Identification of Aircraft Tubing by Rockwell Test
Abstract
Seamless steel tubing is to-day the principal material of construction for aircraft. The commercial grade of tubing containing about 0.10 to 0.20% carbon at first used is being superseded by two grades which are approved by the army and navy, and which are also becoming standard for commercial airplanes.
