Model EN9 / C55 -Carbon Steel
EN9 carbon steel is a medium carbon metallic grade generally furnished within the as-rolled and forged circumstance. It can be flame or induction hardened to provide a excessive floor hardness with awesome put on resistance for a carbon metallic grade. Availability of EN9 bars in full lengths or can be cut according to customer requirements. EN9 carbon spherical, rolled round, forged round, rolled flat, forged flat, sheets and plates; bandsaw cut metal can be provided as per required sizes.
Forms available in market:
- Round bar.
- Flat bar.
- Heavy blocks.
- Heavy wall thickness pipe
- Plates
- Sheets
- Strips
Forging Properties of EN9 Steel:
Preheat the component carefully, then raise the temperature to 1100°C for forging. Do not forge below 850°C. After forging cool slowly, preferably in a furnace.
Heat treatment of EN9 Steel:
Tempered the EN9 metallic element immediately after quenching even as nevertheless hand warm. Re-warmth to the tempering temperature then soak for one hour in keeping with 25 millimetre of overall thickness (2 hours minimum) Cool in air. For many applications tempering of EN9 will be between 550-660°C.
Hardening of EN9 Steel:
Carbon steel EN9 or 070M55 can be tempered at a heat of between 550°C to 660°C,heating for about 1 hour for every inch of thickness, then cool in oil or water.
Tempering OF EN9 Steel:
Quenching: Temper the EN9 steel metal component right away after quenching whilst still hand warm.
Tempering: Re-heat to the tempering temperature then soak for one hour according to 25 millimeters of general thickness .
Normalizing:For most applications tempering of EN9 could be among 550-660°C.Then cooled in air.
