COSMAX – 307 R

Classification : AWS : E30716

Characteristics : COSMAX 307 R is a versatile austenltic stainless steel electrode with 19 Cr 9 NI 6 Mn. Excellent deposition efficiency. Weld metal produced shows exceptional crack resistance and high degree of deformability. Good functionablity in rigid assemblies. Stable austenitlc micro structure does not suffer any sigma phase formation.

Applications : Ideally suitable for joining ferritlc to austenitlc steel, armour plates, austenltic manganese steel, heat resistant steel, dissimilar materials for layers etc. COSMAX 307 R is an extermely useful electrode both for buffer Slayers and hard facing. Clutch lugs, conveyors, crusher cones, drag line buckets lips and teeth, crusher hammers & crusher jaws, sizing screens and crousers.
