    I was going to use it for a block-off plate on an engine, but it ended up using 8mm aluminum, instead, as it's easier to cut, shape, and drill, but this is quality SS, and I'll definitely use it on another project.

    It is what it is. What more can really be said? I've ordered two of these. Both arrived packaged very well. No warps, bends or scratches. Recommended!

1: 4130 steel introduction
AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum. It is similar to 4140 steel which has a higher carbon level (0.28-0.33%), giving 4130 material improved weldability, at the expense of through thickness strength. With the proper heat treatment it is also readily machined. Annealing ASTM 4130 alloy steel offers excellent ductility. AISI 4130 steel is usually supplied as round bar commonly in the hardened and tempered condition.
