13CrMo4-4 Steel Grade: The Ideal choice for High-Temperature Applications

The 13CrMo4-4 steel grade is an ideal choice for high-temperature applications due to its excellent mechanical properties and chemical composition.

Mechanical Properties:
– Tensile Strength: The 13CrMo4-4 steel grade has a minimum tensile strength of 440-590 MPa, ensuring its strong and durable nature.
– Yield Strength: It has a minimum yield strength of 290-390 MPa, providing the necessary resistance against deformation.
– Elongation: The steel grade offers a minimum elongation of 22%, indicating its ability to withstand elongation without breaking.

Chemical Composition:
– Carbon (C): The carbon content in 13CrMo4-4 steel grade is between 0.10-0.17%, contributing to its strength and hardness.
– Silicon (Si): The silicon content is around 0.10-0.35%, providing good surface quality and resistance to oxidation.
– Manganese (Mn): The manganese content is typically between 0.40-0.70%, enhancing the hardenability and strength of the steel.
– Phosphorus (P): Phosphorus content is maintained low at a maximum of 0.025%, ensuring good weldability and minimizing the risk of brittleness.
– Sulfur (S): The sulfur content is limited to a maximum of 0.010% to improve the machinability of the material.
– Chromium (Cr): The chromium content is around 0.70-1.15%, which contributes to the steel’s high-temperature strength, corrosion resistance, and oxidation resistance.
– Molybdenum (Mo): Molybdenum content ranges from 0.45-0.60%, providing excellent mechanical properties at high temperatures, including creep resistance and high thermal conductivity.

Overall, the 13CrMo4-4 steel grade with its strong mechanical properties and well-balanced chemical composition makes it an ideal choice for high-temperature applications where strength, durability, and resistance to oxidation and corrosion are required.
