Product Description

C276 welding wire (ERNiCrMo-4) is a premium nickel-molybdenum-chromium alloy filler metal designed for demanding welding applications. It provides outstanding resistance to strong oxidizing and reducing agents, chloride-induced corrosion, and a wide variety of aggressive chemicals including hydrochloric, sulfuric, and phosphoric acids.

This wire is ideal for welding Hastelloy C-276 base metal, as well as for dissimilar metal welding. It is used in highly corrosive environments such as chemical processing, marine systems, and flue gas scrubbers.

Key Features

• Superior corrosion resistance in both oxidizing and reducing environments

• Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking

• Good mechanical strength and metallurgical stability

• Smooth arc and low spatter during welding

• Suitable for both TIG and MIG welding applications

• Compatible with dissimilar metal joints

Typical Applications

• Chemical reactors and process vessels

• Acid storage tanks and transfer systems

• Marine equipment exposed to seawater

• Heat exchangers and pressure equipment

• Flue gas desulfurization (FGD) systems

• Pharmaceutical and pollution control equipment
