4140 Product Guide

| 4140 Alloy Steel Tolerance Guide

Alloy Steel 4140 has high strength, high fatigue strength, toughness, torsional strength, and impact and abrasion resistance. Additionally, 4140 steel is highly ductile when annealed, though it requires more pressure as it is tougher than most carbon steels. 4140 is easily welded, but if this is done after hardening, it will also require a post weld heat treatment. This material is typically used in aerospace, oil, gas, automotive, agricultural, and defense industries, specifically gears, shafts, spindles, fixtures, and collars.

We offer 4140 in round tube, metric round tube, hex bar, metric hex bar, cold finish hex bar, rectangle bar, round bar, metric round bar, sheet plate, annealed sheet plate, and precision blanks.

Save on shipping!

You can select smaller lengths and switch from freight to standard shipping and save!

How does selecting smaller lengths reduce shipping costs?

Reducing your order from an oversize item that requires expensive freight services to a smaller bundle makes it eligible for less expensive (and faster!) standard shipping services.

*Material tolerances will remain +/- 0.125".

Single Heat Lot Required

Why are heat lots important?

Heat lots ensure consistent metal properties, full traceability, and quality control, which are critical for precision and reliability in your projects.

By selecting "Single Heat Lot Required" option, we ensure all cut pieces are sourced from a single heat lot for consistency in material characteristics.
