Application field
The metal powder cored wire SK STELKAY 21-G is used for crack resistant buildups on structural parts
subject to a combination of compression, impact, abrasion, corrosion and high tem-peratures up to 900° C,
such as running and sealing faces on gas, water, steam and acid fittings and pumps, valve seats and cones for
combustion engines, working parts on turbine and power units, hot working tools with high alternating
thermal load.
Properties of the weld metal
Excellent gliding properties, polishable and tough, non-magnetic.
Hardness of the pure weld deposit: 30 HRC
Weld metal analysis in %
Welding instruction
Clean welding area, preheating to 150 - 400° C, depending on the size of the workpiece and the base material.
Welding with pushing technique, possibly with pulsed arc and approx. 20 mm wire stickout.
