In fact, there is no problem with the quality of the 304 stainless steel tube plate itself, but due to the characteristics of the product itself, the elongation of the 304 stainless steel plate is small but the hardening index is high.
1. The cause of the formation of cracks
The austenitic 304 stainless steel pipe has a higher cold work hardening index, and the austenite is a sub-stable structure, so when the material is deformed, it will cause the martensite phase, and the martensite phase is brittle, so it is very easy to produce cracks, in the processing process, the greater the stretch and deformation of the material, the higher the martensite content of the hair, so the higher the probability of cracks in the processing process.
2. Causes of surface scratches
The reason for the surface scratches is mainly because the 304 stainless steel pipe moves relative to the mold during processing, and under a certain pressure, it is very easy to leave abrasions and scratches on the surface of the material.
