Fe 500
Mechanical Properties
- TI MACHO TMT bar combines High yield strength, High tensile strength and High elongation properties to deliver an unbeatable value proposition in structural steel.
- This value proposition has been developed through intensive R&D effort, which led in turn to a unique and computationally validated quenching process, relatively unaffected by process variations.
- TI MACHO TMT bars which undergo this intensive treatment develop a repeatable, reliable and optimized micro structure in cross section, leading to excellent mechanical properties.
Chemical Properties
- TI MACHO TMT Bars Carbon percentage is controlled within closed tolerances to insure High Ductility and Workability of steel.
- The overall Carbon equivalent CE is also tightly controlled to deliver an optimal combination of Hardness, Strength, Elongation and Weldability.
- Not more than 0.53 when micro alloying elements are used.
- Not more than 0.42 when micro alloying elements are not used.
