[QUOTE="1660bob, post: 8633, member: 366"] Hi all, controversial subject this one, but as i have discovered that one of my blades is about 3/16-1/4" out of true, i am looking at the possibility of rectification i.e. straightening. :eek: I have contacted a specialist firm in the Midlands, whose core business is heat treatment of alloys, and heating/straightening/re-heat treating of alloy components. I am assured that this can be done, but the process is VERY temperature critical according to the material spec and each grade of alloy has its own temp at which it can be fettled. The information we have suggests that girdraulic blades are made from "L40", (although I have read also"RR56") and forged. Speaking to the chap at this company, he tells me L40 is a cast material, and if the blades are forged then unlikely that is the material used? Can anyone shed any light on the material originally used? [/QUOTE]
