DIPTI METAL INDUSTRIES
Leading ER330 TIG Rod Stockist, ER330 Supplier & ER330 Exporter in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the primary ER330 Supplier and ER330 Stockist of premium heat-resistant welding consumables in Mumbai, India. ER330 is an elite austenitic filler metal containing approximately 35% Nickel and 15% Chromium. It is specifically engineered to provide exceptional resistance to carburization, nitriding, and oxidation in environments reaching temperatures up to 1200°C. As a premier ER330 Exporter, we supply certified TIG rods to heat-treatment furnace manufacturers, quenching plant operators, and heavy chemical processing units across 75+ countries.
🏭 Strategic Stability for Industrial Heating Equipment
As a leading ER330 Supplier in Mumbai, we address the unique thermal challenges of the metallurgy industry. ER330 filler metal is designed with a high silicon content (approx. 1.25%), which significantly enhances its ability to resist carburizing and nitriding atmospheres. This makes the weld deposit highly stable during repetitive heating and cooling cycles, preventing the embrittlement often seen in lower alloyed stainless steels. It is the gold standard for welding Type 330 stainless steel base metals.
The ER330 Technical Edge
- Exceptional resistance to thermal shock and cycle fatigue
- Highly resistant to carburization in furnace atmospheres
- Superior oxidation resistance up to 2100°F (1150°C)
- Maintains fully austenitic structure for long-term ductility
Furnace & Quenching Solutions
