EN 1.8550 (34CrAlNi7-10) Nitriding Steel
EN 1.8550 steel is an alloy steel formulated for primary forming
into wrought products. Cited properties are appropriate for the
quenched and tempered condition. 1.8550 is the EN numeric
designation for this material. 34CrAlNi7-10 is the EN chemical
designation.
It has a moderately low melting temperature among EN wrought alloy
steels. In addition, it has a moderately high electrical
conductivity and a moderately low thermal conductivity.
The graph bars on the material properties cards below compare EN
1.8550 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.
1.8550 is intended for work at elevated temperatures in an
environment that requires high sliding properties, corrosion,
temperature, abrasion, and fatigue resistance. Steel with the
addition of Nickel and Aluminum used in the energy, machinery, and
automotive industries for large cross-sections elements in the heat
treated condition. The products are used in the manufacture of
screws, rods, cylinders, pistons, gears, extruders, and rings,
which do not require welding.
