D557 valve welding electrode line GBEDCrNi-C-15 Description: D557 is a low hydrogen sodium type coating of CrNiSi valve welding electrode, welding of metal depend on a large number of silicon intensive, get austenite ferrite, with the aging time increased, hardness and abrasion resistance are further improved performance, deposited metal has good corrosion resistance, oxidation resistance and corrosion resistance, DC reverse. Uses: for temperature lower than 600 â„ƒ high-pressure valve sealing surface of the surfacing.

D577 valve welding electrode line GBEDCrMn-C-15 Description: D577 is a low hydrogen sodium type coating, chrome-manganese steel core valve welding electrode. DC reverse, metal welding-type high-Cr-Mn austenitic steel, it is a significant effect of work hardening, has a good anti-abrasion performance, in a certain temperature hardness, good thermal stability, such as cooperation with D507Mo Use, availability of good anti-abrasion performance, good crack resistance of the electrodes, welding process is simple, from time to preheat welding, weld without heat treatment, welding metal cutting performance is good. Uses: used in welding temperature below 510 â„ƒ in temperature and high pressure valve sealing surface, such as in the valve in conjunction with D507Mo life higher. Valve welding electrode for use: the implementation of GB984-2001 standard surfacing in the workpiece surface or the edge of the deposited layer of wear, corrosion, heat and other properties of metal welding process. Repair and improve parts of life, the rational use of materials, improve product performance, reduce costs with significant economic benefits. Surfacing work and working conditions are very complex, welding must be selected according to different requirements of the appropriate electrodes. Different workpiece and welding electrodes welding technology to be different in order to obtain satisfactory welding results.
