Kobatek 352
gENERAL DESCRIPTION
Kobatek 352 has a manganese alloyed stainless steel deposit containing Cr/Ni/Mn/Mo which is a work hardening alloy. It is used for build-up applications and cushion layers prior to harder overlays, and for a wide range of steel, low alloy steel and 12-14 % austenitic manganese steel components subjected to severe impact combined with high pressure. Steel deposit will also resist a wide range of corrosive conditions and cavitation.
Deposits exhibit a smooth even shaped bead, high metal recovery rates and ease of slag removal. The electrode can be deposited in contact with the workpiece.
