Ideally suited to the welding of all grades of grey cast iron, particularly thin sections and welds that require highest possible machinability. TYPICAL APPLICATIONS Automotive and truck engine blocks, motor blocks, cylinder blocks and heads, pump housing, transmissions and differential housings, pump and valve housings and the like. SPECIFICATIONS Tensile Strength .......................................55,000 psi Hardness..................................................Ro ckwell B 82-84 WELDING TECHNIQUES Clean weld area of all scale, grease and dirt. Bevel breaks and cracks to 70-90 vee. Use a short to medium arc at the minimum possible amperage for best results. Stringer beads or weaving technique. Peen to relieve stresses. Skip weld to avoid excessive local heat. Remove slag between deposits. Allow castings to cool slowly to room temperature. AWS/ASME 5.15 E Ni - Cl
