Drywall nail production process

      The price of drywall nails on the market now varies greatly. Cheap drywall nails only cost more than 5,000 ton per ton, and expensive ones are nearly double the price. So what is the reason for such a big price difference? Is it a change in the material or a problem in the production process? The production of drywall nails is a professional technical work, so it is difficult for us to distinguish whether it is High-quality drywall nails, then today let's take a look at the production process of drywall nails to see if we can find out the price of drywall nails at that step.
  The production process of drywall nails generally includes: heat treatment, quenching, annealing, tempering and other steps! Let us learn more about drywall nails!
  Drywall nails A method of changing the properties of steel by heating to different temperatures and then using different cooling methods. The commonly used heat treatments are: quenching, annealing, and tempering. What are the effects of these three methods?
  Dry wall nail quenching: heating the steel to above 942 degrees Celsius, so that the steel crystals appear Austenite state, and then immersed in cold water or cooling oil to quench the heat treatment method to make the steel crystals appear in the martensitic state. This method can increase the strength and hardness of the steel. There is a very big difference in the strength and hardness of the steel with the same label after quenching and without quenching.
  Dry wall nail annealing: a heat treatment method in which the steel is also heated to an austenitic state and then naturally cooled in air. This method can reduce the strength and hardness of the steel, improve its flexibility, and facilitate processing. Generally, steel will go through this step before processing.
  Tempering: Whether it is quenched, annealed or press-formed, steel will generate internal stress, and the imbalance of internal stress will affect the steel structure and mechanical properties from the inside, so a tempering process is required. The material is kept warm continuously at a temperature of more than 700 degrees, and its internal stress is changed and then cooled naturally.
   The above is the detailed production process of drywall nails. I hope it can help you when identifying drywall nails.
