Alloy Steel Rectangle Bar 4142 Prehardened
Show full description
Alloy Steel Rectangle Bar 4142 Prehardened
Our 4142 prehardened alloy steel rectangle bar is a chromium-molybdenum alloy supplied at high hardness to eliminate the need for post-machining heat treatment. This material is widely used for manufacturing slides, wear plates, and heavy-duty tool holders that must withstand significant abrasion. It is a staple in the tooling and industrial machinery industries due to its exceptional toughness and wear resistance. Because it arrives pre-hardened, this steel saves manufacturers significant time and reduces the risk of part distortion. We offer these rectangle bars in a variety of dimensions to suit your specific industrial fabrication needs.
