This material is cold rolled proceesed and has a clean, smooth surface finish. The primary difference between hot and cold rolled 4130 sheet material is cosmetic, the mechanical strength is the similar.

Chromoly Plate

Chromoly plate is aircraft 4130 condition N (normalized), spec AMS-6345-C. This material is perfect for fabricating high strength custom tabs and brackets.

It is widely used in aviation and racing because of it's strength, weld-ability and ease of fabrication. Available in a large selection of thicknesses, in several pre-cut sizes to meet your project size requirements.

Due to how plate is produced it is not perfectly flat. Edges are either sheared or plasma cut, the heat generated by cutting does create a thin layer of hardness. It is recommended to grind off the edge hardness before attempting to cut this material - this will help reduce the potential of prematurely dulling the teeth of common cutting tools.

Note: Cut tolerance on this material is typically + or - 1/4".

Welding should always be performed by a qualified welder.
