Various grades of reinforcing rod such as ic used in building construction we;ce
available but quality and strength characteristics varied widely from sample to sample.
One of the better rods available in this clase was a 6 ma wire rod produced locally to
Japanese Standard Specification SS41. This steel gave, on test, a tensile strength of 8.9 kg/mm2 (14,000 psi), An imported hard drawn stool wire of 6 mm (1/4") diamotor
was also:available but only in short lengths and this, on test, gave a lower tensile
strength of 8,9 kg/mm2 (12,600 psi). Although hard drawn or high tensile steel rode
are more suitable from the point of view of less distortion and be-t fairing, both
the lower tensile strength and the short lengths, necessitating considerably moro
lapping of rode in the construction, excluded the imported hard drawn rod.
The choice of the 3S41 6 mm (1/4"). rod was largely dictated by local supplies, and
should high tensile, prestressing steel in the required diameters become readily
available then this would be a better choice in the future.
