"The steel that is used in the cylinder of the K-22 is identical in formula with that used in the larger calibers, but it is not heat-treated after machining as the great thickness of the cylinder walls do not demand any further strengthening. As a matter of fact, even in our larger calibers the steel as it comes from the mill shows a tensile strength in the neighborhood of 80,000 lbs., which does not make the additional strength gained by treating a necessity, but we do very much prefer the greatly increased factor of safety that is obtained with the 130,000 lbs. elastic limit that the treating gives."

Are there any questions?
