Meet the Demands of Challenging Environments with 13CrMo4-4 Steel

13CrMo4-4 steel is a low-alloy steel that is commonly used in industries such as petroleum, chemical, and power generation due to its ability to meet the demands of challenging environments. This steel is specifically designed to withstand high temperatures and pressures while maintaining its mechanical properties and chemical composition.

Mechanical Properties:
– Tensile Strength: The tensile strength of 13CrMo4-4 steel is typically between 450 and 600 MPa.
– Yield Strength: The yield strength of this steel is typically between 275 and 355 MPa.
– Elongation: The elongation of 13CrMo4-4 steel is typically around 22%.
– Impact Toughness: This steel exhibits good impact toughness, allowing it to withstand sudden or dynamic loads without fracturing.
– Hardness: The hardness of 13CrMo4-4 steel is usually between 130 and 180 HB.

Chemical Composition:
– Carbon (C): The carbon content in this steel is typically between 0.08 and 0.18%, providing good weldability and forming properties.
– Chromium (Cr): The chromium content in 13CrMo4-4 steel is between 0.70 and 1.15%, which enhances the steel’s corrosion resistance and high-temperature strength.
– Molybdenum (Mo): The molybdenum content in this steel is between 0.40 and 0.60%, providing increased strength and creep resistance at elevated temperatures.
– Silicon (Si): The silicon content is typically between 0.15 and 0.50%, which improves the steel’s resistance to oxidation and scaling.
– Manganese (Mn): The manganese content is between 0.40 and 1.00%, contributing to the steel’s hardenability and strength.
– Phosphorus (P) and Sulfur (S): The maximum content of phosphorus and sulfur in this steel is limited to 0.025% each, ensuring good weldability and avoiding brittleness in the heat-affected zone.

Overall, the combination of its mechanical properties and chemical composition makes 13CrMo4-4 steel an ideal choice for applications that require high-temperature and pressure resistance, corrosion resistance, and good weldability.
