This Nutec42 Pre-hardened Regular Tolerance (Precision Tolerance) Ground Flat Stock (Gauge Stock) is made by Precision Marshall Steel Company. The steel type is AISI 4142 modified steel, pre-hardened to 26-34 Rc (261-321 Brinell).

It is normalized and tempered in a machinable condition of approximately 85% compared to 1.00% carbon steel. It is useful in applications requiring a lower hardness and less wear resistance than a fully heat treated tool steel but can be flame-hardened where a greater hardness is needed.

The standard nominal sizes are ground to a satin finish on four sides, held to tight tolerances in dimensions and squareness, and ready for layout. Each piece is lightly coated with rust-preventive oil and individually packaged in a vapor-resistant envelope which has the size and steel type clearly marked. At least one end is painted red for easier identification of the steel type.

The Thickness |T| tolerance is ±.001". The Width |W| tolerance is +.000/.005, when W > T and the profile is rectangular. When W=T the profile is square and the width tolerance is ±.001". The 18" Length |L| tolerance is +.125/.250". The 36" Length |L| tolerance is +.250/.500".

The available thicknesses are 1/16 to 1 inches. The available widths are 3/16 to 10 inches. Please contact us if you need a different size, or if you need us to make any alterations.
