jcornell Posted February 10, 2011 Share Posted February 10, 2011 I have picked up some free steel. It has the following composition: C < or = 0.03 S < or = 0.0005 P < or = 0.005 Si < or = 0.10 Mn < or = 0.10 Cr < or = 0.50 Ni = 18-20 Mo = 4-5 Cu < or = 0.30 Sn < or = 0.005 Al = 0.05-0 B < or = 0.003 Co = 8-13 Ti = 0.5-2.0 Ca = 0.005 Zr < or = 0.02 In its first life it was used as a fencing foil (those funny little swords with the rubber button on the end).

MattBower Posted February 10, 2011 Share Posted February 10, 2011 It's a maraging steel. Looks like something from the 18Ni family. http://www.matweb.com/search/DataSheet.aspx?MatGUID=54d654bef4f84c4c886a44290cc5cc3c http://www.imoa.info/moly_uses/moly_grade_alloy_steels_irons/maraging_steels.html http://www.keytometals.com/articles/art103.htm Quote Link to comment Share on other sites More sharing options...
fciron Posted February 11, 2011 Share Posted February 11, 2011 Huh, the wikipedia entry for 'maraging steel' specifically mentions it's use in fencing swords. Cool. (Maybe that's how Matt Bower knew what it was?) http://en.wikipedia.org/wiki/Maraging_steel Quote Link to comment Share on other sites More sharing options...
MattBower Posted February 11, 2011 Share Posted February 11, 2011 Actually, first thing I did was go to MatWeb and do an alloy search using the composition he provided. http://www.matweb.com/search/CompositionSearch.aspx Quote Link to comment Share on other sites More sharing options...
