Material shall be vacuum carbon-deoxidized, in
which case the silicon content at the time of vacuum deoxidizing shall be 0.12 % maximum, and the content of deoxidizers such as aluminum, zirconium, and titanium should be kept
low enough to allow deoxidation by carbon. The test report
shall indicate that the steel was vacuum carbon-deoxidized.
The minimum heat analysis and product analysis requirements
for silicon do not apply to vacuum carbon-deoxidized steel.
