Gunsmithing Did I ruin my bolt?

[javy]

Decided to sonic clean my bolt..
Separated the bolt body from the firing pin assembly
Put bolt and firing pin assembly in the sonic cleaner and set for 45 min at 100 degrees
Came back in 40 min and temp was 165 dgrees

The gun is a 1956 model Remington 722
Bolt body was a chrome looking finish as the all are, now is pewter grey
Bolt handle is now antique copper looking
Bolt shroud is pewter grey

Was concerned that solder might turn loose on handle but I could not break it off with my hands.
My real concern is that I might have changed the temper of the bolt lugs.....

Can someone with more metallurgy knowledge than I have or some of you riflesmiths weigh in on this.

Thank you

At 165* I would doubt it but I'll defer to smarter guys.

Not hot enough to change the structure of the steel. Now the finishes, that is a different story.

 

[Spblademaker]

165* F isn’t going to affect the hardness of the steel.

Hell, I bet it would get that hot if it were black sitting out in the Denver summer sun.

What cleaner did you use?

 

[javy]

I believe it is the hornady cleaner.

I kinda like the “new” colors

I made the mistake of putting a die in an ultrasonic bath. Came out looking like you are describing. I polished it with Flitz and it came back to its original color.

Gun parts cleaner or brass cleaner? I have seen brass cleaner create those colors on steel parts.

Make sure you re-oil it too before judging the colors. Depending on the cleaner/solvent used, metal comes out super-dry.

I did something like that, put my wife's blue anodized revolver in the ultrasonic sink with simple green. Took that sucker down to bright metal. Had to get it ceracoted.

Yea you have to be careful, simple green is caustic with AL

It did come out super dry. Oiled them up good.

Max, the cleaner is hornady one shot “cartridge case formula”.

Lesson learned on my part

The one thing I do know for sure, it is “clean”...

Yea, I learned the same lesson with a carburetor and RCBS brass cleaner. The aluminum was fine but all the steel parts turned to a pewter color.

Started using mineral spirits in my sonic cleaner. Works fine for gun parts. No crazy colors yet.

 

[Holliday]

I tried a Ballistol water mix they recommend. No weird colors but did not clean either. I know its blasphemy but I find Ballistol just about useless on firearms.......

 

[Cerwinski]

The "cartridge" formula is acetic acid. Not what you should be bathing gun parts in.

 

[javy]

Thanks for everyone who responded. Long as bolt hardness was not affected then all will be good.
Not worried about the color so much.

Thanks everyone

no effect on the strength. Cosmetic only.
