Value Collection 24924 Alloy Steel Flat Stock 4142

Product Description

The VALUE COLLECTION 24924 is a Type 4142 alloy steel pre-hardened flat stock bar intended for tooling, fixturing, die components, and general machining applications. Measuring 72 inches long, 2.5 inches wide, and 0.25 inches thick, it arrives pre-hardened for added wear resistance and dimensional stability. The 4142 chromium-molybdenum alloy composition provides higher tensile strength and toughness compared to standard low-carbon flat bar. Machinists, tool-and-die makers, and fabricators working on structural or wear-part applications will find this stock suitable for secondary machining, grinding, and forming operations where consistent hardness and close dimensional tolerances are required.

This flat stock is used in industrial and commercial fabrication shops, tool rooms, and maintenance environments. Typical applications include wear plates, die shoes, jigs, fixtures, and machine component blanks. At 0.25 inches thick and 2.5 inches wide, it suits medium-duty structural and tooling uses. The 72-inch length allows multiple parts to be cut from a single bar, reducing material waste. This item is sold individually as a single-piece unit.

Key Features

• Type 4142 chromium-molybdenum alloy steel for elevated tensile strength and toughness
• Pre-hardened condition provides consistent hardness without additional heat treatment
• Length tolerance of plus 1.00 inch, minus 0.000 inch ensures full usable length
• Width tolerance of plus 0.005 inch for close-fit applications
• Thickness tolerance of plus or minus 0.002 inch for precision machining stock
• Square tolerance of 0.002 inch supports accurate layout and fixturing

Compatibility

Designed as a general-purpose pre-hardened flat bar suitable for tool-and-die, fixture, and wear-component fabrication applications requiring 4142 alloy steel stock in this size range.

Installation Notes

Cutting, drilling, and grinding of pre-hardened 4142 alloy steel requires tooling rated for hardened materials; standard high-speed steel bits are not recommended. Carbide-tipped or coated tooling and appropriate cutting fluids should be used to preserve tool life and dimensional accuracy. Secure the bar firmly in a vise or fixture before any machining operation. Always wear appropriate personal protective equipment when cutting or grinding alloy steel stock.
