1045 Steel Round Bar Material SAE 1045 SAE 1045 Steel Manufacturer
SAE 1045 steel is an unalloyed medium carbon grade under the standards of the American Society of Automotive Engineers(SAE).
SAE 1045 steel is generally delivered in an unheated or normalized conditon.When delivered in the normalized state, SAE 1045 steel has good cold and hot workability and average strength, so it is widely used in machinery manufacturing.
SAE 1045 steel can obtain good mechanical properties through quenching and tempering heat treatment.After QT, the material properties have been greatly improved and can be used to manufacture various important structural parts.

SAE 1045 STEEL HEAT TREATMENT
SAE 1045 Steel Normalizing
Normalizing temperature:830-880℃
Holding time:Depending on the workpiece size and loading capacity.According to our experience,if the size of SAE 1045 steel is small, the holding time is short. As the size becomes larger, the corresponding holding time will be extended.However, it is not that the longer the holding time, the better the normalizing effect. On the contrary, too long holding time will lead to coarse grains and overburning of the material, which will eventually affect the properties of the material.
Cooling method: air cooling.Rapid cooling effect can also be achieved by spraying water mist.It should be noted that too fast cooling is not advisable, because it is easy to cause cracking of the material.
According to our experience,Normalizing is an important heat treatment process for SAE 1045 steel.First, for general purpose parts, normalizing can be used as the final heat treatment process for SAE 1045 steel to meet the specified properties.
Secondly, it can be used as a pre-preparation process for the final quenching and tempering heat treatment of SAE 1045 steel, the purpose is to refine the grain and homogenize the structure, and prepare the structure for the final heat treatment.

| 670-720 | ≥340 | 15-18 | 45-50 | ≥50 | 170-240 |
SAE 1045 Steel Annealing
According to our experience, the purpose of annealing heat treatment for SAE 1045 steel is usually to soften the surface hardness for machining.
The annealing temperature of SAE 1045 steel is generally controlled at 820-840°C.After a sufficient holding time, the material can be cooled to room temperature in the furnace.The measured surface hardness of the material is usually lower than 200HBW, which is very easy for subsequent processing.
SAE 1045 Steel Quenching & Tempering(QT)
When SAE 1045 steel is applied to important structural parts, such as connecting rods, gears, bolts and shafts working under alternating loads, the performance of SAE 1045 steel cannot meet the requirements after normalizing heat treatment.At this time, we need to consider quenching and tempering heat treatment of SAE 1045 steel, which can achieve good comprehensive mechanical properties.
Quench Temperature:820-840°C
Quench Medium: Water/Oil
Quenching Hardness:55-60HRC
Tempering temperature:500-540°C
Tempering Hardness: 28-32HRC
