DIPTI METAL INDUSTRIES
Leading ER307 TIG Rod Stockist, ER307 Supplier & ER307 Exporter in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the primary ER307 Supplier and ER307 Stockist of specialized high-manganese stainless steel welding consumables in Mumbai, India. ER307 is a unique austenitic filler metal containing approximately 6-7% Manganese. It is specifically engineered for "difficult-to-weld" applications, including joining armor plates, austenitic manganese steels (Hadfield steels), and dissimilar metal combinations (stainless to carbon steel). As a premier ER307 Exporter, we supply certified TIG rods to defense contractors, earthmoving equipment manufacturers, and heavy engineering firms across 75+ countries.
🏭 Strategic Welding Solutions for Problem Steels
As a leading ER307 Supplier in Mumbai, we recognize that standard stainless fillers often fail when joining steels with high hardenability. ER307 filler metal provides high crack resistance and extraordinary toughness. The weld deposit is non-magnetic and work-hardens rapidly under impact, making it the definitive choice for wear-resistant cladding and joining parts subject to heavy mechanical stress.
The ER307 Technical Edge
- Exceptional resistance to hot cracking
- Superior joining of dissimilar metal combinations
- Rapid work-hardening properties under impact
- High heat resistance and mechanical toughness
Heavy Engineering Solutions
- Defense: Welding of ballistic armor plates.
- Mining: Joining & repair of manganese steel crushers.
- Earthmoving: Building up wear-resistant parts.
- Railways: Welding of manganese rail crossings.
