  • Optimizing the economic efficiency by micro-drill life improvement during deep-hole drilling in the 212-Valve manufacturing process
    The added cobalt in M35 and M42 creates better thermal properties than regular HSS, thus making it a better option for cutting harder material.
  • Powder metallurgy in India: Historical perspective, present scenario and future outlook
    The plant started operating in 1987, and made HSSs such as M3/2, M35 , T15, T42 and a high cobalt grade of M42 .
