Starrett 57251 Steel Flat Stock 24x10x5/16 in Aisi C1018

Product Description

The STARRETT 57251 is a low carbon steel flat stock bar cut to 24 x 10 x 5/16 inches and manufactured to AISI Type C1018 material specification. This flat bar is a general-purpose structural and fabrication stock used in metalworking, machine shops, and maintenance applications. The C1018 designation indicates a mild, low carbon steel with good machinability and weldability, making it suitable for a wide range of cutting, drilling, and forming operations. Thickness and square tolerances are held to plus or minus 0.001 inch, and width tolerance runs plus 0.000 to 0.015 inch, reflecting consistent dimensional control appropriate for precision layout and fabrication work.

This flat stock is used in industrial fabrication, general machining, and maintenance repair operations across commercial and light industrial settings. Typical applications include brackets, spacers, fixtures, shims, and structural support components. It is commonly worked by machinists, fabricators, millwrights, and maintenance technicians. The 24-inch length and 10-inch width provide a substantial blank for layout and cutting to final dimensions on the shop floor.
