INCO-WELDR 725NDUR焊絲
INCO-WELDR 725NDUR焊絲AWS A 5.14 ERNiCrMo-15保材質(zhì)
INCO-WELD 725NDUR焊絲其實就是具有時效強化能力的INCONEL 625填充金屬。焊后熱處理之后，其具有和INCONEL 625填充金屬一樣優(yōu)秀的耐蝕能力，并且具有更高的強度和硬度。油田應用環(huán)境要求低合金鋼（例如AISI 4130）的應力釋放溫度范圍和INCO-WELD 725NDUR填充金屬的時效強化溫度范圍是一致的。如果焊后退火之后接著進行時效處理，有可能達到更高的強度。
這種焊絲可以用于熔化極氣體保護焊和鎢極氣體保護焊，可以獲得又強又硬的焊縫。

The inc-weld 725NDUR welding wire is actually INCONEL 625 filler bl with aging enhancement capability. After welding heat treatment, it has the same excellent corrosion resistance as INCONEL 625 filler bl, 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 bl 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.
