AISI 1045 |45 |S45C Steel Plate

AISI 1045 steel is a steel grade in the United States, known as 45 steel in China, and belongs to medium carbon steel. It has a tensile strength of 570 – 700 MPa and a Brinell hardness ranging between 170 and 210.

What is AISI 1045 Steel Plate?

AISI 1045 steel is a high-quality medium-carbon structural steel with a carbon content between 0.43% and 0.50%. It corresponds to the Chinese standard: 45, the Japanese standard: S45C, and the German standard: C45. This steel offers good mechanical properties, wear resistance, and processability, making it widely used in engineering and mechanical processing fields, especially in molds, tools, garden tools, and more.

Overview:

• The surface treatment of the steel plate, whether cold or hot-rolled.
• 1045 steel, a carbon structural steel, belongs to the category of mechanical steel.
• After heat treatment, its hardness, strength, and abrasion resistance are better than Q235.
• ZGT Steel supports various hardness customizations and OEM processing services.
• Healthy inventories of AISI 1045 steel plate are maintained in all ZGT® Steel distribution centers.
• Ability to be riveted, bolted or welded.

Benefits of AISI 1045 Steel Plate

In the hot-rolled or normalized condition, AISI 1045 is considered to have reliable machinability. Due to its low production cost and relatively soft texture, it is easy to manufacture (manual forging, pressing, or machining can all be used), making it especially suitable for tool types and optimal material for tools.
