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 proportional. This is between points A and B, known as the elastic limit. Beyond the elastic limit, the mild steel will experience plastic deformation. This starts the yield point – or the rolling point – which is point B, or the upper yield point. As seen in the graph, from this point on the correlation between the stress and strain is no longer on a straight trajectory. It curves from point ...

There are so many   types of rebar   on the market today that it's easy to see how the quality can vary, so how can we identify good and bad rebar in our purchases? Let's find out today. When purchasing rebar, we need to pay attention to three points.   First of all, the surface quality of regular steel is free of cracks, scars and folds. The surface of the rebar should be free of cracks, scars and folds.  The surface of the rebar  should have bumps, but they should not exceed the height of the horizontal ribs. The surface quality of shoddy rebar is poor because it is rolled with adobe, often with burrs, burrs, cracks, scars, some twists, untidy ends and even cracks. At the same time some small rolling mills due to the heating temperature, rolling speed is not enough, the surface color is red, uneven color.   Dia 20mm-500 Thread Bar   Second, identify from the size. Vernier calipers can be used to simply measure whether the actual size is consiste...
