Madung bungli galaw ai atsam ningja ni:

• N-gun shayawm ai npu hta daw garan ai hpe ninghkap lu ai atsam
• Katsi ai aten hta ngang grin ai n-gun
• Hkai sun hta jung na matu kam mai ai weldability
• Npu-katsi ai ASME n-gun masa ni a matu hkan sa ai

Sulphur & phosphorus n law ai majaw, nbung katsi ai shara hta notch ngang kang ai lam hpe grau kaja hkra galaw ya ai.

Charpy V-Notch chyam dinglik ai lam gaw LNG hte arctic magam bungli a matu daw garan ai lam hpe ninghkap lu ai atsam hpe madi shadaw ya ai.
