A feasible method to identify fake and inferior titanium rod products
When we are buying titanium rods, we all want to buy high-quality titanium rods, but how do we distinguish the quality of titanium rods? Xigong Titanium Alloy teaches us how to make titanium rods from many aspects and angles.
1. Counterfeit and inferior titanium rods often have the appearance of pitting.
The pitted surface is the shortcoming of the irregular surface of the titanium material due to the severe wear of the rolling groove. Because manufacturers of counterfeit and inferior titanium rods are looking for profit, the groove rolling is often the most overrun.
2. The fake and inferior titanium rods are simply scratched. The reason is that the equipment of the fake and inferior titanium rod manufacturers is simple and prone to burrs and scratches on the surface of the titanium material. Deep scratches reduce the strength of titanium.
3. The cross ribs of fake and inferior titanium rods are thin and low, often showing the appearance of dissatisfaction. The reason is that in order to reach the big negative service, the reduction of the first few passes of the product is too large, the iron type is too small, and the hole type is not full.
4. Fake titanium rods are easy to fold.
folds are various fold lines formed by the appearance of the titanium rod. This shortcoming often runs through the longitudinal direction of the entire product. The reason for the folding is that the fake and inferior manufacturers seek high efficiency, the reduction is too large, the ears occur, and the folding occurs during the next rolling, the folded product will crack after bending, and the strength of the titanium material will be greatly reduced.
5. The appearance of fake titanium rods is prone to scarring.
There are two reasons for : (1) The raw materials of fake and inferior titanium rods are uneven and there are many impurities. (2) The guide and guard equipment of the fake and inferior material manufacturers is simple and simple to stick to titanium. These impurities are prone to scars after biting the roll.
6. The appearance of fake and inferior materials is prone to cracks. The reason is that the billet is adobe, which has many pores. The adobe cracks due to the effect of thermal stress during the cooling process, and cracks occur after rolling.
7. The fake and inferior titanium rods have no metallic luster, and are light red or similar to the color of pig iron. The reason is two points. Its blank is adobe. The rolling temperature of the fake and inferior materials is not standardized, and their titanium temperature is visually inspected, so that the rolling cannot be carried out in the regular austenite area, and the function of the titanium material is naturally not qualified.
8. The cross section of the fake titanium rod is elliptical. The reason is that in order to save data, the manufacturer has a large reduction in the first two passes of the product roll. The strength of this threaded titanium is greatly reduced, and it does not meet the size of the threaded titanium. specification.
