Engineers all over the world have used Macalloy systems in the most diverse of applications. Among these are bridges, government buildings, stadia, airports, and hotels, to name just a few. The longevity and design again reflect the level of innovation and quality, which have become firm components of Macalloy products. Macalloy 460 is a hot rolled carbon steel, with excellent mechanical properties. The thread is rolled, rather than cut. This gives rise to the use of smaller diameter bars for a given metric thread, resulting in material cost saving. The carbon Macalloy 460 is also a weldable steel with a maximum carbon equivalent of 0.55%. Arc welding may be carried out using standard techniques and low hydrogen rods. The Macalloy 460 bar has the following mechanical properties: Minimum Yield Stress 460 N/mm2 Minimum Breaking Stress 610 N/mm2 Minimum Elongation 19% Minimum charpy Impact Value 27J @-20°C Nominal Young’s Modulus 205 kN/mm2 The standard diameter range for this system is from M10 to M100. In addition, other diameters can be supplied but are subject to longer lead times. Tendons up to and including M16 diameters can be supplied in lengths of 6m. For larger diameter, lengths of up to 11.95m are available. Greater lengths are possible using couplers and turnbuckles. These fittings are designed to take the full load of the bar. Adjustments within each fork or spade are: M10 to M56: +/- 1/2 thread diameter M64 to M100: +/-25mm Turnbuckles give additional adjustments of:
