Introduction:H13CrMoA low-alloy copper wire, a heat-resistant steel, with the corresponding flux for welding the operating temperature below 520 ℃ heat-resistant steel welding, and excellent weld properties, and weld appearance, easy offresidue and so on.
Application:used in boilers, pressure vessels, oil containers and other alloy steel (15CrMo, 12CrMo, etc.) welding. With the flux such as SJ101, SJ104, HJ250, HJ350, etc..
