Bohler DMO-IG ER70S-A1: Unleash the Strength and Resilience for Your Toughest Welds
For those critical projects demanding unwavering performance, the Bohler DMO-IG ER70S-A1 Creep Resistant Steel TIG Rod steps up to the challenge. This premium TIG welding consumable delivers exceptional strength, crack resistance, and high-temperature tolerance, making it the ideal choice for the below applications.
Uncompromising Performance:
- Superior Creep Resistance: The DMO-IG ER70S-A1 boasts a 0.5% molybdenum alloy that provides exceptional resistance to creep deformation at elevated temperatures, up to 550°C (1022°F). This ensures your welds retain their strength and integrity over extended periods, even in demanding thermal applications.
- Enhanced Crack Resistance: The optimised composition minimises the risk of cracking during welding, reducing rework and ensuring reliable, high-quality welds
- Exceptional Toughness: The DMO-IG ER70S-A1 delivers a very tough weld deposit, making it perfect for applications requiring superior impact resistance and durability
- Ductility Across Temperatures: This TIG rod maintains excellent ductility across a wide temperature range, from -30°C (-22°F) to +500°C (932°F), accommodating for potential thermal contraction and expansion without compromising weld integrity
Features
- Available in industry-standard diameters: 1.6mm, 2.4mm, and 3.0mm for optimal weld pool control and versatility
- Copper coated for smooth feeding and enhanced arc stability
