ROYAL PRIME 91T-8

AWS/ASME: A5.36 E91T8-A2-K2-H8

ROYAL PRIME 91T-8 is a self-shielded flux cored wire designed for high-strength low alloy steels.

Delivers excellent impact toughness at low temperatures.
Designed for structural steel, offshore platforms, and heavy equipment fabrication.
High productivity in out-of-position welding (all-position electrode).
No shielding gas required – ideal for field erection and windy environments.
Hydrogen-controlled formulation (H8) reduces risk of cold cracking.
