dwilks Posted August 8, 2018 Share Posted August 8, 2018 does anybody know what kind of steel, steel carabiners are made of? I have access to a good amount of retired rescue carabiners and wondering if they are useful for knife blades. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 8, 2018 Share Posted August 8, 2018 Probably not Knifeblades need to be hard to take a really good edge. In steel; hardness is correlated with brittleness. Do you want a brittle carabiner? I would think they are most likely to be a tough medium carbon steel. But like any steel from the scrap stream you are thinking of using TEST IT. Take one heat to above nonmagnetic and quench in a 5 gallon bucket of water---fast! Then try to break it with a hammer wearing PPE! If it shatters then you are in luck; if it breaks only grudgingly or just bends you are not. Note a manufacturer can change the alloy used 3 times a day as long as it meets the strength specs; so no guarantee that any two will be made from the same stuff...

Daswulf Posted August 8, 2018 Share Posted August 8, 2018 And if they are marked with a manufacturer name, or the supplier can tell you, you could try to contact them and ask. Other than that, Thomas' suggestion. Quote Link to comment Share on other sites More sharing options...

I was planning on testing just figured I would throw it out there and see if anybody had some info. didn't think of asking the manufacturer. I'll look into that, and test myself.

I can imagine the sketch in your avatar hanging his head and wearily shaking it. Quote Link to comment Share on other sites More sharing options...
