General Description

AS P-312 is a rutile coated electrode. It gives a filler metal of the Cr-Ni type. 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.

Applications

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.
