Grades And Thickness For Aisi 1045 Cold Rolled Steel Sheet Coil Manufacturers Prices
AISI 1045 steel is a medium tensile steel supplied in a black hot-rolled or normalized condition. It has a tensile strength of 570 - 700 MPa and Brinell hardness ranging between 170 and 210.
AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition.
AISI 1045 steel has a low through-hardening capability with only sections of around 60 mm in size being recommended as suitable for tempering and through-hardening. However, it can be efficiently flame- or induction-hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 - Rc 60 based on factors such as section size, type of set up, quenching medium used etc.
AISI 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process.

Machining
Looking for equipment to analyze your metals?
Let us source quotes for you for X-Ray Fluorescence Analyzers, Optical Emission Spectrometers, Atomic Absorption Spectrometers or any other analysis instrument you are looking for.
AISI 1045 steel has good machinability in a normalized or hot-rolled condition. Based on the recommendations given by the machine manufacturers, operations like tapping, milling, broaching, drilling, turning and sawing can be carried out on AISI 1045 steel using suitable feeds, tool type, and speeds.
Welding
AISI 1045 steel is readily welded when the correct procedure is followed, but welding AISI 1045 steel in through-hardened, tempered and flame- or induction-hardened conditions is not recommended. Low hydrogen electrodes are preferred for welding AISI 1045 steel.
The workpiece is:
Pre-heated at 200°C–300°C (392°F - 572°F);
maintained at the same temperature during welding;
cooled slowly using sand or ashes; and
stress relieved at 550°C - 660°C (1022°F - 1220°F).
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.
Applications
AISI 1045 is widely used for all industrial applications requiring more wear-resistance and strength. Typical applications of AISI 1045 are as follows:
Gears | Pins | Rams |
Shafts | Rolls | Sockets |
Axles | Spindles | Worms |
Bolts | Ratchets | Light gears |
Studs | Crankshafts | Guide rods |
Connecting rods | Torsion bars | Hydraulic clamps |
