Starrett 57252 Steel Flat Stock 5/16x12x24 in C1018

Product Description

The STARRETT 57252 is a low carbon steel flat stock bar measuring 5/16 inch thick by 12 inches wide by 24 inches long, manufactured to AISI Type C1018 specification. It is a general-purpose cold-finished steel flat used in fabrication, machining, layout work, and structural applications. The stock ships at a weight of 25.5 pounds and is held to tight dimensional tolerances: thickness and squareness are controlled to plus or minus 0.001 inch, width to plus 0.000 to 0.015 inch, and length to plus 0.625 inch. These tolerances make the stock suitable for applications requiring consistent geometry without additional surface grinding.

This flat stock is suited for machine shops, maintenance and repair operations, fabrication shops, and industrial facilities requiring raw steel bar stock for cutting, welding, or machining into finished components. AISI C1018 is a low carbon grade with good machinability and weldability, commonly used for brackets, fixtures, plates, keys, and general structural parts. It is appropriate for both one-off prototyping and small production runs where a 24 by 12 inch plate provides sufficient material yield.

Key Features

• AISI Type C1018 low carbon steel construction for good machinability and weldability
• Thickness and squareness tolerance held to plus or minus 0.001 inch for dimensional consistency
• Width tolerance of plus 0.000 to 0.015 inch
• Length tolerance of plus 0.625 inch
• Single-piece packaging with a minimum order quantity of one unit

Compatibility

Designed as a standard AISI C1018 low carbon steel flat bar suitable for general fabrication, machining, and structural applications where cold-finished flat stock of this grade and size is specified.

Installation Notes

Cutting, drilling, or welding of steel flat stock should be performed by qualified machinists or fabricators following applicable shop safety procedures. Use appropriate personal protective equipment including eye protection and gloves when handling cut edges. Deburr all cut surfaces before assembly to avoid injury and to ensure proper fit. Store flat stock horizontally on a flat surface to prevent warping.
