THE EFFECT OF CARBIDE PRECIPITATION AND CARBURIZATION ON THE MECHANICAL PROPERTIES OF TYPE 304 STAINLESS STEEL

Technical Report ·
OSTI ID:4108172
An investigation was made of the possible carbide precipitation and carburization of ths surface of stainlless steel in a sodium system. Stainless steel at temperatures as low as 850 gas-cooled F beoomes carburized in sodium contaminated with carbon. Carburization of stainless steel in sodium takes place mainly by grain-boundary diffusion in the 750 to 1000 gas-cooled F temperature range, while at 1200 gas-cooled F and above volume diffusion predominates. Mechanical property tests of type 304 stainless steel which has been carburized in sodium at volume diffusion temperature range show increased strength and reduced ductility. (W.L.H.)
