Titanium rod, as a common titanium product and raw material, has a wide range of applications in multiple fields. However, facing the dazzling array of titanium rod products in the market, how to choose high-quality titanium rods has become a focus of attention for many users. Starting from several key characteristics, we will introduce how to identify and select high-quality titanium rods.
1, Appearance inspection
1.Flatness The surface of high-quality titanium rods should be flat and consistent without any floor-like phenomenon such as pits or pockmarks. Such unevenness is known to be induced by severe wear in a roll groove, and it also deteriorates the appearance and performance of the titanium rod.
2. Scratch condition: Check whether there are scratches on the surface of the titanium rod. Poor quality titanium rods are prone to burrs and scratches on the appearance of titanium materials due to their simple production equipment. Deep scratches can reduce the strength of titanium and affect its performance.
3. Shape and Size: High quality titanium rods should have standard shapes and sizes. Poor quality titanium bars may be thin and low, with insufficient filling, which is caused by the manufacturer adjusting the production line pressure to achieve high load service.
2, Folding and Scaring
1. Folding phenomenon: Crews are various creases formed on the surface of titanium rods, which often run through the longitudinal direction of the product. Poor quality titanium rods are prone to folding due to the manufacturer's high pressure drop, which can cause problems such as folding ears and cracks, seriously affecting the strength of titanium.
2. Scar condition: The surface of high-quality titanium rods should be free of scars. Scars are usually caused by uneven raw materials, high impurities, and rudimentary production equipment. Scars can affect the appearance and performance of titanium rods.
3, Cracks and color
1. Texture inspection: Check for cracks on the surface of the titanium rod.Poor quality titanium rod blanks can have high porosity, which leads to cracking when it's subjected to thermal stress during cooling. They will be even more significant after rolling, which are critical to the strength and the performance of the titanium rod.
2. Color judgment: High quality titanium rods should have a metallic luster. Poor quality titanium rods may appear light red or have a color similar to pig iron, which is caused by poor quality of the billet or non-standard rolling temperature.
4, Cross section and strength
1. Cross section shape: The cross-section of high-quality titanium rods should be circular or standard in shape. The cross-section of inferior titanium rods may have an elliptical or irregular shape, which is caused by the large pressure drop between the two lines in front of the roller. This shape of titanium thread greatly reduces its strength and does not meet the specifications.
2. Strength testing: The titanium rod is subjected to strength testing using professional strength testing equipment to ensure that it meets the requirements for use.Poor quality titanium rod blanks can have high porosity, which leads to cracking when it's subjected to thermal stress during cooling. They will be even more significant after rolling, which are critical to the strength and the performance of the titanium rod.
Low quality titanium rods generally have weak strength and they couldn't be applied to high standard of usages. To sum up, the selection of quality titanium rods shall take multi-facet into consideration from the appearance, the folding and scarring, the cracks and the color, as well as the cross-section and the strength. We can only guarantee product performance, quality and superior service if we select quality titanium rods from the legitimate manufacturers.
