Studies on characterization of conventionally Melted nitrogen alloyed martensitic stainless Steel in the cast and forged conditions

Abstract

newlineNitrogen Alloyed Martensitic Stainless Steel NAMSS is a new newlineclass of material for aero automobile nuclear corrosive and wear resistant newlineapplications Specialty of NAMSS is high hardness without compromising newlinetoughness due to nitrogen Nitrogen is an interstitial element The main difficulty in production newlineof NAMSS is the solubility of nitrogen Therefore NAMSS were produced newlineusing different advanced technology such as AOD VOD VIM VAR PESR newlineHIP etc A common limitation of various techniques is that they have to be newlineprocessed in controlled atmospheric conditions with specialized equipment newlinewhich is highly expensive Conventional high frequency induction melting can be opted as a newlinebetter choice to overcome the above stated limitation because of its ease of newlineoperation when supported by proper alloy design and process control The newlinework involved in this research is production and characterization of NAMSS newlinein cast heat treated forged and heat treated condition newline newline
