产品特性DESCRIPTION

SW·ERNiCrMo-15焊丝用于高强度耐腐蚀镍合金，特别是UNS N7725和UNS N09925的焊接，也用于与钢的焊接和高强度镍铬钼合金表面堆焊。强度达到最大值是，焊后需要进行沉淀淬火，可进行各种热处理。

SW·ERNiCrMo-15 welding wire is used for welding high-strength corrosion-resistant nickel alloys, particularly UNS N7725 and UNS N09925. It is also used for welding to steels and surfacing the surface of high-strength nickel-chromium-molybdenum alloys. When maximum strength is required, post-weld precipitation hardening is necessary, and various heat treatments can be performed.

应用APPLICATIONS

用于焊接处理强腐蚀性介质的设备，如接触硫酸、盐酸、磷酸、醋酸等强酸的反应釜、换热器、储罐及管道。

It is used for welding equipment that handles highly corrosive media, such as reaction kettles, heat exchangers, storage tanks and pipelines that come into contact with strong acids like sulfuric acid, hydrochloric acid, phosphoric acid and acetic acid.
