Weld Star ER 100S-G Wire [15kg Spool]

The Weld Star ER 100S-G is a high strength, copper coated solid MIG wire alloyed with Nickel, Chromium, and Molybdenum (NiCrMo). It is specifically engineered for welding fine grained steels used in critical structural applications where both high mechanical loads and sub-zero temperatures are a factor.

This alloy is renowned for its extreme crack resistance and its ability to maintain high impact strength (50 J) at temperatures as low as -50°C. Part of the premium "Green Wire" range, it is manufactured from high purity virgin raw materials to ensure consistent metallurgical quality and X-ray clear welds. Whether you are fabricating heavy transport chassis, bridges, or mining equipment, ER 100S-G provides the reliable plasticity and strength required for high stakes engineering.

Key Features

Sub-Zero Reliability: Maintains critical impact toughness down to -50°C, making it suitable for arctic conditions and high altitude structures.

Extreme Crack Resistance: Formulated to handle the stresses of high strength fine grained steels like Weldox 500 and S550.

High-Purity "Green Wire": Sourced from specialised mills using virgin raw materials to eliminate contaminants and ensure consistent feeding.

Superior Feedability: Precision layer wound on 15kg D300 spools for snag free performance at high wire feed speeds.

Versatile Applications: The preferred choice for shipbuilding, railway transport, mining machinery, and bridge building.

High Mechanical Properties: Delivers a typical tensile strength of 730 MPa and a yield of 640 MPa.
