Admiral steel is listing this steel available (HR 1075/1080)

Has anyone had a chance to work with this?
And would this have similar characteristic as far as heat treating as 1084/1080?
Thanks for your help.
 
If it's listed as hot rolled, but not annealed then it's going to need annealing before you drill, saw or file it.
 
To drill, machine ,saw , you want spheroidized structure NOT pearlite . Whatever they call their HT ,if you have pearlite you'll have problems.If you can't drill or cut it try a sub-critical anneal [1200 F for 2 hours ] to get spheroidized anneal. The hot rolled will also usually have scale[iron oxide] and a decarburized layer beneath that which have to be removed.
 
I did a few swords from Admiral HR1075/1080 a few years back. It was fine.
Since I forged it, I didn't have to worry about the scale or annealing.
If doing stock removal, I would profile the blade, soak in vinegar overnight, and then do a sub-critical anneal to spheroidize it before starting the bevels and drilling holes.

I was wondering why soak in vinegar I imagine that is the pickling part, but not sure what it does.
Thanks
 
I used that steel exclusively for a while. I never had any problems with drilling or cutting it. The scale was a bit annoying but it ground off fairly easy. The only real problem is the hot rolled steel always had a bend in it somewhere
 
About 8-12 hours in a mild acid will soften and remove most of the scale. A hose down while wire brushing it, and a wipe off, will have it ready for the grinder. A gallon of cheap vinegar from Costco is a lot cheaper than ceramic belts.
