I'm sure it contained Chromium, I'm just not positive of the correct percentage. The 1st stainless/Antikorosnl oceli (Rostfreie Stähle) was exhibited at a Vienna Hunting Expo in 1910.

Cr, Ni, Mo, Cu, Si
In 1914 Ludwig Wundhammer notes he has had Poldi Antikorro tubes in stock for over a year and has rifled tubes for the New Springfield in 22 Highpower as well as Mausers. At this time Mr. Stewart Edward White is supposed to drop off his African Springfield to be fitted with a Poldi Anticorro tube.
