EN 1.8153 (60SiCrV7) Steel
EN 1.8153 steel is an alloy steel formulated for primary forming into wrought products. 1.8153 is the EN numeric designation for this material. 60SiCrV7 is the EN chemical designation.
It has a very low melting temperature among EN wrought alloy steels. In addition, it has a very low density and can have a moderately high tensile strength.
The properties of EN 1.8153 steel include six common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.8153 steel to: EN wrought alloy steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition
Among alloy steels, the composition of EN 1.8153 steel is notable for containing a comparatively high amount of silicon (Si). Silicon content is typically governed by metallurgical processing concerns, and not its effects on final material properties. However, it does have a modest strengthening effect.
