Stoody 966-G is a molybdenum-tungsten high speed tool steel with a high concentration of uniformly distributed small primary carbides. The presence of the small carbides greatly improve the wear resistance when compared to M-7 tool steel. Stoody 966-G provides wear resistance greater than or equal to that of conventional chromium carbides but does not cross check when proper preheat and welding procedures are used. It is recommended for parts where cross checking is undesirable. It can be applied crack free without preheat on carbon, 300 series stainless and manganese steels. Preheat and interpass temperatures shall be determined by base metal requirements. Post weld heat treatment may be required for other base metals. The deposit will crack on cast irons.
