clutch fork

I`ll have to modify the clutch fork and make it shorter.
(cause it`s hitting the headers pipe)cut it in two and weld it.
I wonder if any of you guys knows what kind of material the fork is made of
stainless steel or plain iron or.... ?
Had a look at Brewers site but couldn`t find any info of the material.
Any info is greatly appreciated.
