fox advertised chromox as chrome nickel vanadium alloy steel but i've never seen the percentages quoted. those who own fox guns should be proud to know fox was way ahead of competing makers in using alloy steel starting 1912 with the 16 and 20 gauge guns. that was years before winchester did the same with its m21. those interested in the winchester's comparison of its alloy steel, properly heat treated, and the same steel case hardened, should refer to that testing in schwand's 21 book. suffice to say the heat treated alloy was way stronger than the same steel, case hardened. now back to bbman's dilemna. he probably has a chromox small gauge receiver, what's he to do now that its annealed? what say our resident metallurgists and mech e's?
