The Remington 1889 hammer gun No. 1 had decarbonized steel and was "Guaranteed For Nitro Powders"
Bessemer/Decarbonized steel tensile strength is about 63,000 psi, similar to AISI 1018 Low Carbon (Mild) Steel.
For comparison, the average tensile strength in my study for crolle Damascus was 54,500 psi.
"Remington Steel" used on the Model 1900 was likely similar to Winchester and Marlin "(Cold) Rolled (Bessemer) Steel", with a tensile strength of 66,000 - 70,000 psi.
"Remington Ordnance Steel" was introduced in 1897 for the 1894 Hammerless Double and had a reported tensile strength of 110,000 psi.
