GB L52952 GB/T 4171 Chemical Element
GB L52952 GB/T 4171 in addition to carbon, steel also contains a small amount of manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) and hydrogen (H). These elements are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements. These impurities have a certain impact on the properties of steel. In order to ensure the quality of steel, the chemical composition of all kinds of steel is strictly stipulated in technical standards.
The main elements proportion is as below:
| Element | Min | Max | Similar |
|---|---|---|---|
| Si | 0.1000 | 0.4000 | - |
| S | - | 0.0400 | - |
| P | 0.0700 | 0.1200 | - |

| C | - | 0.1200 | - |
GB L52952 GB/T 4171 Mechanical Properties
The tensile strength of GB L52952 GB/T 4171 steel is between 570 and 700MPa. The yield strength of this steel is min 195MPa and the elongation after fracture is approximately 12%. The test value of lateral expansion of steel goes up to 22%. The notch impact energy of GB/T 4171 steel plates can reach 34J. The cold bending performance of the steel plates is satisfactory, with the bend radius greater than 4 times the width of the steel plates.
The resistance of GB L52952 GB/T 4171 to damage under load is called its mechanical properties. The mechanical properties of steel materials are the main basis for the design and material selection of parts. The mechanical properties of steel materials will be different with different loading properties (such as tension, compression, torsion, impact and cyclic loads). Common mechanical properties include strength, plasticity, hardness, impact toughness, multiple impact resistance and fatigue limit.
The mechanical properties of GB L52952 GB/T 4171 is in line with GB/T 4171. The main properties as below:
