DETAILS
It gives a filler metal of the Cr-Ni type.
Features
- Due to its high tensile and impact resistance, it is used for the joining and build up welding of steels with a high tendency to cracking. It is especially developed for maintenance and repair welding.
- Unalloyed steels, high carbon steels (1.4085 : G-X 70 Cr 29), high alloyed steels, tool steels, spring steels, high speed steels, cast pieces and air hardenable armour steel plates that have poor weldability can be welded with AS P-312.
- Joining of unalloyed or low alloyed steels with stainless steels and build up welding of gears and shafts are among its application areas.
- Generally, there is no preheating requirement before welding. If preheating is necessary, preheating temperature might be less than that required for other electrodes.
- AS P-312 should not be used for the welding of parts that are continuously operating at temperatures exceeding 450°C. Interpass temperature should be controlled in multipass applications.
