    Hi, I'm involved in a game development, so I was wondering if you could help me determine the most realistic ordering of metal strength for vehicular protection(armor).

    Would this be the correct order of armor protection from weakest to toughest:

    1. steel
    2. carbon steel
    3. carbyne


    or would you suggest other ordering, or other materials, for a 3-tier armor protection?

    1) Carbyne isn't a metal.
    2) Nobody really uses (plain) steel or (plain) carbon steel for armour on vehicles any more1 (other than "light" vehicles).
    3) Carbyne may well be the "world's strongest material" but A) it's going to be horrendously costly to produce and B) currently the largest piece produced is only 6,400 atoms long. Hardly industrial quantities.
    4) Again with regard to carbyne's "strength" there's more involved to armour than just tensile strength....

    Why would you put the "toughest" armour on the inside?

    1 Despite armour values being given as RHA equivalents.

    But carbon steel is significantly tougher than regular steel? And has been used as a go to armor for the last two world wars?

    As for no longer being used in armor, are you referring to alloys: combining steel with titanium?

    What tough, but economical, carbon composite would you put instead of carbyne?

    It depends on what you mean by "tougher": it's less resilient for one thing.

    Armour tended to be face-hardened - i.e. one face of the sheet/ plate was carbon-enriched to make it "tougher" but the main body of the plate wasn't exactly "carbon steel"1.

    As for no longer being used in armor, are you referring to alloys: combining steel with titanium?
    Or ceramics, silicates, plastics, depleted uranium, punched (perforated) sheet steel....

    What tough, but economical, carbon composite would you put instead of carbyne?
    I wouldn't. Generally it's too flexible. Embedded carbon armour (in a metal/ carbon composite perhaps: but then you run into stiffness problems.

    1 Steel - by definition has to contain carbon2 anyway: otherwise it's "just" iron.
    2 Varying - depending on grade - from 0.05% to 4% (over 2.5% it's usually made by powder metallurgy - not exactly vehicle armour production quantities).

    By tougher I mean impact resilience.

    So, you would basically scrap my system entirely.

    Could you propose a 3-tier armor ordering/rating, given the definition I had offered?

    P.S.
    By 3-tier I mean 3 different armors, from least to highest impact resilience.

    vehicular protection(armor).

    Could you be more specific? We talking planes, cars, tanks?

    I guess start with these links for some inspiration and ideas:

    Given the utter and complete lack of selection criteria for those listing I wouldn't pay them too much credence.

    iron+carbon=steel

    1. steel
    2. titanium
    3. composites
