DIPTI METAL INDUSTRIES
Leading ER218 TIG Rod Stockist, ER218 Supplier & ER218 Exporter in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is India's premier ER218 Supplier and the foremost ER218 Stockist of anti-galling stainless steel welding consumables in Mumbai. ER218 (equivalent to Nitronic® 60 filler) is a unique nitrogen-strengthened austenitic alloy with high silicon and manganese content. It is engineered specifically to prevent metal-to-metal seizing (galling) and cavitation in unlubricated environments. As a trusted ER218 Exporter, we supply precision-ground TIG rods to pump manufacturers, hydro-electric power plants, and aerospace fastener engineers across 75+ countries.
🏭 The Superior Choice for Moving Mechanical Assemblies
As a leading ER218 Supplier in Mumbai, we recognize that standard stainless steels like 304 and 316 are prone to galling under friction. ER218 filler metal creates a weld deposit that work-hardens rapidly and provides a low-friction surface, making it the definitive solution for valve stems, wear rings, and expansion joints. Its resistance to cavitation makes it indispensable for components exposed to high-velocity liquid flow.
The ER218 Technical Edge
- Industry-best galling resistance in unlubricated contact
- Superior resistance to cavitation erosion
- High yield strength (nearly double that of 316L)
- Excellent oxidation resistance up to 1800°F
Critical Wear Challenges Solved
- Pump Wear Rings: Prevents seizing during startup.
- Valve Internals: Ensures smooth stem operation.
- Bridge Bearings: Resists slow-motion frictional wear.
- Fasteners: Allows disassembly without thread stripping.
