ASTM A752M A752 Grade 4028 chemical
ASTM A752M A752 Grade 4028 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 | 0.1500 | 0.3000 | - |
| S | 0.0350 | 0.0500 | - |

ASTM A752M A752 Grade 4028 mechanical
The resistance of ASTM A752M A752 Grade 4028 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.
