Starrett 54976 Low Carbon Steel Flat Stock 3/8 X 6 X 24 in

Product Description

The STARRETT 54976 is a low carbon steel flat stock bar cut to 24 inches long, 6 inches wide, and 3/8 inch thick. It conforms to AISI Type C1018 material specification, a widely used low carbon steel grade valued for its machinability, weldability, and consistent mechanical properties. This flat stock is held to tight dimensional tolerances, making it suitable for precision fabrication work where fitment and flatness matter. Machinists, fabricators, and millwrights reach for this bar stock when building fixtures, brackets, mounting plates, and structural weldments that require reliable base material with predictable behavior during cutting, drilling, and welding.

This flat bar is appropriate for general-purpose industrial and trade fabrication in both shop and field settings. Typical applications include HVAC equipment supports and curbs, plumbing and mechanical equipment bases, electrical enclosure frames, and custom bracket fabrication. The C1018 specification makes it compatible with standard MIG and TIG welding processes and accepts most common surface treatments including painting, powder coating, and plating. Sold as a single piece per package.

Key Features

• AISI Type C1018 low carbon steel for consistent machinability and weldability
• Tight thickness and square tolerance of plus or minus 0.001 inch for precision fit-up
• Width tolerance of plus 0.000 to 0.005 inch ensures controlled stock sizing
• Length tolerance of plus 0.625 inch allows for final trimming to exact dimension
• Ready for welding, drilling, tapping, and surface finishing without pre-treatment

Compatibility

Designed as a general-purpose flat bar for fabrication, structural, and mechanical support applications across HVAC, plumbing, electrical, and industrial trades. No specific equipment model compatibility is stated by the manufacturer.

Installation Notes

Cutting and grinding operations on steel flat stock produce sparks and sharp edges — appropriate PPE including eye protection and gloves is required. Fabricators should deburr all cut edges before handling or assembly. Welding this material should follow standard procedures for low carbon steel per applicable AWS codes. Verify all structural applications meet local building and mechanical code requirements before installation.
