Still working on reported tensile strength of 1890 - 1900 steels. Found this old thread by Raimey with lots of information

BUT I'm having trouble keeping up with Krupp who developed several fluid steels after 1890, and which Belgium likely copied. Any help?

Krupp (Open Hearth): 70,000 - 80,000 psi
Krupp Fluss Stahl (Homogeneous) about 1890: ?
Krupp Nickel Steel patented in 1890: 92,500 psi
Krupp Special (1896 Spezial Gewehr Lauf Stahl): ?
1905 Krupp Chrome Nickel Steel D: 106,500 psi
