A830/C1045 steel plate refers to a medium-carbon steel plate that conforms to the ASTM A830/A830M specification. The ASTM A830/A830M specification covers structural quality carbon steel plates with improved toughness.

C1045 is a widely used grade of medium-carbon steel known for its good strength, wear resistance, and machinability. It contains about 0.45% to 0.55% carbon, making it suitable for various applications that require moderate strength and hardness.

The A830/C1045 steel plate is typically hot-rolled, but it can also be cold-rolled or heat-treated for specific applications. The manufacturing process and heat treatment can affect the mechanical properties of the steel, such as its hardness, tensile strength, and impact resistance.

A830/C1045 steel plate finds applications in a range of industries, including machinery parts, shafts, gears, bolts, studs, and general engineering components. It is often used in applications that require moderate to high strength and toughness while maintaining good machinability.

It’s worth noting that the designation “A830/C1045” indicates compliance with the ASTM A830/A830M specification for carbon steel plates, while “C1045” refers to the specific grade of medium-carbon steel within that specification.
