DIPTI METAL INDUSTRIES
Leading ER385 TIG Rod Stockist, ER385 Supplier & ER385 Exporter in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the primary ER385 Supplier and ER385 Stockist of premium 904L stainless steel welding consumables in Mumbai, India. ER385 (matching Alloy 904L / UNS N08904) is a high-alloy austenitic filler metal with approximately 25% Nickel, 20% Chromium, 4.5% Molybdenum, and 1.5% Copper. It is specifically engineered to provide exceptional resistance to aggressive reducing acids and stress corrosion cracking (SCC) in halide environments. As a premier ER385 Exporter, we supply certified TIG rods to fertilizer complexes, chemical refineries, and pharmaceutical plants across 75+ countries.
🏭 Strategic Resistance for aggressive Reductive Acid Service
As a leading ER385 Supplier in Mumbai, we address the critical need for weld integrity in sectors handling concentrated acids. ER385 filler metal creates a weld deposit that is superior to standard 316L or 317L grades. Its unique Copper addition and high Nickel content ensure that the welded joint can withstand "boiling" sulfuric acid and contaminated phosphoric acid, making it the gold standard for the modern chemical industry and flue gas desulfurization (FGD) systems.
The ER385 Technical Edge
- Exceptional resistance to sulfuric, phosphoric, and organic acids
- High resistance to pitting and crevice corrosion (PREN ≥ 34)
- Excellent protection against Stress Corrosion Cracking (SCC)
- Fully austenitic structure with superior mechanical toughness
Critical Industry Solutions
- Fertilizer: Evaporators and acid transport lines.
- Chemical: High-purity tanks for reducing acids.
- Power Plants: Flue gas desulfurization (FGD) systems.
- Pulp & Paper: Bleaching equipment and wash filters.
