In addition to its mechanical properties, the chemical composition of 080M15 plays a crucial role in ensuring its performance and durability in demanding environments.

Mechanical Properties:

080M15 steel grade exhibits a tensile strength of approximately 430-580 N/mm², making it suitable for applications that require moderate strength. Its yield strength is typically around 200-330 N/mm², indicating the amount of stress the steel can withstand without permanent deformation. The elongation at break for this steel grade is commonly in the range of 17-27%, highlighting its excellent ductility and ability to deform without fracturing.

The impact strength of 080M15 steel is also noteworthy, with a Charpy V-notch impact energy value of around 52-78 Joules at room temperature. This indicates the ability of the material to absorb energy during impact, making it suitable for structures subjected to dynamic loads.

Technical Properties:

Apart from its mechanical properties, 080M15 steel grade possesses certain technical properties that are crucial for its performance in construction and engineering. It has good weldability, allowing for easy and efficient joining of components during fabrication. This enables the construction of complex structures and assemblies without compromising the integrity of the material.

Furthermore, 080M15 steel exhibits excellent machinability, making it easy to shape and form into desired components. This property is especially beneficial in engineering applications where intricate parts need to be manufactured with precision.

Chemical Composition:

The chemical composition of 080M15 steel grade is as follows:

– Carbon (C): 0.10-0.18%
– Silicon (Si): 0.10-0.35%
– Manganese (Mn): 0.30-0.60%
– Phosphorus (P): 0.05% max
– Sulfur (S): 0.05% max

These elements contribute to the overall properties of the steel. The low carbon content ensures good weldability and promotes strength and toughness. Silicon and manganese enhance its hardenability and contribute to the overall strength and machinability. The limited presence of phosphorus and sulfur helps maintain good weldability and prevent brittleness.
