Description:
CHR266
is a potassium low
hydrogen type hardfacing welding rod. The deposited metal shows a
satisfactory capability of crack-resistance and abrasion-resistance due to
it contents a few Mo. Hammering the welded metal when it is hot to avoid
tendency of cracking when welding. It is suitable for hardfacing abraded
parts of crusher machines, excavators, bulldozers, switches of railway, etc.
The welding rods should be backed at a temperature around 250℃ for 1 hour
before welding.
