Welding wire with high alloy content and high ferrite ratio which allow it to benefit from extreme tolerance to hot cracking and to dilution with a wide range of base materials. Preheat can often be avoided or minimised.
The weld deposit workhardens and gives good wear and friction resistance. Examples: Welding stainless steels of similar composition or ferritic stainless steels. Joining stainless steels to mild and low-alloyed steels. Buffer layers before hardsurfacing. Maintenance on « hard-to-weld steels ». Welding high carbon hardenable steels, of known or unknown composition and generally most of steels subject to cracking such as tool steels, manganese steels, spring steels and high-speed steels.
