1045 Carbon Steel

Description

1045 is a medium-carbon steel known for its good strength, toughness, and wear resistance. It is commonly used in various industrial applications.

Applications

1045 is widely used in machinery parts, shafts, gears, bolts, studs, and other components where high strength and good machinability are required.

Blacksmith Applications

1045 is commonly used as a tool steel, such as hammers, axes, chisels, and other applications where strength and toughness are good.

1045 Forging Temperature

Forging should be done between 1700°F - 2200°F to (927°C to 1204°C), followed by slow cooling in a furnace or insulating material.

1045 Heat Treatment

1045 Annealing Temperature

Annealing is typically performed at 1475°F (802°C) for a sufficient amount of time, followed by slow cooling in the furnace to relieve internal stresses.

1045 Normalizing Temperature

Normalizing can be carried out at 1600°F to 1700°F (871°C to 927°C) for a proper soak time, followed by air cooling.

1045 Hardening Temperature

Hardening is achieved by heating the steel to 1500°F to 1600°F (816°C to 871°C) and then quenching in water, oil, or brine.

1045 Tempering Temperature

Tempering should be performed between 300°F to 700°F (149°C to 371°C) to achieve the desired hardness and toughness.

Machinability

1045 has a machinability rating of 70, indicating good machinability with appropriate cutting tools and techniques.

Weldability

1045 has moderate weldability. Preheating and post-weld heat treatment are often required to minimize the risk of cracking and achieve desired properties.
