1.8509 (41CrAlMo7-10) corresponds to the domestic material 38CrMoAl nitrided steel. 11.8509 has good strength and creep resistance at high temperatures and can maintain structural stability in high temperature environments. 1.8509 has good antioxidant properties and can resist oxidation and corrosion at high temperatures. 1.8509 has good wear resistance and is suitable for applications where resistance to wear and friction is required. 1.8509 has high toughness and can withstand shock and vibration loads.
1.8509 Purpose:
High-temperature applications: 1.8509 is often used in the manufacturing of parts in high-temperature working environments, such as automotive engine parts, gas turbine parts, etc.
Furnace equipment: Due to its good high-temperature strength and oxidation resistance, 1.8509 is suitable for manufacturing furnace equipment, such as heating elements, feeders, and furnace walls.
Bearing parts: 1.8509 is often used to manufacture bearing parts that withstand high temperatures and high loads, such as journals, rollers and cages.
Stamping dies: 1.8509 with wear resistance and toughness is suitable for manufacturing stamping dies, such as punches, die seats and guide pillars.
Other applications: 1.8509 can also be used to manufacture transmission parts, wire ropes, knives and other parts that require high strength and wear resistance.
1.8509 heat treatment method:
1. Preheating: Heating the workpiece to the appropriate temperature to reduce hot and cold stress and improve the heat treatment effect. The preheating temperature is generally between 800-850 degrees Celsius.
2. Quenching: Rapidly cool the preheated workpiece at an appropriate temperature to transform the structure and increase the hardness. The quenching temperature is generally between 870-910 degrees Celsius, and water, oil or other quenching media can be used.
3. Tempering: Heat treatment of quenched workpieces to reduce brittleness and improve toughness and strength. The tempering temperature range varies according to specific requirements, generally between 500-650 degrees Celsius. High-temperature tempering improves toughness, while low-temperature tempering improves hardness and strength.
4. Cooling: After tempering, properly cool the workpiece so that its temperature evenly drops to room temperature.
