Alleima® 20C is a hardened and tempered carbon steel characterized by:
High strength
High fatigue strength under bending and impact stress
Low level of non-metallic inclusions
Good wear resistance
Compressor valve steel in Alleima® 20C has excellent surface finish, good dimensional tolerances and good flatness.
Applications
Valve production
Valves made from Alleima® 20C compressor valve steel should be produced with fatigue properties in mind, in order to make full use of the excellent material properties.
Valve types:
Flapper valves
Reed valves
Check valves
Forms of supply
Strip steel is supplied in labelled coils, or on labelled plastic spools, depending on weight and size. The label details the steel grade, heat, lot and coil number, and nominal size, allowing full material traceability. Material is protected against rust with oil.
Coils are wrapped in paper and packed in wooden cases. For overseas shipment, coils are also sealed in a plastic bag containing silica gel. Net and gross weights are marked on the case. Customized properties, dimensions and tolerances can be supplied on request.
