Antoine Posted September 3, 2010 Share Posted September 3, 2010 Hi, I just finished a san mai blade made with 203E given to me by a friend... First time I work with this steel. When I polished the blade to a 600 grit I saw something strange in the steel. I etch it in ferric acid and appeared faintly but clearly what looked like a damascus pattern (looks 200 layers)! I talked to my friend and he assured me it is 203E from admiral. What could it be? Is it possible I'm seeing some kind of segregation? I can provide picture if it helps... Thank's, Antoine http://antoinemarcal.wordpress.com Link to comment Share on other sites More sharing options...
Kenon Rain. Posted September 3, 2010 Share Posted September 3, 2010 good ole admiral and their alloy banding.. I really need to place an order from them some time for some.. Link to comment Share on other sites More sharing options...
Sam Salvati Posted September 3, 2010 Share Posted September 3, 2010 the banding should have disappeared after the welding cycles, so it's maybe a product of low temper cycling like normalisations below or right on non magnetic? Let not the swords of good and free men be reforged into plowshares, but may they rest in a place of honor; ready, well oiled and God willing unused. For if the price of peace becomes licking the boots of tyrants, then "To Arms!" I say, and may the fortunes of war smile upon patriots Link to comment Share on other sites More sharing options...

Ty Murch Posted September 4, 2010 Share Posted September 4, 2010 could the alloy banding in admiral's steel be because it is sheared from plate rather than rolled into bars? . Link to comment Share on other sites More sharing options...
kb0fhp Posted December 18, 2010 Share Posted December 18, 2010 I suspect that it more than likely Chinese steel. One of the real problems with Chinese steel is the tendency for low hardenability, uneven grain size and alloy banding. D.
