Discover the Unique Properties of A648-12 Steel Grade

The chemical composition of A648-12 steel grade typically includes the following elements:

– Carbon (C): 0.15%
– Silicon (Si): 0.25%
– Manganese (Mn): 1.20%
– Phosphorus (P): 0.04%
– Sulfur (S): 0.05%
– Chromium (Cr): 1.00%
– Molybdenum (Mo): 0.30%

These elements contribute to the steel’s overall properties and performance.

In terms of mechanical properties, A648-12 steel grade offers the following unique properties:

– Tensile Strength: The steel has a tensile strength of 648 MPa (94,000 psi), which means it can withstand high amounts of stress and tension before breaking.
– Yield Strength: The yield strength of A648-12 steel grade is 415 MPa (60,200 psi). This indicates the steel’s ability to resist deformation under stress and return to its original shape after the load is removed.
– Elongation: A648-12 steel has a minimum elongation of 12%. This measure shows the steel’s ability to stretch or extend before it fractures. Higher elongation values typically indicate better ductility and formability.
– Hardness: The steel grade has a maximum hardness of 217 Brinell hardness (HB). This measurement quantifies the material’s resistance to indentation or scratching. A higher hardness value denotes increased strength and wear resistance.

A648-12 steel grade typically complies with the ASTM A648/A648M standard. The standard outlines the requirements and testing methods for continuously cast carbon steel blooms, billets, and slabs.

The corresponding A648-12 steel grade is often used in various industrial applications that require high tensile strength, good yield strength, and sufficient hardness. It can be employed in the manufacturing of structural components, machinery parts, automotive parts, and other heavy-duty equipment.
