1. Kgf/mm2 x 9.81 = N/mm2 = MPa
2. psi x 0.0007 = Kgf/mm2
3. 1.574 x Kgf/mm2 = Tsi
4. Ksi x 1000 = psi
5. Kgf/mm2 = Ksi
Raw material testing is one of the important factors which determines the quality of the finished product.
Since a slight change in the chemical composition and mechanical properties in the base rod can have a
major impact on the properties of the finished wire. KEI has state-of-the-art equipment for testing these
features accurately.
