From their website "Steel: Burgon Tool Steel, Optiplate-XM The finest ground and stress relieved resulfurized plate in the world. Case hardenable material, Blanchard ground +.010"/.030" over nominal on thickness and width. www.Burgon.com"
Essentially it is just carbon steel with added sulfur to make machining easier. with that said, carbon steel rusts. it would be a good idea to blue or parkerize the frame after you're done. if not, then you can polish it up and keep it oiled to prevent rust
