If it is pre 64 it will blue, after 1964 the action will not blue.... usually guys blast and nickle plate the action...
I have managed to rust blue a post 64, my understanding is hot blue tends not to work. However i am not sure there isnt more then one type of post 64 reciever material.

Here is my 1974 Winchester 3030 that scar270 did. It has had a rough life so there was some preexisting Pitts in it but the blue took very well.
I read they had some kind of sintered metal for a few years then switched back to steel
It looks pretty pale maybe that one is the sintered metal
Pre-64 (1894-1963) & post-83 (1983-2006) and Mikoru (2010-present) Model 1894/94/94AE (Angle Eject) receivers are forged steel.
Post-64 (1964-82) receivers are made via sintering - a process that's use to form objects from powdered metal.
The 1964-82 sintered receivers were iron-plated so they would accept the various finishes Winchester was offering during those years - "Bluing" (it isn't), Pewter, Gold, Silver, Brass (all commemoratives), Case Colors (M94 Antique), and Black Chrome (NRA Rifle/Musket, M94 Classic & some commemoratives).
I copied and pasted this from another site.
