Product Description
1: 1018 steel introduction
SAE AISI 1018 steel is one of the commonly used low carbon steels. It is usually used as carburized steel. Since most of the 1018 carbon steel is produced by cold drawing, this cold rolled steel is called C1018 (1018 cold rolled steel). AISI C1018 steel (1018 CRS) has good weldability, surface hardening quality, higher mechanical properties and better machinability. Cold drawing increases tensile strength, yield strength, torsional strength, surface hardness and wear resistance, but reduces ductility.
ASTM AISI SAE 1018 hot rolled steel is also known as 1018 HR, and has good toughness, strength, ductility, formability, weldability and workability.

4: 1018 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: HEAT TREATMENT
A significant amount of this grade of steel is used in the as- forged condition, since its machinability in this condition has been found to be better than that in the normalized condition.
Little is to be gained, at this carbon level, by a quenching treatment.
At this carbon level, annealing after forging may not be necessary, and depending upon the hardness after forging and the complexity of the part being forged, machining may be carried out on the as-forged parts. If parts are of complex shape and hence there are structural variations throughout the part, then normalizing is in order.
NORMALIZING
Normalizing is seldom carried out on carbon contents at this level, but may be used prior to surface hardening. The normalizing temperature range for this grade is typically 1650-1700oF (900 - 925oC.) followed by air cooling.
HARDENING
This grade of steel is not normally subjected to hardening and tempering treatments as the hardness obtained from such treatments would not warrant their being performed. Carburizing might be carried out at 1620-1690oF (880-920oC,) and carbonitriding at 1470 -1600oF (800-875oC.)
Hardening of the carburized case would be performed at 1430-1500oF (780-820oC) followed by a water quench and a tempering treatment at 300-400oF (150-200oC) to improve case toughness with a minimum effect on its hardness. Case hardness values of Rc 58 may be obtained on carburized C1018.
7: Delivery condition

For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
