ISO 3183 PSL2 Grade L290MS Material Mechanical Properties
The mechanical properties of ISO 3183 PSL2 Grade L290MS are determined through the combination of chemistry, heat treatment, and mechanical processing. Generally speaking, the mechanical properties of ISO 3183 PSL2 Grade L290MS can be improved by increasing the levels of alloying elements, such as carbon and manganese. ISO 3183 PSL2 Grade L290MS is often classified as a medium carbon steel with a yield strength of at least 250 MPa (36 ksi). It is also classified as an alloy steel, which means it has a higher level of strength than low carbon steel and greater wear resistance than stainless steel. Generally, ISO 3183 PSL2 Grade L290MS has excellent weldability and is suitable for cold forming and bending.
The mechanical properties of the ISO 3183 PSL2 Grade L290MS steel are as follows:
