Valve rod D582 D582 D582 valve stainless steel valve rod welding electrode valve electrode wear D582 D582 efficient stainless steel welding electrode valve sealing surface electrode wear resistant surfacing electrode welding rod electrode wear resistant surfacing electrode 

 Description: D582 is a type of titanium coating Ca-efficient stainless steel welding electrode valve sealing surface. Efficiency as high as 120%, good welding, resistance to high current (higher than ordinary stainless steel electrode -20% 15%), drug-free skin redness cracking, good resistance to intergranular corrosion, AC and DC, for welding, fillet welding. 

 Uses: valve sealing surface surfacing. 

 Welding metal chemical composition: (%) C ≤ 0.10 Si ≤ 1.00 Mn2.50 Cr ≤ 18.00 other Ni ≤ 8.00 

 Surfacing layer hardness: HRC ≥ 170 

 Reference current: electrode diameter (mm) 3.2 4.0 5.0
