Guns through fire?
Assuming a gun has been through a fire, the wood is destroyed but the steel parts show no signs of melting, can the receiver be properly rehardened or is there a point of no return?

Gun in question is a Marlin 1893, looking to rebuild it.

Thanks, Rob

Melting of steel would take about 2800 F. However ruining the heat treatment would take far less .Springs would be effected beyond about 600 F and other parts about 1000 F.Formation of scale [oxide ] would ruin things like rifling .I would think if the wood has been burned ,which can create tewmperatures of up to 1500 F ,the gun is scrap.

I draw the line at spring tension. If the springs are affected in any way, it is not worth the risk and the gun is scrap / wallhanger / practise mule.

It is a very difficult question, as there are so many variables.

In general, even if the action is some super rare model, it is not worth the money you'll save to put yourself or future generations at risk.

However.... If your 1893 still cycles, and it is for one of the blackpowder cartridges such as 32-40 it -may- be feasible, but if it were chambered in 30-30 then discretion would be the better part of valor and just clean it up for a wall hanger. When you do that make a note, then seal it in the barrel so no one tries to shoot it 50 years from now.

I think I would call Marlin, or somebody like Doug Turnbull, or maybe Pacific Heat Treating, or somebody that knows metalurgy.

There have been a lot of custom guns made by first annealing the steel to a completely soft state to do machining, and then reheatreating the whole thing.

I am a metallurgist that's why I responded !Rob could drive over to my place and I could take a look [not far]. Wink

When are you going to shut the fuck up? You post on topics like this as if you knew something when in reality you don't. You refer to companies you've only read about here.

Annealing is a controlled process, a fire is not.

I'm shocked you didn't ask for pictures.

I feel compelled to come to his defense IN THAT he may actually know something about fire damage.

Mete, thanks for the offer but I don't have the parts. They have been offered to me for a restoration project I'm contemplating.

Where abouts are you, in CT?


Thanks, Rob
