As a common titanium product and raw material, titanium rods are widely used in many fields. However, facing the dazzling array of titanium rod products on the market, how to choose high-quality titanium rods has become the focus of many users. The following will introduce you to how to identify and choose high-quality titanium rods based on several key characteristics.
How to choose high-quality titanium rods?
- Appearance inspection
1. Surface uniformity: The surface of high-quality titanium rods should be smooth and uniform, without unevenness such as pockmarks and pits. These unevennesses are often caused by severe wear of the rolling groove, which will affect the appearance and performance of the titanium rod.
2. Scratches: Check whether there are scratches on the surface of the titanium rod. Due to the simple production equipment, inferior titanium rods are prone to burrs and scratches on the appearance of titanium materials. Deep scratches will reduce the strength of titanium and affect the use effect.
3. Shape and size: choose high-quality titanium rods that 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 pressure of the production line in order to achieve a large negative service.
- Folding and scarring
1. Folding phenomenon: Creases are various creases formed on the surface of titanium rods, and this defect often runs through the longitudinal direction of the product. Poor-quality titanium rods are easy to fold because the manufacturer's downward pressure is large, resulting in problems such as folded ears and cracks, which seriously affect the strength of titanium.
2. Scar situation: The surface of high-quality titanium rods should be free of scars. Scars are usually caused by uneven raw materials, many impurities, and simple production equipment. Scars will affect the appearance and performance of titanium rods.
- Cracks and color
1. Grain inspection: Check whether there are cracks on the surface of the titanium rod. The blank of the inferior titanium rod may contain many pores, and cracks will appear due to the influence of thermal stress during the cooling process. These cracks will become more obvious after rolling, seriously affecting the strength and performance of the titanium rod.
2. Color judgment: choose high-quality titanium rods that should have a metallic luster. Poor-quality titanium rods may appear reddish or similar to pig iron, which is caused by poor billet quality or non-standard rolling temperature.
- Cross-section and strength
1. Cross-section shape: The cross-section of high-quality titanium rods should be round or standard. The cross-section of low-quality titanium rods may be oval or irregular, which is caused by the large pressure drop of the two lines before the roller. The strength of titanium threads in this shape is greatly reduced and does not meet the specifications.
2. Strength test: The strength of titanium rods is tested by professional strength testing equipment to ensure that they meet the requirements of use. The strength of low-quality titanium rods is often low and cannot meet the high-standard use requirements.
In summary, choose high-quality titanium rods requires comprehensive consideration of appearance, folds and scars, cracks and color, cross-section, and strength. Only by choosing high-quality titanium rods produced by regular manufacturers can we ensure that the performance and quality of the product meet the requirements of use. I hope the above content can provide a useful reference for your purchase.
