Why is 150mm stainless steel screws easy to break?

I received an inquiry from a UK customer last week for 150mm stainless steel screws. The customer feedback said that the 1150mm stainless steel screws he had bought before were easy to break, so now he has to change the supplier. I asked the customer what process his previous supplier used to produce. And to explain to customers that the long screws of Shenzhen Shi Shi Tong screw factory are processed by cold-forming molding of the mold clamping machine.

In fact, long screws are easy to break because the long screws are formed by welding, which is easy to break.

In general, 150mm stainless steel screws are rarely broken because the stainless steel screws themselves are harder. Of course, the following reasons can also cause the stainless steel screws to break: 1. The quality of the raw materials used in the stainless steel screws, the quality of the stainless steel screw wires is not good. There are a lot of impurities, impure, resulting in insufficient hardness of stainless steel screws. 2. The problem of producing stainless steel screws. For example, the stainless steel screws with eccentricity and the Q value are too deep and the R position is too small during the manufacturing process. 3. Customers Excessive force when using stainless steel screws. Generally, you can do a lower torque test to see what the minimum breaking force is, and then adjust the torque. But the above three reasons are the main reason for the fracture of 150mm stainless steel screws. When the stainless steel screw is found to be broken, it can be checked step by step. See what causes it.
