This Marshallcrat Regular Precision Tolerance Ground Flat Stock (Gauge Stock) is made by Precision Marshall Steel Company. The steel type is AISI C-1018. It is a finegrained, vacuum-degassed carbon steel. It is easily machined, has excellent weldability. It responds uniformly to case hardening. The manganese content provides greater strength and hardness compared to many other carbon steels. It is often used in its natural state for such applications as backup plates, stripper plates, punch pads and machine parts. As a case hardened material, it is used for jigs, fixtures, cams and patterns.

The standard nominal sizes are ground to a satin finish on four sides, free of decarburization, 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 yellow 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 Length |L| tolerance is +.188/-.375".

The available thicknesses are 1/16 to 2-1/2 inches. The available widths are 3/16 to 12 inches. Please contact us if you need a different size, or if you need us to make any alterations.
