuously at elevated temperatures.
The ER318 Technical Edge
- Prevents intergranular corrosion in the heat-affected zone (HAZ)
- Superior creep-rupture strength at high temperatures
- Excellent resistance to pitting and crevice corrosion
- Smooth arc performance and high-quality weld deposits
Critical Industry Solutions
- Petrochemical: High-temperature reactors and vessels.
- Chemical: Production of acids and pesticides.
- Refineries: Flare stacks and heat exchangers.
- Automotive: High-performance exhaust systems.
