説明
特徴
Provides a fully austenitic weld metal and is therefore somewhat more sensitive to hot cracking than 316 grades. Welding should be performed with low heat input, interpass temperature and dilution with parent metal.
アプリケーション
It is suitable for joining and surfacing of matching / similar heat resistant steels / cast steel grades, ferritic chromium steels, 14 %-Mn steels.
使用上の注意
1. Use 100% CO₂ shielding gas.
2. Use DC(+) polarity.
3. Trailer Shield is required to ensure the weld pool completely shield until solidi ication is complete and no porosity problem.
4. To get enough penetration in the down hand welding position recommend maintaining a higher welding speed.
