realistically how long should carbon steel tools last before rusting. would you buy carbon steel tools? or is cr-v the standard?
There are still working spanners from the 1800s.
>>2938963Carbon steel tools should never rust because maintaining them properly is your responsibility. They only rust when you slack off or do something stupid. Clean them, oil them, and use them regularly and rust should never occur.
>>2939013This. Take care of them and use them and they will last forever.
>>2939016Use them for automotive work and you won’t have a problem.
>>2938963Coat them in oil, it's not rocket science
>>2938963this is my grandfathers invention. he never patented it. it has never been cleaned or painted and has floated around in my dads stuff and now mine. it has pretty much never been used. it is over 70 years old.
>>2939016>>2939013>>2938982so is the cr-v branding just a meme then? i'm not arguing just asking what the point is if it's as simple as oiling and forgetting. i keep my tools in a closed space with anti moisture satchels.>>2939107anon, this thing looks wild. can you expand on how it functions? why not wire brush it and restore it?
>>2939107Not bad. Props to him for not falling for the 'iNtElLeCtUaL pRoPeRtY' meme.>>2939177Pretty obvious how it operates, isnt it? If I were anon I'd preserve it as is and hand it down again and not fuck with it.
>>2939177CR-V just means its chrome vanadium steel. That is a stronger and higher quality steel for tools. The rust resistance is a secondary trait.Chrome plated tools are more about being clean and rust free. Good quality chrome plating is highly rust resistant and easy to clean. You will see it a lot for thing that get nasty, like automotive tools. Way less common for things like woodworking.
>>2938963>realistically how long should carbon steel tools last before rusting. would you buy carbon steel tools? or is cr-v the standard?First, there are different “carbon steel” alloys, were the only difference is the carbon percentage, although the processing method can also have a large influence on the finished product, since carbon can get burned off from the surface during hot forging, and can be added by case hardening methods. As for “alloy steels” other than basic carbon steel, one of the main reasons even cheaper manufacturers use these “tool steels” is because basic carbon steels aren’t usually made to the strictest tolerances and testing, even by USA manufacturers, whereas quality manufacturers routinely test alloy steels to verify alloy content on the alloy steels. The exception to this is “third world” manufacturers, were cheating on alloy content is extremely common, as are verification certificates. Even Japanese manufacturers were cheating on alloy content, with the knowledge of the US government, and in China, the issue is way worse. As for specific alloys, preferences usually come down to what is available, the type of tool, the planned processing methods, and how each component works in the finished product. In classic Locking pliers, the jaws would likely be forged from one alloy, maybe a vanadium steel, the bent sheet metal parts would likely be a different alloy, optimal for high tensile sheet metal, maybe a Molybdenum alloy, the springs would likely be subcontracted to a spring manufacturer using an optimal alloy for springs, and the rivets would be made out of an alloy that could be cold riveted. The original vise grips had the jaws braized to the sheet metal handles, and that would be a bronze alloy, so the rivets are just reinforcement that help brazing. Afterwards, the pluers are cleaned and plated, because the plating keeps welding slag from easily sticking to the locking pliers when used as welding clamps.

CR-V is always the standard
>>2938963As long as you oil them after each use with a rag and put them in a container safe from the elements (like a toolbox) they'll last longer than you without any notable corrosion. 3 in 1 oil, wd40, doesnt matter. Tools made of just regular iron are in working shape for centuries doing the same thing.
>>2939107That's a cool invention.
