anyone know what good pitons are made of?

does anyone know exactly what type of steel knifeblades, rurps, and beaks are made of. tempered,....hardened.....whats the deal? what kind of steel were the original stoveleg pitons made of? just curious on that one. was making some for fun..... despite the hammer deal,on some climbs, they just fit way more solid than any other new,modern gear you could place clean. the sound of a good blade placement excites me. is the sound an indication of its structural integrity? anyone out there make any and test them? |

Here is a place to start |

I don't make them, but I happen to deal with a lot of steel on a daily basis so I could take a guess. Could be wrong, but I can try. |

Generally speaking there are two types of pitons; soft and hard. A few companies still make both kinds. Soft pitons conform to the area you are hammering them in and hard ones stay rigid. |

those titanium pins have worked really well for me |

We had a very thin sheet of steel we wanted coated with an aluminum/silicon alloy for adhesion promotion, but it was too thin to purchase the hot-dipped aluminized steel sold by AK Steel, so we had to get it electrolytically coated (too thin to sand blast so we couldn't thermal spray either) by the only company in the US apparently that would do it. Cost about 400 bucks. |

What were you making? Some kind of electronics board? |

It was part of research to test the adhesion with a linear LDPE in a solution that I can't really remember what it was. It had to be thin because of the limitations of the press that was used to heat it. It wasn't my money though...but still. |

I believe pitons were always hot forged and hammered and hardened by quenching - at least I think that's the way Chouinard made them years ago. I do not believe they are carbon at all. I thought chromemoly myself...not sure tho now. |
