4x8ft 1045 Hot Rolled Cold Rolled Medium Mild Steel Hot Rolled Wearing Sheet
 

AISI 1045 steel is a medium tensile steel that is available in black hot-rolled or normalized form. It has a tensile strength of 570-700 MPa and a Brinell hardness of 170-210.

In either normalized or hot-rolled form, AISI 1045 steel has good weldability, machinability, and high strength and impact qualities.

In either normalized or hot-rolled form, AISI 1045 steel has good weldability, machinability, and high strength and impact qualities.

Through-hardening potential of AISI 1045 steel is limited, with only portions of roughly 60 mm in size suggested for tempering and through-hardening. However, depending on conditions such as section size, kind of set up, quenching medium employed, and so on, it may be successfully flame- or induction-hardened in the normalized or hot rolled state to yield surface hardnesses in the range of Rc 54 - Rc 60.

Because AISI 1045 steel lacks appropriate alloying components, it does not react to the nitriding process.

Applications

AISI 1045 is widely used for all industrial applications requiring more wear-resistance and strength. Typical applications of AISI 1045 are as follows:

Heat Treatment

AISI 1045 is subjected to forging, annealing, normalizing, stress-relieving, hardening and tempering processes – each of which is explained in more detail below:

• Forging - Heat to 850°C - 1250°C (1562°F - 2282°F). Hold until the temperature is uniform. Cool in a furnace.

• Annealing - Heat to 800°C - 850°C (1472°F - 1562°F). Hold until the temperature is uniform. Cool in a furnace.

• Normalizing - Heat to 870°C - 920°C (1598°F-1688°F). Hold until the temperature is uniform. Soak for 10 - 15 minutes. Cool in still air.

• Stress-Relieving - Heat to 550°C - 660°C (1022°F - 1220°F). Hold until the temperature is uniform. Soak for 1 hour per 25mm of section. Cool in still air.

• Hardening - Heat to 820°C - 850°C (1508°F - 1562°F). Hold until the temperature is uniform. Soak for 10 - 15 minutes per 25mm of section. Quench in water or brine.

• Tempering - Re-heat to 400°C - 650°C (752°F - 1202°F) as required. Hold until the temperature is uniform. Soak for 1 hour per 25mm of section. Cool in still air.
