THE CLEANING OF 303 STAINLESS STEEL [PDF]

open access: yes, 2004
The sulfur found on the surfaces of stainless steel 303 (SS303) after nitric acid passivation originated from the MnS inclusions in the steel. The nitric acid attacked and dissolved these MnS inclusions, and redeposited micron-sized elemental sulfur particles back to the surface.

Novel model for calculating the interface heat flux between roller and molten steel/solidified shell during twin-roll strip casting

open access: yesCase Studies in Thermal Engineering
During the twin-roll strip casting (TRSC) process, molten steel rapidly cools on the copper roller surface, forming a sub-rapid solidified shell. The distribution of thermal resistance at the roller/steel interface is a critical factor influencing ...
