Product Description
AWS A5.21 ERCoCr-A Stellite bare rod/Stellite 6 hardfacing cobalt base welding wire
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.
Chemical Composition of the deposited metal
Electrode specification and reference current (AC or DC+):
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.
