SAF Safer R 600 description: SAFER R600 is a semi-thick basic coated MMA electrode which is easy to use. Typical applications include hard facing subject to m abrasion, e,g civil works and mining equipment, shovel teeth, buckets and crawler shoes. Used for hard facing carbon steels and low alloy steels against abrasion by mineral particles and medium impact and shock. Weld metal hardness 550-650HV which can be ground. Very good resistance to moderate impacts. Preheating to 400C is always necessary, particularly for large work pieces and deposit a maximum of 3 layers. When welding crack sensitive base materials a buffer layer is required using 307 type MMA electrode. Excellent weldability in all postion except Vertical Down. Shall be used in DC- or AC current.
