Fastener users often reflect why stainless steel fasteners sometimes have locking problems, and similar phenomena do not occur when using carbon steel fasteners. Is stainless steel fasteners softer, carbon steel? The reason why fasteners are relatively hard? Yes! Stainless steel and carbon steel are essentially different. Fastener users often reflect why stainless steel "target=_blank> stainless steel fasteners sometimes have locking problems, and similar phenomena do not occur when using carbon steel fasteners, is stainless steel" target= _blank>Stainless steel fasteners are softer, carbon steel fasteners are relatively harder? Yes! Stainless steel "target=_blank> stainless steel and carbon steel are essentially different. Stainless steel "target=_blank> stainless steel It has good ductility, but its hardness has a certain gap with carbon steel. However, this statement can only be said to be half right.
Locking often occurs on stainless steel "target=_blank> fasteners made of stainless steel, aluminum alloy and titanium alloy. These metal alloys have rust resistance and will produce a layer on the metal surface when the surface is damaged. A thin oxide layer prevents further deeper rust.
When the stainless steel "target=_blank> stainless steel fastener is locked, the pressure and heat generated between the teeth will destroy and erase the chromium oxide layer between them, causing the metal tooth to directly block/shear and then adhere. Phenomenon. When the sticking phenomenon continues (usually no more than one full caliper), the stainless steel "target=_blank> stainless steel fasteners are completely locked and can no longer be removed or locked. Usually a series of blocking, shearing→adhesive→locking actions take place in just a few seconds. Therefore, understanding the characteristics of stainless steel “target=_blank> stainless steel products and following the correct procedures is to prevent stainless steel” Target=_blank>The first step in locking stainless steel fasteners.
Many users will encounter stainless steel "target=_blank> stainless steel screws and nuts lock up during the screwing process, the reason is nothing more than 304 (or 316) this material is more ductile and sticky, this One point we can clearly see from the turning process, the experienced teacher Bo will find that the 304/316 bar is in the process of machining, its chip discharge is extruded and wrinkled, and other materials such as brass or iron The chip removal during the turning process is crumb-like or silky.
If the power tool is used for quick screwing or when the stainless steel "target=_blank> stainless steel screw and the nut are subjected to a large torque, the thread contact starts to heat up, and a certain contact point is stuck to drive a large piece. The result is the internal thread and the outer thread. The threaded bonds are locked together, and the set of bolts is scrapped. Of course, the entire installed workpiece may also become a defective product.
Summarize the effective large-radius reduction or completely avoid the stainless steel "target=_blank> stainless steel screw lock occurs during the installation and use of the process. We control the thread protection in the semi-finished tooth decay and finished transport packaging (of course Even if the thread is damaged, such as the tooth peak damage does not affect the anti-locking scheme. Users do not use power tools or overload torque or stainless steel "target=_blank> stainless steel screws and nylon lock nut screwed in at high speed, not It will lock up and be used like carbon steel. Users can minimize or even avoid losses without changing the installation tools and installation methods during use.
Of course, the cost of this stainless steel "target=_blank> stainless steel screw anti-locking solution is controllable and low, with little or no additional cost.
