Still hoping to accumulate more pre-WWI fluid steel samples for tensile strength testing and composition analysis.

Basic Bessemer steel
Carbon 0.07 - 0.09%
Manganese 0.40 – 0.48%
Phosphorus 0.05 – 0.08%
Sulfur 0.05 - .07%
Remington “Decarbonized Steel” and
Parker “Plain Steel” were Bessemer process steel, as was
Winchester Standard Ordnance “Rolled Steel” and
Marlin “Special Rolled Steel”. A 1925 Union Hardware & Metal Co., Los Angeles listing for the
Crescent Empire No. 60 states “Decarbonized Steel” barrels. Crescent barrels were labeled "Armory Steel".
Walt Snyder graciously shared a 1919
Ithaca Gun Co. letter from A.P. Curtis, General Manager requested tensile strength testing on a section “cut from a barrel made in Belgium” to be performed by E.J. Stormer of Racine, Wisconsin. The letter did not indicate if the barrels were “Smokeless Powder Steel” used on the Field grade, also commonly found with the ‘LLH’ mark of
Laurent Lochet-Habran, “Fluid Steel” or “Nitro Steel” used on the No. 1 and No. 1 1/2, Cockerill Steel used on the No. 1 Special, or “Best Fluid Steel” and Krupp on higher grades.
Tensile strength was reported to be “about 70,000” psi.
Carbon .32%
Manganese .78%
Phosphorus .018%
