A.P. Curtis, General Manager of the Ithaca Gun Co. requested composition analysis and tensile strength testing on a section “cut from a barrel made in Belgium” performed by E.J. Stormer, Racine, Wisconsin in 1919.

Carbon .32%
Manganese .78%
Phosphorus .018%
Sulphur .033%
No chromium nor nickel
Tensile strength was “about 70,000” psi

This is very similar to a sample of Parker Titanic Steel recently analyzed and published in Parker Pages by Dave Suponski
Carbon .32%
Manganese .70%
Phosphorus .033%
Sulfer .077%
BUT the Titanic steel had .078% Nickel and .031% Chromium

Trojan Steel
Carbon .35%
Manganese .84%
Phosphorus .03%
Sulphur .025%
Nickel .04%
Chromium .02%

Unfortunately, the date of manufacture of neither barrel is known, and the composition may certainly have changed in the years after WWI.
So- Titanic steel has a sulfer composition, but the way cheaper Trojan grade Parker with the Trojan steel barrels has a sulphur composition- Thank you, oh LaufMeister Drewbie-silly old me, I had the Parker barrels pegged at the AISI 1140 range- just shows to go ya that even an old pipeliner with API, AWS and ASTM certification under his Huntsman hood doesn't know all there is about metallurgy-many thanks for the most enlightening analysis- RWTF
