Understanding the Mechanical Properties of C35 Steel Grade

The C35 steel grade is a medium carbon steel with a chemical composition of 0.32-0.39% carbon, 0.50-0.80% manganese, 0.04% phosphorus, and 0.05% sulfur. It also contains small amounts of silicon, copper, and other elements.

The mechanical properties of C35 steel grade are as follows:

1. Tensile strength: The tensile strength of C35 steel grade ranges from 550 to 650 MPa. This high tensile strength allows it to withstand heavy loads and resist deformation under stress.

2. Yield strength: The yield strength of C35 steel grade is approximately 280-320 MPa. This is the maximum stress that the steel can withstand before it starts to deform permanently. It is an important parameter for design calculations and determining the structural integrity of a component.

3. Elongation: The elongation of C35 steel grade is around 22%, which means that it can undergo a significant amount of plastic deformation before failure. This property makes it suitable for applications that require high impact resistance and ductility.

4. Hardness: The hardness of C35 steel grade is typically in the range of 170-210 HB. This indicates its resistance to localized deformation, such as indentation or scratching. It can be further enhanced by heat treatment processes.

5. Impact strength: C35 steel grade has good impact strength, which means it can absorb energy without breaking or fracturing easily. This property is important for applications that involve sudden and heavy impacts, such as construction and automotive components.

6. Fatigue strength: C35 steel grade has moderate fatigue strength, allowing it to withstand repeated cyclic loading without experiencing failure. However, it is important to consider fatigue design guidelines to ensure the longevity and reliability of the components.

In conclusion, the mechanical properties of C35 steel grade, including its high tensile strength, moderate yield strength, good elongation, hardness, impact strength, and fatigue strength, make it suitable for various applications, such as shafts, gears, bolts, and structural components. Understanding these properties is crucial for engineers and designers to make informed decisions and select the appropriate steel grade for specific applications.
