Simple To Identify The Quality Of Titanium Rods

When making titanium rod acquisitions, it is vital to ensure that you are purchasing quality titanium rods. However, how to accurately identify the quality of titanium rods is a process that requires specialized knowledge and careful observation. Below, we will analyze in detail how to identify the quality of titanium rods from various aspects and perspectives.
First, observe the surface condition
Pockmarked phenomenon: shoddy titanium bar surface often appear pockmarked, this is due to the rolling groove wear and tear caused by the irregularity of the surface of the titanium uneven. Therefore, when shopping, pay special attention to whether the surface is flat and smooth.
Scratch marks: shoddy titanium rods are prone to scratching in the production and transportation process, which is often caused by poor equipment or improper operation. Deep scratches will reduce the strength of titanium, affecting the use of the effect.
Second, check the cross-section and ribbing
Cross rib thin and low: shoddy titanium bar cross rib is usually thin and low, and often filled with the phenomenon of dissatisfaction. This is due to the manufacturers in pursuit of negative tolerances, in the rolling process, the first few passes of the underpressure is large.
Folding problem: Folding is a kind of folding line defect formed on the surface of titanium rods, which runs through the entire longitudinal direction of the product. Shoddy titanium rods due to the pursuit of high efficiency and the amount of underpressing is large, easy to produce ears and the next rolling in the formation of folding. Folded products are prone to cracking after bending, seriously affecting the strength.
Third, pay attention to the color and luster
Color and luster: high-quality titanium rods should have a metallic luster, while shoddy titanium rods may show a light red or similar to the color of pig iron. This is usually due to its uneven raw materials, impurities or rolling temperature is not standardized.
Fourth, observe the surface defects
Scarring phenomenon: shoddy titanium rods are prone to scarring on the surface, which is due to raw material impurities or guide the poor equipment resulting in impurities adhering to the roll and produce scarring. Scarring will affect the appearance and performance of titanium rods.
Cracks: shoddy titanium rods may also appear on the surface of cracks, which is mainly due to its raw material for the adobe and porous. Cracks are easily produced by thermal stresses during the cooling process and form cracks after rolling.
Five, check the size and shape
Cross-section shape: shoddy titanium rods may be oval in cross-section rather than the standard round or square. This is due to the manufacturers to save material in the finished roll before the second channel using a large amount of underpressure caused. This shape of titanium rods not only affects the aesthetics but also reduces the strength.
In the purchase of titanium rods to carefully observe its surface condition, check the cross-section and ribbing, pay attention to the color and luster as well as observe surface defects and other aspects. Only a comprehensive understanding and mastery of these identification skills can ensure the purchase of high-quality titanium rod products.
