Import Tips

Provide mill test certificates verifying carbon <0.20%, nickel >0.3%, molybdenum content, and copper plating thickness to confirm classification

Ensure wire diameter documentation (≤1.6mm) and proof of suitability for electric arc welding, such as AWS specifications

Avoid misclassification as carbon steel wire by highlighting alloy composition; common pitfall is incorrect carbon analysis
