source for L6

This was direct to me from UDDEHOLM for their UHB-15N20
for comparison.

UDDEHOLM bandsaw blade steel nominal chemical composition
over 1,2mm thick will be UHB-15N20
C: 0,75% Si: 0,30% Mn: 0,40% P max: 0,020% S max: 0,010% Ni: 2,0%

the reason for the 15n20 they use is for the toughness needed for the bending the blades take at those thickness .

The first Band steel I was selling I was told by my supplier that it was L6.
now I get the UDDEHOLM marked stuff so I know, it's 15N20..

I should think as much as these commercial blades cut (ripping) in a days time
with the toughness with the 2.0 Ni added it should be a great steel for a sword..

Kevin. what's your view on why you use the L6 ( one or two versions of it..)
rather than the 15N20?
 
Kevin has mentioned this - the 15N20 is like 1075 + Ni . Simpler in chemistry and simpler to handle than the more complex L-6.
 
When Republic Steel was still in business they would call L6, 4370. Even though 4370 wasn't an ASTM designation they would put it through their mill this way.

I personally love 15n20, it is a joy to work with and makes a killer pattern weld when mixed with 10XX steel, but they don't make it thick, thus I don't use it. I preffer my starting layers in pattern welding to be at least 1/2" thick. In pattern welding compression is everything, thus the greater your mass the great the compression potential, the longer youe pice hold it's heat and the exposed less surface area versus volume you have. Of course none of this applies if you don't have a hammer big enough to do massive billets.

I also, like to work with steels that respond well to heat treating in salts in order for me to be the control freak that I am. Talk those folks into making soem 1/4" or better stock and I will grab some;) .
 
kevin what do you think about the "grane" steel? would it be a good choice for a sword. how do you think it would perform compared to crucibles L6, if grane is all i could get? (as a substitute)

I'll see if If can yank the industry some and get some moving :D
 
i had a look at uddeholmstrip.com and it says they only make up to 4mm but i also read this:

SIZE RANGES: Standard ranges of widths and thicknesses are shown here. Limitations are due to production and property combinations. Combinations of width and thickness outside the marked limits are also available in certain cases. We shall be pleased to hear from you for a detailed discussion.

maybe someone could convince them to do a batch of 1/4 or thicker, i mean they want to sell steel and probably quite alot of people would be interested
