Why are stainless steel nuts easier to slip teeth than carbon steel nuts? When we use stainless steel hexagon nuts, we often encounter slippage, which makes stainless steel nuts unusable; and carbon steel nuts rarely have this situation. So what is causing this annoying problem?
Under normal circumstances: stainless steel nuts of the same diameter are not as strong and rigid as iron. Both carbon steel and stainless steel contain carbon elements, and the greater the proportion of carbon contained, the higher the hardness and strength of the metal. Carbon steel below 3% is carbon steel, and stainless steel below 1.5%. It is obvious that the hardness and strength of carbon steel is higher than that of stainless steel. When the screw is screwed into the hex nut, the nut will be subjected to torque. The range of torsion force depends on the strength of the nut itself. The greater the strength, the larger the range of torsion force.
Every aspect of the production of hexagon nuts is very important:
1. Starting from strictly selecting the original wire of the nut, whether it is stainless steel or carbon steel.
2. The size of the wire diameter determines the stability of the nut's quality, and the size of the hexagonal nut needs to be selected with the same specification and model of the nut wire.
3. The choice of nut machine and the corresponding tapping will affect the quality of the nut.
The strength of carbon steel is greater than that of stainless steel. It can be seen that the torsion range of carbon steel hexagon nuts is larger than that of stainless steel. When the torsion force of the hexagonal nut exceeds the acceptable range, the tooth will be slippery or even broken. At the same time, the stainless steel nut will lock up at this stage, also known as seizure. Since the torsion range of carbon steel nuts is larger than that of stainless steel, under the same torque, increasing the torque at the same pace will cause stainless steel nuts to exceed the range of torsion faster than carbon steel nuts, that is to say , Stainless steel nuts are more prone to slippage than carbon steel nuts.
