Can Chemicals Cut Through Hardened Steel?

Click For Summary

Discussion Overview

The discussion centers around the feasibility of using chemicals to cut through hardened steel, particularly in reference to depictions in movies. Participants explore various chemical reactions and their effectiveness in this context, including both theoretical and practical considerations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant bets that no chemical can cut through hardened steel as depicted in movies.
  • Another participant mentions that certain reagents can rapidly corrode steel and asks for clarification on the movie reference.
  • A Thermite reaction is suggested as a method that can melt through steel, emphasizing the role of gravity and molten materials.
  • A specific chemical, royal water, is proposed as potentially effective, with conditions noted for its application and effectiveness.
  • Concerns are raised about the practical application of chemicals, such as the challenges of targeting specific parts of a lock.
  • A mix of nitric acid and hydrofluoric acid is suggested as a more effective solution for dissolving stainless steel, though it is noted that this would not be as quick as portrayed in movies.
  • Safety warnings regarding the inhalation of acid vapors are mentioned.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness and practicality of using chemicals to cut through hardened steel, with no consensus reached on the feasibility of achieving results similar to those shown in movies.

Contextual Notes

Limitations include assumptions about the conditions under which chemicals are applied, the specific types of steel being discussed, and the practical challenges of using these chemicals in real-world scenarios.

I have a bet that no chemical can cut through hardened steel like in the movies, will i loose?

There are some wicked reagents out there that can eat steel up pretty quick. Could you better define how you mean by 'in the movies'?

Not to mention stuff like a Thermite reaction that can quickly melt through steel just using gravity and a glob of molten hot iron and aluminum.

The secret agent has a phial of chemical , that will cut through the lock in seconds.
 
I don't know about exact rates, but a vial of freshly prepared http://en.wikipedia.org/wiki/Royal_water" could probably do it pretty quickly. Of course, this is ignoring the problems of applying the reagent to the lock, and is assuming something like a padlock where it could be poured directly onto the small locking arm to eat up/weaken that enough that it can be snapped off by hand.

Injecting it with a pipette into any other kind of key lock would certainly wreck the mechanism, but may or may not make it easier to open...

Royal water is good if you can heat it; at cold is better to have more HNO3 than HCl and add also HF; with this mix you can dissolve easily (but not as quickly as in movies) even stainless steel.
Don't breath the acid vapours.
