SAE AISI 1045 Steel
ASTM SAE AISI 1045 steel is one of the commonly used medium carbon
steels with an average carbon content of 0.45%, medium tensile
properties, good strength, toughness and wear resistance. It can be
treated by annealing, flame treatment or induction hardening.
C1045 is also known as 1045 cold rolled steel (cold worked), and
1045 hot rolled steel is known as 1045 HR.
Chemical Composition of AISI1045 Steel Pipe
| AISI ASTM 1045 Chemical Composition (%) |
| Steel Grade (UNS) | C | Mn | P (≤) | S (≤) |
| 1045 (G10450) | 0.43-0.50 | 0.60-0.90 | 0.040 | 0.050 |
Mechanical Properties
1045 material mechanical properties are listed in the following
table including tensile strength, yield strength, elongation,
reduction and hardness, etc.
| 1045 carbon steel mechanical properties (sizes ranging: 19-32 mm) |
| Steel (UNS) | Tensile strength (Mpa) ≥ | Yield strength (Mpa) ≥ | Elongation in 50 mm, % ≥ | Reduction in area, % ≥ | Hardness (HB) | Processing, condition or treatment |
| AISI SAE 1045 (G10450) | 565 | 310 | 16 | 40 | 163 | Hot rolled |
| 625 | 530 | 12 | 35 | 179 | Cold drawn |
| 585 | 505 | 12 | 45 | 170 | Annealed, cold drawn |
Normalizing
1045 normalizing temperature range is 830-900 °C and the typical
normalizing temperature is 860 °C.
Austenitizing
The austenitizing temperature for SAE 1045 induction hardening
carbon steel is 800-845 °C.
Full Annealing
The annealing temperature for AISI 1045 carbon steel is from
790-870 °C, cooling cycle from 790 to 650 °C at a rate of 28 °C/h
in furnace, and can get the HBW hardness range from 156 to 217.
(Suitable for forgings with a section thickness of up to 75 mm. For
the section up to 25 mm thick, the temperature time is usually at
least 1 hour; for each 25 mm thick increase, 0.5 h is added.)
Hardening
The austenitizing heating at 845 °C, the quenching medium is water
or brine, and the workpiece with wall thickness ≤6.35 mm is oil
quenched, and the hardness should be no less than 55 HRC.
Welding
For the thickness of the weldment is ≤13mm, the preheating and
interpass temperature is at least 150 °C under low hydrogen
condition, other than low hydrogen, the temperature is minimum 177
°C, heat treatment is required after welding and the temperature
range is 590-675 °C.
For the weldment thickness (t) 13<t≤100mm, the preheating and
interpass temperature is ≥205 °C (under low hydrogen condition),
≥230 °C (except low hydrogen), and the postweld heat treatment
temperature is 590-675 °C.

Applications
AISI SAE 1045 material is widely used in industrial applications
where higher wear resistance and strength are required, typical
applications including: Light gears, shafts, axles, spindles, pins,
guide rods, connecting rods, bolts, worms, crankshafts, machine
components, etc.
