The Common defects and preventions early in the year steel wire's quenching

• During the treatment of spring steel wire, the procedure can't always be favoring. And there are different problems and defects. The defects throughout the spring steel wire's quenching will change the performance of the spring. This is some prevention we usually included in the quenching.
• The decarburization of spring steel wire can simply reduce the use life of spring. We usually use two ways to avoid this condition. One is heated the spring steel wire with salt-bath furnace, permanently is to apply the rapid heating process.
• The hardness of spring is just not enough will lead the transformation reducing the service life. We usually simply select the spring steel wire that has good hardenability or improve the cooling ability of quenching cooling agent. Sometimes, add to the quenching heating temperature. Besides, the temperature when spring enter into the cooling agent should control above Ar3.
• The temperature of spring steel wire is way too high will add the brittleness of spring. We control the quenching heating temperature, besides, we also strengthen the metallographic examination while in the quenching.
• The spring steel wire's brittleness will increased due to the crazing during the quenching, the crazing will even reduce the service life of spring. We control the quenching heating temperature and tempering imediately.
• The spring created by the spring steel wire which quenching process is treated as below is greater than others, you will see the advantages once you've a try.
