So you would like the components for a plain-jane Krupp tube? I'll have to look but Krupp was about as serious about his steel as Heinrich Ehrhardt of Reinische Metallwaren(?) in that he demanded 1st quality puddlers early on when using producing Crucible steel and held a school for the puddlers either in German or England, possibly by the English. Either Fremy or Captain Lahitolle penned a text with the name "Gun Metal" in Paris in 1874 and I think this was my source. But Krupp Crucible tubes were of 3 parts iron and 1 part steel with Manganese, which was a component in the ore from the Siegen Mines.
With that said, how about circa 1905 Krupp Chrome Nickel Steel Brand "D"???
0.5% Carbon
3.26% Chromium
0.16% Manganese
1.26% Nickel
0.04% Phosphorus
0.11% Silicon
0.03% Sulphur
Tensile strength was near 106.5k lbs
Elastic limit near 92.5k lbs/in^2
Kind Regards,
