The 34CrNiMo6 steel grade is known for its superior mechanical properties. Its mechanical strength, toughness, and wear resistance make it a popular choice for various applications.
The technical properties of 34CrNiMo6 steel grade include its hardness, tensile strength, yield strength, and elongation. It has a high hardness level, typically ranging from 20 to 30 HRC (Rockwell hardness scale). The tensile strength of this steel grade is typically around 1000-1200 MPa, making it suitable for high-stress applications. It also exhibits a high yield strength, usually ranging from 800 to 1000 MPa. The elongation of 34CrNiMo6 steel grade is typically around 12-15%, indicating its good ductility.
In terms of chemical composition, the 34CrNiMo6 steel grade consists of various elements that contribute to its superior mechanical properties. It primarily consists of carbon (C), manganese (Mn), chromium (Cr), nickel (Ni), molybdenum (Mo), and silicon (Si). The carbon content is relatively low, typically ranging from 0.30 to 0.38%. The manganese content is usually around 0.5-0.8%.
The chromium content in 34CrNiMo6 steel grade is responsible for its enhanced hardenability and corrosion resistance. It typically ranges from 1.3 to 1.7%. The nickel content enhances the toughness of the steel and provides resistance to external factors such as impact and wear. The nickel content in this steel grade is typically around 1.3-1.7%.
Molybdenum is another important element in the chemical composition of 34CrNiMo6 steel grade. It improves the strength and hardenability of the steel. The molybdenum content in this steel grade is typically around 0.15-0.3%.
Silicon is present in small quantities in this steel grade and helps in improving its strength and hardness. The silicon content is usually around 0.15-0.3%.
By combining these elements in the right proportions, the 34CrNiMo6 steel grade achieves its superior mechanical properties, making it suitable for a wide range of applications in industries such as automotive, aerospace, and machinery.
