Product Description
China Supplier AISI 1055 55 S55C C55 EN9/070M55 Hot/Cold Rolled Carbon Steel Plate
1: 1055 steel introduction
1055 steel is an unalloyed medium carbon engineering steel which has 0.52%-0.6% Carbon as per EN10083 standard.It will obtain high hardness and high strength after hardening due to the relatively high carbon content,and also can be flame or induction hardened to surface hardness Min 58HRC.C55 steel is generally supplied in an untreated or normalised condition.

| Application | 1055 is a medium carbon steel suitable for various type of applications where high strength is needed.It is used for components of small cross section requiring low tensile strength, and heavy forgings in the normalized condition for automotive and general engineering such as axles, clutch members, shafts, pressed and punched parts, piston rods and gear racks. | |
6: HEAT TREATMENT
ANNEALING
As mentioned above, forgings may be transferred to a furnace at a temperature that may approximate to the forging finishing temperature. The full annealing cycle of this grade is a soak at a temperature of 1450-1600oF (790-870oC) cooling to 1200oF (650oC) at 50oF (28oC) per hour, soaking and subsequently air cooling.
NORMALIZING
This steel will on occasion require normalizing prior to further heat treatment such as hardening and tempering. This is carried out at a temperature of 1650oF (900oC) followed by air cooling.
HARDENING
This steel is austenitized at 1475-1550oF (800-845oC) followed by water or oil quench depending upon section size and complexity.
TEMPERING
This steel will be tempered at a temperature to give required mechanical properties, based on past experience. It should be noted that there is a danger of temper brittleness in the temperature range of 500-600oF (260-315oC.)
7: Delivery condition
For hot forged bar, usually the delivery condition is hot forged, annealed/QT, rough turned/Black surface.
For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
For Cold Drawn bar, usually the delivery condtion is cold drawn, annealed/QT, peeled/black surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed, milled/black surface
For hot forged plate, usually the delivery condition is hot forged, normalized/annealed, milled/black surface.
