Weld Star ER 310 Stainless Wire [15kg Spool]

The Weld Star ER 310 is a high alloy austenitic stainless steel MIG wire specifically engineered for applications subject to extreme thermal stress. With a high Chromium (26%) and Nickel (20%) content, this wire provides exceptional resistance to oxidation and scaling at working temperatures up to 1000°C.

Commonly referred to as "25 20" stainless wire, ER 310 is the industry standard for fabricating and repairing industrial furnaces, annealing chambers, and heat exchangers. It is a fully austenitic alloy, offering superior structural integrity at high temperatures. Precision layer wound on 15kg D300 spools, it ensures the smooth, consistent wire feeding required for critical welds in boiler parts, fused salt treatment installations, and high heat chemical processing equipment.

Key Features
