DETAILS
A mild steel self-shielded flux-cored wire designed to provide low temperature impact toughness in a variety of offshore applications.
Eigenschaften
- Premium Offshore Weldability – designed to provide optimal weldability in narrow TKY joints and poor fit up conditions
- Excellent Toe Wash-In – expect fast travel speeds and a flat bead face when using vertical-up or vertical-down welding techniques
- Low Temperature Impact Toughness – meets ABS 4YSA and AWS J classification
- Low Diffusible Hydrogen Levels – meets H8 diffusible hydrogen requirements over a range of humidity levels
- ProTech® Packaging – hermetically sealed packaging for moisture resistance
- Q2 Lot – certificate showing actual deposit chemistry and mechanical properties per lot available online
