ISO 3183 PSL2 Grade X46MS Material Mechanical Properties
The mechanical properties of ISO 3183 PSL2 Grade X46MS are determined through the combination of chemistry, heat treatment, and mechanical processing. Generally speaking, the mechanical properties of ISO 3183 PSL2 Grade X46MS can be improved by increasing the levels of alloying elements, such as carbon and manganese. ISO 3183 PSL2 Grade X46MS 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 X46MS has excellent weldability and is suitable for cold forming and bending.
The mechanical properties of the ISO 3183 PSL2 Grade X46MS steel are as follows:

ISO 3183 PSL2 Grade X46MS Material Machining Technology
The first step in machining ISO 3183 PSL2 Grade X46MS is to choose the correct cutting tool and machining setup. In order to achieve an adequate cutting speed, tools with a high number of cutting edges should be selected, preferably between 7000 and 12000 RPM. To reduce the risk of chip formation and tool wear, hard-faced cutting tools with a certain degree of flexibility should be used.
