## Mechanical properties (typical values, not certified minimums)

| Property | Value |
|---|---|
| Tensile strength | 625 MPa (cold drawn) |
| Yield strength | 530 MPa (cold drawn) |
| Hardness | 179–229 HB |
| Density | 7.85 g/cm³ |
| Machinability | ★★★☆☆ (3/5) |
| Corrosion resistance | ★☆☆☆☆ (1/5) |

## When to choose it

The default steel for shafts, axles, gears and studs: strong baseline plus localized induction hardening to 54–58 HRC on journals and teeth, with the rest staying machinable and weldable.

## When to look elsewhere

It through-hardens reliably only in thin sections — for large or through-loaded parts choose 4140 Q&T. When the same strength must come with corrosion resistance, 17-4 PH is the stainless answer.

## Typical applications

- Drive shafts and axles
- Gear blanks and sprockets
- Fixture bases and tooling plates
- Bolts, studs and pins
