Mn: 0.35-0.60
Cr: 0.70-1.00
Ni: 3.00-3.75
MECHANICAL PROPERTIES
Yield: 540Mpa
Tensile strength: 700/770Mpa
Elongation: 25%
Hardness: 255HB
HEAT TREATMENT
655M13 has good heat treatment ability and can be quenched and tempered to increase hardness and strength.
Quenching: 655M13 can be quenched to achieve an increase in hardness. For example, oil quenching or water quenching can be performed to achieve different hardness levels.
Tempering: Tempering after quenching can reduce quenching stress and improve toughness and impact properties. Tempering temperature and duration will affect the final hardness and toughness.
Annealing: In some cases, 655M13 may require annealing to soften the material and improve its machinability.
Normalizing: Normalizing can improve the microstructure of the material and improve its uniformity in preparation for subsequent heat treatment or processing.
Hardness range: After heat treatment, the hardness range of 655M13 can range from 180-220 HB, depending on the specific parameters of the heat treatment.
