The common defects and prevention measures of spring quenching
Common defect of spring quenching, let’s introduce some prevention measures:
Defect I: Decarburization( lower use life ); Measure:1. Using a salt bath furnace or atmosphere furnace heating;
2. Using rapid heating process.
Defect II: Lack of hardness after quenching, the number of non-martensite is too large, the core appear ferrite; Measure:
1. Choose good harden ability materials;
2. Improve cooling capacity of the quenching coolant;
3. The temperature of spring enter into the coolant should be controlled above Ar3
4. Appropriate improve quenching heating temperature.
Defect III. Overheating (Brittleness increases);Measure
1. Strictly control heating temperature of forming and quenching;
2. Strengthen the quenching in metallographic examination.
Defect IV. Cracking(Brittleness increases, lower use life severely); Measure:
1. Control quenching heating temperature.
2. When quenching and cooling to 250-300°, then take out and cooling in the air;
3.Tempering timely.
