D502 valve surfacing electrode is in accordance with GB EDCR-A1-03 Description: D502 is ti-Ca coating type 1Cr13 valve surfacing electrode, ac-DC dual use, good welding process. The surfacing metal is 1Cr13 semi ferrite high chromium steel. The surfacing layer has the characteristics of air quenching, generally does not need to undergo heat treatment, uniform hardness, can also be annealed at 750-800℃, when heated to 900-1000℃ air cooling or oil quenching, can be re-hardened. Purpose: This is a universal surfacing electrode, used for surfacing of carbon steel or alloy steel shafts and valves whose working temperature is below 450℃.
D507 valve surfacing electrode in accordance with GB EDCR-A1-15 Description: D507 is low sodium hydrogen coating 1Cr13 valve surfacing electrode, using DC reverse connection. The surfacing metal is 1Cr13 semi ferrite high chromium steel. The surfacing layer has the characteristics of air quenching, generally does not need to undergo heat treatment, uniform hardness, can also be annealed at 750-800℃, when heated to 900-1000℃ air cooling or oil quenching, can be re-hardened. Purpose: This is a universal surfacing electrode, used for surfacing of carbon steel or alloy steel shafts and valves whose working temperature is below 450℃.
D507Mo valve surfacing electrode in accordance with GB EDCR-A2-15 Description: D507Mo is a 1Cr13 valve surfacing electrode with low sodium hydrogen coating. The surfacing metal is 1Cr13 semi ferrite high chromium steel. The surfacing layer has the characteristics of air quenching, and the surfacing metal has high hardness at medium temperature, good thermal stability and erosion resistance. If used in conjunction with D577 electrode, good abrasion resistance can be obtained. Surfacing technology is simple, no preheating before welding, no heat treatment after welding, using DC reverse welding. Purpose: For surfacing welding operating temperature below 510℃
