    DIN934 Weld Nut 10.9 Steel Blackened By Heat Treatment M8 - M24

    DIN934 10.9 steel Blackened by heat treatment M8-M24 weld nut for engine parts.


    Description

    Welding nut is a kind of nut suitable for welding outside the nut. It is generally made of weldable material and is thicker and suitable for welding. Welding is equivalent to turning two separate parts into a whole, melting the metal at high temperature and mixing it. After cooling down together, alloys will be added in the middle, and the interior is the effect of molecular force, and the strength is generally greater than that of the parent body.


    Features of heat treatment process operation method:
    1. Annealing operation method: After heating the steel to Ac3+30~50 degrees or Ac1+30~50 degrees or the temperature below Ac1 (relevant information can be consulted), it is generally cooled slowly with the furnace temperature.


    2. Normalizing operation method: heat the steel to 30~50 degrees above Ac3 or Accm, and cool it at a cooling rate slightly greater than that of annealing after heat preservation.


    3. Quenching operation method: heat the steel to above the phase transition temperature Ac3 or Ac1, keep it for a period of time, and then quickly cool it in water, nitrate, oil, or air. Purpose: Quenching is generally to obtain a high hardness martensite structure, and sometimes when quenching some high-alloy steels (such as stainless steel and wear-resistant steel), it is to obtain a single uniform austenite structure to improve wear resistance. and corrosion resistance.


    4. Tempering operation method: reheat the quenched steel to a certain temperature below Ac1, and after heat preservation, cool it in air or oil, hot water or water.
