MATERIAL DESCRIPTION

EN 1.8509 (41CrAlMo7-10) Nitriding Steel

 

EN 1.8509 steel is an alloy steel formulated for primary forming into wrought products. Cited properties are appropriate for the quenched and tempered condition. 1.8509 is the EN numeric designation for this material. 41CrAlMo7-10 is the EN chemical designation.

It has a fairly low thermal conductivity among EN wrought alloy steels. In addition, it has a moderately low melting temperature and a very high tensile strength.

The graph bars on the material properties cards below compare EN 1.8509 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 of 41CrAlMi7 / 1.8509 Alloy Steel

 

Among alloy steels, the composition of EN 1.8509 steel is notable for including aluminum (Al). Aluminum is used to control grain size and to deoxidize. Deoxidizing is required to control the effects of some other alloying elements.

PRODUCTS APPLICATION

41CrAlMo7 Application:

41CrAlMo7 Nitriding Steel is suited for applications that required excellent resistance to wear and abrasion. Typical applications include connecting rods, small extruders, valve stems, dies. It is widely used in the automotive, textile and general engineering industries. Suitable for applications requiring a resistance to wear, it is also suitable for other applications such as brick press plates, clutch plates, gudgeon, track and shackle pins.
