Useful

AISI 1045 is a medium carbon structural steel with good cold and hot workability, as well as good mechanical properties. This type of steel is widely used in the industrial machinery manufacturing industry, and due to its low price and wide supply, it is used in a variety of different products and applications.

Wire, forgings, plates, and round steel

Wire: AISI 1045 steel wire is commonly used to manufacture various mechanical components such as bolts, screws, and rivets, as well as in situations where high strength and toughness are required.

Forging: 1045 steel can be forged, suitable for manufacturing forgings such as connecting rods, steering arms, front axles of freight cars, and moving wheels. Forgings require appropriate heat treatment processes to achieve appropriate cutting performance.

Sheet metal: Sheet metal can be used for structural components such as machine bases and frames, as well as in applications that need to withstand large loads.

Round steel: AISI 1045 round steel is widely used in the manufacturing of mechanical components such as shafts, gears, and pins, and is favored for its excellent mechanical properties.

Heat treatment process

The heat treatment process of AISI 1045 steel mainly includes:

Normalization: By heating and subsequent rapid cooling, finer grain structures are obtained and the comprehensive mechanical properties of the material are improved.

Annealing: Heating to a certain temperature and slowly cooling to obtain softer and easier to process materials.

Quenching: Heating steel to a certain temperature and rapidly cooling it to obtain a martensitic structure with higher hardness and strength.

Tempering: The quenched steel is tempered at a lower temperature to reduce quenching stress, restore toughness, and adjust hardness.

The specific heat treatment temperature and time may vary depending on the required performance and application requirements. For example, AISI 1045 steel is usually heated between 400 ° C and 650 ° C, maintained for a certain period of time as needed until the temperature of the entire section is uniform, and then cooled.

International substitutes

International alternatives to AISI 1045 steel include but are not limited to:

National standard 699:45 # steel

EN 10083-2: C45/1.0503 and C45E/1.1191

JIS G4051：S45C

BS 970：EN8

080M40: Steel under specific conditions

These alternative materials must meet the corresponding economic, physical, and chemical requirements to ensure that they can replace AISI 1045 steel in specific applications.
