Introduce

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.
