At the behest of @Lord_James, this shall be the thread for general discussion of conventional passive metallic armor. Whether it's steel, titanium, magnesium, exotic laminates of all three, this is the thread for it.
In answer to your earlier question, Lord_James, relatively small amounts of boron, in steels that have the appropriate levels of carbon, form intergranular barriers that dramatically slow the diffusion of carbon out of the austenite crystals during quenching. Long story short, this means that the depth of material that can be effectively hardened is much greater.
I was wondering, does anyone know of this mystery steel system called "triple hardness steel" ? I was trying to find information on it like layout and hardness (BHN or VHN) but i could not find anything concrete on it anywhere. Although it gets mentioned in the AFV community fairly regularly, I can not find it anywhere. If anyone knows, please share it. Thanks in advance !

I'm interested in Soviet armor production and deployment. Especially of T-55 tank and its variants. Sadly, most sources touch this subject very generally while I would want to get a more detailed view. How much tanks were produced in which country and at what year. Were Soviets producing armor for themselves or for export. Any source which would go into bit more detail about it is appreciated. I would appreciate if someone could help me find information required about those tanks as so far I can rely only on quite general information.
