Usually used as a decorative tube plate is austenitic stainless majority of 304, in general, is a non-magnetic or weakly magnetic, but the chemical composition fluctuations caused by smelting or processing may occur in different magnetic state, but can not be considered counterfeit or substandard, which is what causes it? Austenitic mentioned above are non-magnetic or weakly magnetic stainless steel combination Heze screws, and martensite or ferrite is magnetic, due to smelting segregation or improper heat treatment of stainless steel screws in combination, can cause 304 austenitic stainless steel martensite or ferrite. Thus, the 304 will carry the weak magnetism. Stainless steel screws fracture reason is as follows: 1. Stainless steel screws quality raw materials used, poor quality wire stainless steel screws. There are many combinations of impurities Weihai stainless steel screws, impure, resulting in insufficient hardness of stainless steel screws. 2. The production of stainless steel screws process issues. For example, migraine eccentric combination of stainless steel screws stainless steel screws Yantai, there are production manufacturing jobs nowadays punch-Q, and R bits designed too small. 3. Customers in the use of stainless steel screws, excessive force. Generally you do the next torque minimum breaking strength test to see how much, and then you can adjust the torque.
