Causes of open ring expansion and hydrogen embrittlement fracture

1. 304 Stainless Steel Washers Of Stamping Part With Two Holes is generally not a problem of the spring washer itself

2. The spring washer that expands the ring must be subjected to a radial external tension, which is derived from the tightening axial force generated by the tightening torque

3. The outer chamfer of the nut bearing surface produces a radial component of the axial clamping force, which causes the opening of the spring washer to expand. The smaller the chamfer diameter, the greater the possibility of ring expansion

4. Adding a flat washer between the nut and the spring washer helps to slow down or prevent the expansion of the ring, but the flat washer is too thin or too soft to prevent the expansion of the ring

5. 304 Stainless Steel Washers Of Stamping Part With Two Holes generally due to unreasonable heat treatment process, and the fracture caused by the failure to do the dehydrogenation treatment in time after electrogalvanizing.

A large number of experiments and long-term practical experience have confirmed the above analysis.

There are many sharp elastic warped teeth on the circumference, which are pressed against the supporting surface to prevent the loosening of the fasteners. Internal tooth elastic washers are used under screw heads with smaller head sizes; external tooth elastic washers are mostly used under bolt heads and nuts. Toothed elastic washers are smaller than ordinary spring washers, and the fasteners are evenly stressed and reliable in preventing loosening, but they are not suitable for frequent disassembly.
