Detailed Explanation of the Heat Treatment Process for High-Manganese Steel Hammers-Innally

Product Details

Preheating Stage
First, heat the hammer to 300-400°C for preheating to reduce thermal stress and deformation.
Maintain this temperature for approximately 1-2 hours to ensure uniform temperature throughout the hammer.
Heating Stage
The preheated hammer is then heated to 1050-1100°C, the austenitizing temperature range for high-manganese steel.
Maintain this temperature for a sufficient period of time to ensure complete austenite transformation throughout the hammer.
Quenching Stage
The heated hammer is quickly immersed in water or oil for quenching, achieving a hard yet brittle martensite structure.
During quenching, ensure the hammer is completely submerged to avoid stress concentration and deformation. 4. Tempering Stage
After quenching, the hammer head is immediately heated to 200-250°C for the first tempering stage.
Maintain this temperature for approximately 2-3 hours, then allow to cool naturally to room temperature.
Perform the second tempering stage at 500-550°C for approximately 4-6 hours, followed by slow cooling.
Cooling and Inspection
After tempering, allow the hammer head to cool naturally to room temperature.
Perform hardness testing and metallographic analysis on the hammer head to ensure that its performance meets the requirements.
Post-Processing
If necessary, surface treatments such as shot peening and plating can be performed to further enhance wear and corrosion resistance.
Finally, the hammer head is inspected for size and shape to ensure it meets the requirements.
Through the above heat treatment process, the high-manganese steel hammer head will achieve excellent overall performance, ensuring reliability and durability in practical applications.
