Leading ER383 TIG Rod Stockist, ER383 Supplier & ER383 Exporter in Mumbai, India

Dipti Metal Industries (A KMR Group Company) is the globally recognized ER383 Supplier and the primary ER383 Stockist of super-austenitic stainless steel welding consumables in Mumbai, India. ER383 (matching Alloy 28 / UNS N08028) is a premium filler metal alloyed with high levels of Chromium, Nickel, Molybdenum, and Copper. It is specifically engineered to handle the most aggressive corrosive media, particularly in the production of phosphoric acid and the handling of sour gas (H2S) in oil and gas wells. As a premier ER383 Exporter, we supply certified TIG rods to fertilizer complexes, chemical refineries, and offshore energy projects across 75+ countries.

๐Ÿญ Strategic Resistance for Complex Acidic Environments

As a leading ER383 Supplier in Mumbai, we cater to chemical engineering projects where standard 317L or Duplex fillers fail. ER383's high Nickel (~31%) and Chromium (~27%) content, combined with Molybdenum and Copper, provides exceptional resistance to pitting, crevice corrosion, and Stress Corrosion Cracking (SCC) in halide-containing environments. Its unique ability to resist "wet-process" phosphoric acid makes it the gold standard for the fertilizer industry.

The ER383 Technical Edge

  • Exceptional resistance to phosphoric and sulfuric acids
  • Superior protection against pitting (PREN โ‰ฅ 38)
  • Excellent ductility and mechanical toughness
  • Immune to SCC in high-chloride marine environments

High-Impact Applications

  • Fertilizer: Evaporators and piping for phosphoric acid.
  • Oil & Gas: Downhole tubing and sour gas handling.
  • Pollution Control: Flue gas desulfurization (FGD).
  • Marine: Components exposed to hot, stagnant seawater.
