Product Description

Stellite 190 Electrode Hardfacing Cobalt-based Rod
is a titanium calcium type coating, surfacing electrode with cobalt chromium tungsten alloy cores, should adopt DCRP. Surfacing metal can keep good abrasion resistance and corrosion resistance at 650 degrees.

Applications:
used in the work of 650 degrees Celsius should be able to maintain good wear resistance and a certain degree of corrosion resistance of the occasion; for example, the high temperature and high pressure welding valve and hot shear knife, the impact of hot and cold staggered place.

Notes:
1: before welding electrode must be 150 degrees bake for 1 hours
2: according to the size of the tool and the type of parent material, must be preheated by 300-600 DEG C, should use small current short arc welding
3: after welding should be tempered at 600-700 DEG C after 1 hours and then cold or immediately put the workpiece into the dry and hot sand box or plant ash in the cold, so as not to crack.
