Starrett 55019 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 55019 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches long, 1-1/4 inches wide, and 3/4 inch thick, and weighs approximately 6.38 pounds. C1018 is a general-purpose low carbon steel known for its consistent machinability, weldability, and surface finish response — making it a standard choice across fabrication, maintenance, and repair applications. Dimensional tolerances are held tight: thickness and square tolerance are both plus or minus 0.001 inch, width tolerance is plus 0.000 to 0.005 inch, and length tolerance is plus 0.625 inch. This stock is sold as individual pieces.

This flat stock is suited for use in machine shops, tool rooms, and general metal fabrication settings. Typical applications include fixture components, spacers, wear plates, keys, and structural support members in light-duty assemblies. C1018 flat bar is commonly worked by machinists, millwrights, pipefitters, and maintenance technicians who need a reliable, consistent steel bar that machines cleanly and accepts welds without special preheat in most standard thicknesses.

Key Features

• AISI Type C1018 low carbon steel for consistent machinability and weldability
• Tight thickness tolerance of plus or minus 0.001 inch for precise fit-up
• Width tolerance of plus 0.000 to 0.005 inch minimizes oversize interference
• 24-inch length with plus 0.625 inch length tolerance provides cutting stock for multiple parts
• 3/4-inch thickness suits moderate-load structural and mechanical applications
• Sold in single-piece quantity with no multi-piece minimum requirement

Compatibility

Designed as a standard AISI C1018 low carbon steel flat bar for general fabrication, maintenance, and repair use where C1018 or equivalent low carbon steel flat stock is specified.

Installation Notes

Cutting, drilling, and finishing of steel flat stock should be performed by qualified machinists or fabricators using appropriate tooling and personal protective equipment. Secure the workpiece properly before any cutting or machining operation. When welding C1018 steel, follow applicable AWS welding procedures and inspect joint fit-up before weld passes. Deburr all cut edges before handling or installing finished parts.
