INCO-WELDR 725NDUR焊丝
INCO-WELDR 725NDUR焊丝AWS A 5.14 ERNiCrMo-15保材质
INCO-WELD 725NDUR焊丝其实就是具有时效强化能力的INCONEL 625填充金属。焊后热处理之后，其具有和INCONEL 625填充金属一样优秀的耐蚀能力，并且具有更高的强度和硬度。油田应用环境要求低合金钢（例如AISI 4130）的应力释放温度范围和INCO-WELD 725NDUR填充金属的时效强化温度范围是一致的。如果焊后退火之后接着进行时效处理，有可能达到更高的强度。
这种焊丝可以用于熔化极气体保护焊和钨极气体保护焊，可以获得又强又硬的焊缝。

The inc-weld 725NDUR welding wire is actually INCONEL 625 filler metal with aging enhancement capability. After welding heat treatment, it has the same excellent corrosion resistance as INCONEL 625 filler metal, and has higher strength and hardness. The temperature range of the stress release temperature of low alloy steel (such as AISI 4130) and the aging of inc-weld 725NDUR filler metal are consistent in the application environment of the oilfield. If the post-weld annealing is followed by an aging treatment, it is possible to reach a higher intensity.
This kind of wire can be used for the welding of gas welding electrode and tungsten gas protection welding.
