As a qualified and professional titanium rod manufacturer, Shaanxi Etermal Co., Ltd. has been committed to providing high-quality products and services to customers at home and abroad. Today, we will take you to learn how to identify inferior titanium rod products.
1. The appearance of counterfeit and inferior products often has pockmarks. The pockmarked surface is a shortcoming of the irregular and uneven surface of the titanium material due to the serious wear of the rolling groove. This is because manufacturers of counterfeit and inferior titanium rods want to obtain more profits, so they often overrun the groove rolling.
2. Fake and inferior products are easy to scratch. This is because the equipment of the fake and inferior titanium rod manufacturers is not enough to produce high-quality products, and the equipment is prone to burrs and scratches on the appearance of titanium materials. Scratches reduce the strength of titanium.
3. The horizontal ribs of fake and inferior products are thin and low, and often appear to be full. The reason is that in order to achieve a large negative tolerance, the reduction of the first few passes of the product is too large, the iron mold is too small, and the pass is not full.
4. Fake and inferior products are prone to folding. Folding is the individual fold lines formed on the surface of titanium rods, and this defect often penetrates the longitudinal direction of the entire product. The reason for the folding is that the counterfeit and inferior manufacturers pursue high efficiency, and the reduction is too large, resulting in ears, and the folding occurs in the next rolling process. The folded product will crack after bending, and the strength of titanium is large and low.
5. Fake and inferior products are prone to scarring on the surface. There are two reasons:
(1) Titanium sponge, the raw material of fake and inferior titanium rods, is not of high quality, with uneven texture and many impurities.
(2) Manufacturers of fake and inferior materials have poor equipment and are easy to stick to titanium. These impurities are prone to scarring after rolling.
6. The appearance of fake and inferior products is prone to cracks. This is because its billet may be adobe, and adobe often has the problem of many pores, and the adobe is prone to cracks due to the effect of thermal stress during the cooling process. There are cracks after making.
7. Fake and inferior products have no metallic luster and are light red or similar in color to pig iron. The reason is that its blank is in adobe. Moreover, the rolling temperature of fake and inferior materials is not standardized, and their titanium temperature is measured visually, so they cannot be rolled according to the regular austenite region, and the function of titanium materials cannot be qualified.
8. The cross-section of fake and inferior products is oval. The reason is that in order to save materials, the reduction amount of the first two passes of the product roll is too large. This kind of threaded titanium greatly reduces the strength of the product, and it does not meet the specifications of the threaded titanium shape.
