Simple Identification Of The Quality For Titanium Rods: Comprehensive Analysis

When purchasing titanium rods, it is essential to ensure that high-quality titanium rods are purchased. However, how to accurately distinguish the quality of titanium rods is a process that requires professional knowledge and careful observation. Below, we will analyze in detail how to distinguish the quality of titanium rods from many aspects and angles.

1. Observe The Surface Condition 

1) Hemp surface phenomenon: Hemp surface often appears on the surface of shoddy titanium rods. This is due to the severe wear of the rolling groove, which causes the surface of the titanium material to be irregular and uneven. Therefore, when buying, pay special attention to whether the surface is flat and smooth. 

2) Scratch marks: Shoddy titanium rods are prone to scratches during production and transportation, which are often caused by rudimentary equipment or improper operation.Deep scratches will reduce the strength of the titanium material and affect the use effect.

2. Check The Cross-Section And Tendons

1) The horizontal ribs are thin and low: The horizontal ribs of shoddy titanium rods are usually thin and low, and dissatisfaction often occurs. This is due to the manufacturer's pursuit of negative tolerances, the amount of pressure in the first few stages during the rolling process is too large. 

2) Folding problem: Folding is a kind of polyline defect formed on the surface of the titanium rod, which runs through the entire longitudinal direction of the product. Due to the pursuit of high efficiency and the large amount of pressure, the shoddy titanium rod is prone to ears and folds when it is rolled in the next step. Folded products are easy to crack after bending, which seriously affects the strength.

3. Pay Attention To 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 pig iron-like color. This is usually due to uneven raw materials, many impurities, or irregular rolling temperature.

4. Observe Surface Defects 

1) Scarring phenomenon: The surface of shoddy titanium rods is prone to scarring. This is due to the high impurities of raw materials or the rudimentary guide guard equipment, which causes impurities to adhere to the roll and produce scarring. Scarring can affect the appearance and performance of titanium rods. 

2) Crack problem: Cracks may also appear on the surface of shoddy titanium rods, which is mainly due to the fact that the raw material is adobe and there are many pores. During the cooling process, it is prone to cracks due to thermal stress, and cracks form after rolling.

5. Check The Size And Shape

Cross-sectional shape: The cross-section of a shoddy titanium rod may be oval instead of non-standard round or square. This is due to the fact that the manufacturer adopts a large amount of pressure in the first two channels of the finished roller in order to save materials. Titanium rods of this shape not only affect aesthetics but also reduce strength.

When purchasing titanium rods, carefully observe their surface condition, check the cross-section and ribs, pay attention to the color and gloss, and observe surface defects. Only by fully understanding and mastering these identification skills can we ensure the purchase of high-quality titanium rod products.
