Metal & Flux Cored Wire
E81T5-B6C Cr-Mo Flux Cored Welding Wire
E81T5-B6C is a Cr-Mo low alloy steel flux cored welding wire classified under AWS A5.29/A5.29M in the supplied inspection report. The tested 1.2 mm wire uses CO₂ shielding gas and contains 5.2% chromium and 0.50% molybdenum. It is designed for specified Cr-Mo steel welding applications where the required classification and weld metal properties are confirmed. Check base metal compatibility, welding procedure and heat treatment requirements before use.
Product Overview
E81T5-B6C is a Cr-Mo low-alloy steel flux cored welding wire classification stated in the supplied inspection report. The reported deposited metal contains 5.2% chromium and 0.50% molybdenum, indicating a composition within the approximate 5Cr-0.5Mo alloy range.
For buyers sourcing Cr-Mo flux cored welding wire, the key considerations are the required AWS classification, base metal compatibility, weld metal properties and qualified welding procedure.

Applications and Material Selection
The reported Cr-Mo composition may be relevant to selected heat-resistant steel welding applications. Before using E81T5-B6C, confirm the base metal grade, required filler metal classification, service conditions and welding procedure.
For buyers comparing different Cr-Mo welding wire types, see our ER80S-B6 solid welding wire for P5 and T5 steel. Although both products are associated with Cr-Mo welding, E81T5-B6C and ER80S-B6 are different AWS classifications and should not be treated as direct substitutes.
For broader guidance on alloy grades and consumable selection, read our guide to Cr-Mo welding consumables, grades, materials and applications.
Before ordering, confirm:
- Base metal grade and required AWS classification.
- Required chemical composition and mechanical properties.
- Preheat and post-weld heat treatment requirements.
- Shielding gas and qualified welding procedure.
- Inspection and documentation requirements.
