Description
Characteristics:
LKT-80B2 with 12.5%Cr and 0.5%Mo, is designed for welding low-alloy steels with high tensile strength and creep-resistance steels such as ASTM type A199-76, A200-75, A213-76d, A335-76, A369-76, A387-76.
Applications:
It is suitable for welding of pipelines in pressure vessels and boilers with operating temperatures up to about 500°C
Notes on Usage:
1. Use DC(-) current and 100%Argon gas at proper flow rate.
2. In order not to derogate the weld metal quality from
