When purchasing titanium rods, it is essential to ensure their quality. TOPTITECH teaches you to distinguish between high-quality and substandard titanium rods, by considering the following aspects:
1. Surface Appearance:
Counterfeit and substandard titanium rods often have a pockmarked surface. This irregularity results from excessive wear on the rolling groove during manufacturing.
2. Susceptibility to Scratches:
Fake and substandard titanium rods are easily scratched due to the use of inferior equipment during production. These scratches can significantly reduce the strength of the titanium material.
3. Inadequate Horizontal Bars:
Low-quality titanium rods often exhibit thin and unsatisfactory horizontal bars. This occurs when manufacturers apply excessive reduction in the initial passes, resulting in insufficient filling of the iron and hole shapes.
4. Prone to Folding:
Folding is a common defect found in fake and substandard titanium rods. It manifests as fold lines running longitudinally across the entire product. Manufacturers seeking high efficiency employ excessive reduction, resulting in ear formation and subsequent folding. Bent folded rods are prone to cracking and significantly reduced strength.
5. Scarring on the Surface:
Fake and substandard titanium rods frequently display scarring on their surface. This can be attributed to uneven raw materials with numerous impurities and the usage of inadequate guide and guard equipment during the rolling process.
6. Cracks:
Substandard titanium rods often develop cracks due to the presence of pores in their adobe blanks. The cooling process induces thermal stress, leading to crack formation. These cracks persist even after rolling.
7. Lack of Metallic Luster:
Fake and substandard titanium rods lack the characteristic metallic luster and appear light red or similar to pig iron. This is primarily caused by the use of Adobe blanks and non-standardized rolling temperatures. Inadequate temperature control prevents proper rolling within the regular austenite area, resulting in titanium material with substandard properties.
8. Oval Cross Section:
Substandard titanium rods may exhibit an oval cross-section due to excessive reduction in the first two rolling passes, resulting from material-saving measures.
Identifying these characteristics can help assess the quality of titanium rods and ensure that only high-quality products are selected.
