100X HIGH STRENGTH LOW ALLOY
|
 |
|
100X is a high strength, low alloy steel with mechanical properties similar to A514. However, 100XF attains these properties without quenching and tempering. As a result, plates are free of scale and exhibit excellent flatness. It has a minimum yield strength of 100 ksi in thickness up to 3/4".

Cutting
100X can be cut with plasma, oxy-Acetylene, laser, and water jet as well as with abrasive cut off saws.
Machining
Drilling, countersinking, counterboring, tapping, milling, and general machining can be done with conventional equipment and carbide tools.
Forming
Plates can be cold formed to a minimum radius of 1.75t (bends perpendicular to the rolling direction) and 2.5t when bending parallel to the rolling direction.
Welding
100X has excellent weldability and can be welded with simple procedures and common consumables such as E7018.
