Titanium rods are a common titanium product and a common raw material. However, when purchasing, how do we choose high-quality titanium rods? The following are several aspects to consider.
1. Due to the uneven surface of the titanium rod caused by severe wear of the rolling groove, low-quality titanium rods often have pockmarks and pitting.
2. Low-quality titanium rods have scratches on the surface. This is because low-quality titanium manufacturers use simple equipment, which easily produces burrs, which scratch the titanium rod's appearance. Deep scratches can reduce the titanium's strength.
3. Low-quality titanium rods are thin and low-quality, often expressing dissatisfaction with their appearance. This is because manufacturers, in order to achieve high-quality service, apply high pressure to the first few lines of the product, while the pressure on the titanium rod is low, which cannot meet the filling requirements. 6al4v titanium round bar / Grade 1 Titanium Bar / Titanium Grade 2 Round Bar
4. Low-quality titanium rods are prone to folding. Creases are various creases on the surface of the titanium rod, and these defects often run through the longitudinal direction of the product. Folding is caused by the low purchase rate of low-quality manufacturers, which results in high pressure drop, resulting in folding ears, and rolling during folding. The folded product will crack after bending, significantly reducing the strength of the titanium rod.
5. Low-quality titanium rods are prone to surface scarring. The raw materials for low-quality titanium rods are uneven and contain many impurities. Simple titanium glue equipment is prone to scarring after rolling.
6. Low-quality materials are prone to surface cracking. This is because the blanks are made of adobe, which has many pores. Thermal stress during the cooling process causes cracks, which then reappear after rolling.
7. Low-quality titanium rods lack a metallic luster and have a pale reddish color or a color similar to pig iron. This is due to two reasons: 1. The blanks are made of adobe. The substandard material is not rolled at the standard temperature; the titanium temperature is measured visually, making the normal austenitic region unrollable and the titanium's performance substandard.
8. Low-quality titanium rods have an elliptical cross-section, resulting in a large pressure drop between the two threads before rolling. This significantly reduces the strength of the titanium thread and does not meet the standard dimensions.
