    Improved Yield Strength of steel with higher carbon content certain???

    I actually talked to the metallurgist at the Steel Mill last night where most of the material we buy is produced… he told me 1018 is common as well in sheet/plate and is the best low cost option for our higher strength requirements. Perhaps the 1018 sheet/plate is only commonly produced at that...

    Improved Yield Strength of steel with higher carbon content certain???

    I like the hardness test... easy and accessible, and good enough for the gist... the problem is this will never happen, except for intervention. You put the material spec on the print so that it covers all bases and forget it. Perhaps I can use the fact that 1018 is not necessarily stronger in...

    Improved Yield Strength of steel with higher carbon content certain???

    I tried a search and found nothing... this seems so basic but I can't get a definitive answer anywhere so hopefully someone here can shed some light on the subject. We primarily make formed and fabricated welded assemblies out of gauge thickness sheet and plate up to 3/8". We use 2 types of...

    No difference in placement orientation of magnet in pocket. It is magnetized through its thickness, but I will try your test to see if there are crowdy zones... I assume steel chips will work? I dont think I have iron particles handy ;-)

    Ahhh I have to post a Cad sketch to a webserver to show on this forum… I can’t do that from work. Is there a way to attach a file that I don’t see? I don’t want to go into too much product detail, but the application is for replacement of fastening hardware… so it is probably an unconventional...

    Oh, I forgot to mention that the force to remove the magnet from the pocket is the same whether it spins freely or if it appears "fixed".

    OK, so my company makes a product where a blade is attached to a backing with a series of neodymium magnets. The backing is zinc plated cast iron, and the blade is steel. The backing has "pockets" that are bored just over the OD of the magnet (.0001-.004”), and just slightly deeper than the...
