Yes and no... you can use any steels or metals that will stick together to make a cosmetic damascus or makume but to make something that will be used for an edged tool i would say no less than 6 points of carbon ie 1060, so say 1084,1095, 15n20 high nickel shinny, s2 as a 15n20 replacement... for edges high carbon... from there experiment

Yang bin, hunan valin steel. prior to 2008 iron ore was seen as a niche and opaque commodity. the benefits of iron ore indexation have encouraged evolution in other steel derivative markets such as scrap, lump, rebar and hot rolled coil. phillip killicoat, goldman sachs. we rely on what platts does.
Ball or rod mills crush and grind the mined ore to fine particles that may be only microns 10-3 mm in diameter, releasing molybdenite from the gangue worthless rock.
The grinding mills on the right reduce rocks the size of soccer balls to the size of gravel. further ball milling reduces the material to the consistency of face powder.
The milled oregangue powder is mixed with a liquid and aerated in the flotation step. the less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. flotation separates the metallic minerals from the gangue this way and in the case of copper molybdenum ores separates molybdenite from copper sulphide.
The resulting mos2 concentrate contains between 85 and 92 mos2. further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.
