Leading ER320 TIG Rod Stockist, ER320 Supplier & ER320 Exporter in Mumbai, India

Dipti Metal Industries (A KMR Group Company) is the primary ER320 Supplier and ER320 Stockist of specialized high-nickel stainless steel welding consumables in Mumbai, India. ER320 is the definitive filler metal for welding Alloy 20 (UNS N08020), also known as Carpenter 20. Containing high amounts of Nickel, Chromium, and Copper, and stabilized with Niobium, it is specifically engineered to provide exceptional resistance to hot sulfuric acid and stress corrosion cracking. As a premier ER320 Exporter, we supply certified TIG rods to chemical processing giants, pharmaceutical plants, and high-spec fertilizer units across 75+ countries.

๐Ÿญ Superior Resistance for High-Acid Chemical Processing

As a leading ER320 Supplier in Mumbai, we address the critical need for weld integrity in environments where standard stainless steels like 316L fail. ER320 filler metal creates a weld deposit that resists the "hot acid" attack, making it indispensable for chemical tankers and process piping. Its unique Niobium stabilization prevents intergranular corrosion, ensuring that the welded joint maintains the same mechanical and chemical properties as the Alloy 20 parent metal.

The ER320 Technical Edge

  • Highest resistance to sulfuric acid and boiling chemicals
  • Exceptional protection against Stress Corrosion Cracking (SCC)
  • Low magnetic permeability even after welding
  • Excellent puddle control and bead appearance

Critical Industry Solutions

  • Chemical: Sulfuric acid pickling tanks and piping.
  • Pharma: High-purity reactors for corrosive reagents.
  • Food: Equipment for processing high-acid foods.
  • Oil & Gas: Scrubbers and gas handling components.
