High Strength Thread Bar, also called Post-Tensioning Bar(PT Bar) is a super-important product in engineering application ,more and more customers need the material with full traceability, steel melting, rolling and heat treatment ,etc.
Yidao has complete traceability procedure on manufacturing and delivery, we will mark and take records once the material arrived, and mark separately on the Mill tag after heat treatment.
With reference of the batch number, it is easy for Yidao to find out which line and how the equipment status in manufacturing(including temperature, water volum···
When steel is curved, it is important to keep the stress-strain curve ratio for mild steel in mind. Below is a stress-strain graph that reviews the properties of steel in detail.
If tensile force is applied to a steel bar, it will have some elongation. If the force is small enough, the ratio of the stress and strain will remain proportional. This can be seen in the graph as a straight line between zero and point A – also called the limit of proportionality. If the force is greater, the material will experience elastic deformation, but the ratio of stress and strain will not be propor···
