1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 9 SMC-65 LOW HYDROGEN - LOW ALLOY - HIGH EFFICIENCY HARDFACING ELECTRODE FOR BALANCED RESISTANCE TO ABRASION AND IMPACT LOADING DATA SHEET NO. 128 SPECIFICATION CLASSIFICATION JIS Z3251 DF3C-600-B PRODUCT DESCRIPTION The design emphasis of the chemically basic flux is engineered to ensure that the weld metal hardness levels demanded by the specification are fully met without detracting from the toughness levels associated with this class of alloy. The basic flux containing the appropriate alloying elements and a balanced addition of iron powder is extruded onto a high purity ferritic core wire using a balance of silicates that ensures both coating strength and resistance to moisture absorption. WELDING FEATURES OF THE ELECTRODE The electrode is suitable for both AC and DC and may be used in all positions except vertical down. Arc stability is good as is slag detachability. Weld seams are smooth, evenly rippled and slightly convex in shape. The metal recovery of the electrode is some 120% with respect to weight of the core wire. APPLICATIONS AND MATERIALS TO BE WELDED On high carbon steels H V-250B should be used as a buffer layer. The weld deposit has good resistance to abrasion, under normal circumstances is crack free, and will withstand a reasonable amount of impact loading. Used to particular advantage for : bulldozer blades, crusher jaws, bucket lips and teeth involved in earth moving and mineral crushing. Where the main wear is abrasion, but with some impact resulting from rocks and compacted minerals. Under normal circumstances the weld metal is non-machinable.
