    At high temperature near the melting point of metals like steel, hydrogen embrittlement becomes a relevant issue. Its basically hydrogen atoms that make it into the metal crystal lattice making the metal more brittle than it would normally be.

      It’s well-enough solved to produce a product that’s useful for things like making bicycles or cars. There are some specific situations (eg: the cables on a suspension bridge) where it’s probably an issue still.

        Guys used to complain about Chinesium metal. Now that stuff is used in a more purposeful way only for housings and such. Harder material for bearings and gears. The quality has improved quite a bit on tools.
